AB = 10 and AC = 2 StartRoot 10 EndRoot. What is the perimeter of △ABC?

0.7 • 48 = 7 • 4.8 = 28 + 5.6 = $33.6

Answer:

see explanation

Step-by-step explanation:

3x² + 5x + 2 = 0

(a)

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 3 × 2 = 6 and sum = 5

The factors are + 3 and + 2

Use these factors to split the x- term

3x² + 3x + 2x + 2 = 0 ( factor the first/second and third/fourth terms )

3x(x + 1) + 2(x + 1) = 0 ← factor out (x + 1) from each term

(x + 1)(3x + 2) = 0

(b)

Equate each factor to zero and solve for x

x + 1 = 0 ⇒ x = - 1

3x + 2 = 0 ⇒ 3x = - 2 ⇒ x = - [tex]\frac{2}{3}[/tex]

Answer:

x = 30.2

Step-by-step explanation:

You can do inverse operation to solve the problem.

9.5 + 20.7 = 30.2

x = 30.2

The surface area of this prism consists of:

Sprism = Sprism + Ssides

the bases of triangles the area of each one is

Atriangle = 1/2bh

Aonebases = 1/2bh

Abothbases = 2×1/2×bh = bh

Arectangle = l×w where l is the length and w is the width

Aside = ls

If the triangular base has unequal sides then you calculate the perimeter( P) of the triangle and multiply it by the height of the prism to get the area of the sides (lateral surface area)

If the base is an equilateral triangle then all three sides have equal areas and the lateral surface area becomes = 3ls

Sprism = bh+pl

The three numbers are 12, 18 and 24

Arithmetic progression

Let the 3 number in arithmetic progression be:

a-d, d, a+d ...

If their sum is 3, then;

a-d+d+a+d = 3

2a + d = 3 ........... 1

If the sum of their squares is 11, then;

(a-d)² + d² + (a+d)² = 11

a²-2ad+d²+d²+a²+2ad+d²  11

2a²+3d² = 11 ....... 2

Solving the equations simultaneously, d = 6 and a = 12

First-term = 12

second term = 18

Thirs term = 24

Hence the three numbers are 12, 18 and 24

Hope this helps you!!!!!! :D

Answer:

-3, 1, -1 or -1, 1, 3

Step-by-step explanation:

We can create the equation of x + x+d + x+2d = 3 or use the sum formula to end up with x = 1-d.

We can then calculate d by using 11 and creating an equation like this.

x^2 + (x+d)^2 + (x+2d)^2 = 11 -> (1-d)^2 + (1)^2 + (1+d)^2 =11 which ends up with d equaling -2 or 2

If we plug d into the sum formula we get

(2x + 2 * 2)/2 *3 =3

and

(2x + 2 * -2)/2 *3 =3

This leaves us with starting terms -1 and 3. We can then finish the arithmetic sequence for each case by just using d.

The values of each expression are given as follows:

1. p(a) = 4a² - 3.

2. r(2a) = 1 + 6a.

3. 3r(a) = 3 + 9a.

4. -4p(a) = -16a² + 12.

5. p(a^2) = 4a^4 - 3.

6. r(x+2) = 3x + 7.

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

Hence, for item 1, we have that:

p(a) = 4a² - 3.

(as the input variable is x, which appears only once in the expression).

For item 2, we have that:

r(2a) = 1 + 3(2a) = 1 + 6a.

For item 3, the expression is calculated in two parts, as follows:

For item 4, the expression is also calculated in two parts, as follows:

For item 5, we have that:

p(a²) = 4(a²)² - 3 = 4a^4 - 3.

For item 6, we have that:

r(x + 2) = 1 + 3(x + 2) = 1 + 3x + 6 = 3x + 7.

