Step-by-step explanation:

all you need is to solve the first term

2x² - (-3x²) = 5x² ,

b is the only answer with 5x² in it

Answer:

A

Step-by-step explanation:

-3x2 + 5y - 4xy + y2 - (2x2 - 4y + 7xy - 6y2)

use - sign to open bracket by multiplying

-3x2 + 5y - 4xy + y2 - 2x2 + 4y - 7xy - 6y2

collect like terms

-3x2 - 2x2 + 5y +4y - 4xy - 7xy + y2 +6y2

-5x2 + 9y - 11xy + 7y2

Answer:

3 hours 45 minutes.

Step-by-step explanation: 5 hours is 300 minutes. 3/4 of 300 is 225 minutes. 225 minutes is 3 hours 45 minutes. BAM

Answer:

h = 5x + 3

Step-by-step explanation:

I believe the volume should be [tex]5x^{3} + 13x^{2} + 6x[/tex]  in the question. Based on the correction:

[tex]V = 5x^{3} + 13x^{2} + 6x\\A = x^{2} + 2x\\V = A.h\\h = \frac{V}{A} = \frac{5x^{3} + 13x^{2} + 6x}{x^{2} + 2x} = \frac{x(5x^{2}+13x+6}{x(x+2)}=\frac{5x^{2}+13x+6}{x+2} = \frac{(x+2)(5x+3)}{x+2} = 5x+3[/tex]

Pythagoras theorem

Answer:

x ≈ 10,54 units

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 17² = 20²

x² + 289 = 400 ( subtract 289 from both sides )

x² = 111 ( take the square root of both sides )

x = [tex]\sqrt{111}[/tex] ≈ 10.54 ( to 2 dec. places )

Answer:

  60 feet

Step-by-step explanation:

We always assume that the shadow length is proportional to the height of the object casting the shadow. So, we have ...

  height/shadow = b/(72 ft) = (5 ft)/(6 ft) . . . let b represent the unknown height

  b = (72 ft)(5/6) = 60 ft . . . . . multiply by 72 ft

The building is 60 feet tall.

Answer:

gcf = 90

Step-by-step explanation:

270 = 2 · 3³ ·5

360 = 2³ · 3² · 5

multiply those factors in common:  2 · 3² · 5  = 18 · 5 = 90

Answer:

the answer would be p= -4

13-3p = -5(3+2p)

13-3p = -15-10p

13 = -15-7p

28 = -7p

p = -4

Answer:

s = 76 cm

Step-by-step explanation:

Here, we want to find the value of s in the triangle STU

Since we have the other two sides and the angle facing the missing side, we can use cosine rule

Mathematically, that would be;

s^2 = t^2 + u^2 - 2tu Cos S

s^2 = 96^2 + 98^2 -2(98)(96) cos 46

s^2 = 5749.31

s = √(5749.31)

s = 75.82 which is approximately 76 cm

Answer:

Angle WZY=31degrees

Step-by-step explanation:

5x+11=8x-1

11+1=8x-5x

12=3x

X=12/3

X=4

Substitute x=4 in 5x+11

5(4)+11=31

Answer: option d.

Step-by-step explanation:

We have the function:

y = f(x) = x^2  - 1

The output is 99 when y = 99, and the input is x.

Then we need to solve:

y = 99 = x^2 - 1

for x.

99 = x^2 - 1

99 + 1  =x^2

100 = x^2

√100 = x

10 = x

The correct option is d, input equals 10.

Answer:

(1)  4

Step-by-step explanation:

Isolate x.

[tex]\frac{x-2}{3}[/tex] + [tex]\frac{1}{6}[/tex] = [tex]\frac{5}{6}[/tex]

[tex]\frac{x-2}{3}[/tex] = [tex]\frac{5}{6}[/tex] - [tex]\frac{1}{6}[/tex]

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

[tex]\frac{x-2}{3}[/tex] × 3 = [tex]\frac{2}{3}[/tex] × 3

x - 2 = 2

x = 2 + 2

x = 4

Answer: Actually, it's never true.

Step-by-step explanation:

A kite is a quadrilateral defined to have no pairs of parallel sides.

A rhombus is a quadrilateral that has two pairs.

HOPE THIS HELPS

Hence Option B is correct i.e. sometimes true.

A Rhombus is a quadrilateral. It is a special case of a parallelogram, whose all sides are equal and diagonals intersect each other at 90 degrees.

A Rhombus has following major properties:

1)The diagonals bisect each other at 90 degrees,

2)Opposite sides are parallel and equal and

3)Opposite angles are always equal.

A kite has only one pair of opposite equal angles and only adjacent sides are equal. a kite may or may not hold property no. 3.

Hence , Option B is true.

2) 5

Step-by-step explanation:

Answer:

$18.28

Step-by-step explanation:

Step one:

given data

Kate had a sum of money,she spent 1/8 of the money on a skirt and the remaining amount on a handbag

let the total money be x

so  mathematically

x-1/8*x= 16

solve for x

x-x/8= 16

8x-x/8= 16

7x/8=16

cross multiply

7x= 8*16

7x=128

divide both sides by 7

x=128/7

x=$18.28

First, add up the two numbers in the ratio => 4+1, which gives us 5.

Now,

4/5×20 => 16

1/5×20 =>4

So, the required answer is 16:4.

Hope it helps!

The solution of dividing 20 in the ratio of 4:1 gives us 16:4.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We are given that the ratio of 4:1

First, we have to add up the two numbers in the ratio

4+1, which gives us 5.

Now,

4/5×20 = 16

1/5×20 = 4

Answer:

The number of cheery pieces in the box are [tex]18[/tex].

Step-by-step explanation:

Let the number of orange pieces in the box be [tex]x[/tex].

The box contains three times as many cherry pieces as orange pieces.

So, the number of cherry pieces in the box be [tex]3x[/tex].

It has four more grape pieces than cherry pieces.

So, the number of grape pieces in the box be [tex]3x+4[/tex].

There are [tex]46[/tex] total pieces in the box.

So, [tex]x+3x+3x+4=46[/tex]

[tex]\Rightarrow 7x+4=46[/tex]

[tex]\Rightarrow 7x=46-4[/tex]

[tex]\Rightarrow 7x=42[/tex]

Answer: See explanation

Step-by-step explanation:

My friends calculation is wrong. 40% of 80 is not 200. It is:

= 40% of 80

= 40/100 × 80

= 0.4 × 80

= 32

He should have represented the missing number by x. Therefore,

40/100 = 80/x

Cross multiply

(40 × x) = (80 × 100)

40x = 8000

x = 8000/40

x = 200