Answer:

Answer:

b Any length between 1ft and 6ft

Step-by-step explanation:

I am only 80% shure sorry

Step-by-step explanation:

the volume of such an object is created by multiplying the 3 side length dimensions :

length × width × height.

if you triple one of them, then you bring that factor 3 one time into the volume multiplication, and the volume also triples .

in our case that is 60×3 = 180.

FYI

if you would triple fire example all 3 dimension lengths, you would bring that factor 3 into the volume multiplication 3 times (once for every dimension).

and so the volume would increase by the factor

3×3×3 = 27.

Similar triangles may or may not have equal side lengths

Triangles ABC and DEF are similar by SSS theorem

The coordinates of the two triangles are:

A (0,0), B (4,0), C (0,2), D (0,0), E (2,0), and F (0,1)

Calculate the lengths of both triangles using the following distance formula

[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]

For triangle ABC, we have:

[tex]AB = \sqrt{(0 -4)^2 + (0 -0)^2} = 4[/tex]

[tex]BC = \sqrt{(4 -0)^2 + (0 -2)^2} = 2\sqrt 5[/tex]

[tex]CA = \sqrt{(0 -0)^2 + (0 -2)^2} = 2[/tex]

For triangle DEF, we have:

[tex]DE = \sqrt{(0 -2)^2 + (0 -0)^2} = 2[/tex]

[tex]EF = \sqrt{(2 -0)^2 + (0 -1)^2} = \sqrt 5[/tex]

[tex]FD = \sqrt{(0 -0)^2 + (1 -0)^2} = 1[/tex]

Divide corresponding sides of the triangles to calculate the scale factor k

[tex]k = \frac{AB}{DE} = \frac{BC}{EF} = \frac{CA}{FD}[/tex]

This gives

[tex]k = \frac{4}{2} = \frac{2\sqrt 5}{\sqrt 5} = \frac{2}{1}[/tex]

Evaluate the quotients

[tex]k = 2 = 2 = 2[/tex]

Since the quotients are equal, then the triangles are similar

Hence, triangles ABC and DEF are similar by SSS theorem

Step-by-step explanation:

Answer:

The answer is the first one "If they play a large number of turns, they should expect to average about 1.5 points per turn."

Step-by-step explanation:

This is essentially, because the 1st answer makes sense, while the other two are kind of ridiculous. Saying that the amount of points are exactly 3 points is not true, and saying it is possible to get 1.5 points on a turn is also impossible.

Answer is the ratio 3:5

Explanation:

To write the pants to shirt ratio, we write the numbers 12 and 20 in that order (since they correspond to the counts of each clothing item). Separate them with a colon to get 12:20

The last step is to divide both parts by the GCF 4

12/4 = 3

20/4 = 5

The ratio 12:20 fully reduces to 3:5

For every 3 pairs of pants, you have 5 shirts.

Answer:

[tex]\dfrac{-7}{2}[/tex]

Step-by-step explanation:

Here we are given a polynomial ,

[tex]\implies f(x) = 2x^3 + Ax^2 + 4x - 5 [/tex]

And the value of ,

[tex]\implies f(2) = 5 \dots (i) [/tex]

And we need to find out the value of A . Firstly substitute x = 2 in f(x) , we have ,

[tex]\implies f(2) = 2(2)^3+ A(2)^2 + 4(2) -5 [/tex]

Simplify the exponents ,

[tex]\implies f(2) = 2(8) + A(4) + 8 - 5 [/tex]

Simplify by multiplying ,

[tex]\implies f(2) = 16 + 4A + 3 [/tex]

Add the constants ,

[tex]\implies f(2) = 19 + 4A [/tex]

Now from equation (i) , we have ,

[tex]\implies 19 + 4A = 5 [/tex]

Subtracting 19 both sides,

[tex]\implies 4A = 5-19 [/tex]

Simplify,

[tex]\implies 4A = -14[/tex]

Divide both sides by 4 ,

[tex]\implies A =\dfrac{-14}{4}=\boxed{ \dfrac{-7}{2}}[/tex]

Hence the value of A is -7/2.
