Find the perimeter of the equilateral triangle 3x² + 5x + 12​

Answer:

The aspect of the lines that are the same is that they have the same slope while the aspect of the lines that are different is that they have different x and y-intercepts

Parallel lines are lines that do not meet in a xy-plane

If the parallel lines are vertical lines, they will both cut the x-axis at different points showing that they will have different x-intercept.

Similarly, if the parallel lines are horizontal lines, they will both cut the y-axis at different points showing that they will have different y-intercept.

Parallel lines are also known to have the same slope. This is the aspect that is common to both lines.

Step-by-step explanation:

Answer:

x = 12

Step-by-step explanation:

The midsegment VY is half the sum of the parallel bases , that is

VY = [tex]\frac{EF+CD}{2}[/tex] , then

3x + 18 = [tex]\frac{1}{2}[/tex] (x + 96) ← multiply both sides by 2 to clear the fraction

6x + 36 = x + 96 ( subtract x from both sides )

5x + 36 = 96 ( subtract 36 from both sides )

5x = 60 ( divide both sides by 5 )

x = 12

2x>1

x>1/2

Answer:

Step-by-step explanation:

Elga's age = x

Alvin's age = 3*x = 3x

Sum of their ages = 24

x + 3x = 24

4x = 24

Divide both sides by 4

x = 24/4

x = 6

3x = 3*6 = 18

Elga's age = 6 years

Alvin's age = 18 years

Answer:

Third option

Step-by-step explanation:

Given the following question:

Side c = 24 units

Angle B = 30 degrees
Angle C = 60 degrees
30 + 60 = 90
90 + 90 = 180
(all angles add up to 180 degrees)
Angle A = 90 degrees

Apply the law of sines:

[tex]a=c\times sin(a)[/tex]
[tex]a=24\times sin(60)=20.7846097[/tex]
[tex]20.7846097[/tex]
[tex]8 > 5[/tex]
[tex]20.8[/tex]

Now we have all the angles and two of the sides:

A = 20.8
C = 24

[tex]b=c\times sin(b)[/tex]
[tex]b=24\times sin(30)=12[/tex]
B = 12 units

Angle A - 90 degrees
Angle B - 30 degrees
Angle C - 60 degrees

Side AC - 12 units
Side BC - 24 units
Side BA - 20.8 units

Hope this helps.

Answer:

94.05 units is the perimeter of this pentagon.

Length of each side in pentagon: 2r × Sin(180/n)

                                where r is radius and n is number of sides

Using the formula: 2r × Sin(180/n)

                              : 2*16 * sin(180/5)

                              : 18.8 units

Perimeter = 5(18.8) units........5 as we know pentagon has 5 sides

                = 94.05 units

the slope goes by several names

• average rate of change

• rate of change

• deltaY over deltaX

• Δy over Δx

• rise over run

• gradient

• constant of proportionality

however, is the same cat wearing different costumes.

initial value of 3, namely when x = 0, y = 3, so we have the point (0 , 3) and it has a rate or slope of 3/4.

[tex](\stackrel{x_1}{0}~,~\stackrel{y_1}{3})\qquad \qquad \stackrel{slope}{m}\implies \cfrac{3}{4} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{3}=\stackrel{m}{\cfrac{3}{4}}(x-\stackrel{x_1}{0})\implies y=\cfrac{3}{4}x+3[/tex]

Answer:

2.25

Step-by-step explanation:

2.4-0.15=2.25 It should be right

Analyze problem

since the distance is the same, we will not need to do any solving in that part

so, the average of 80 and 100 is

(80+100)/2

which is 90

so, 90 miles per hour

The average travel time is simply the mean travel time between the given points.

The average time calculated with the help of following formula;

[tex]\rm Average \ Time = \dfrac{Sum\ of \ all \ data}{Number \ of \ data}[/tex]

a) The average time to travel the first 0.25m

The time travel in the first 0.25m are 2.24s, 2.21s, and 2.23s.

So, the average time to travel is:

[tex]\rm Time = \dfrac{2.24+2.21+2.23}{3}\\\\Time = \dfrac{6.68}{3}\\\\Time = 2.23[/tex]

The average time that it takes for the car to travel the first 0.25m is 2.23s.

(b) The average time to travel just between 0.25m and 0.50m

The time travel in the 0.50m is 3.16s, 3.08s, and 3.15s.

So, the average time to travel this distance is:

[tex]\rm Average \ time = \dfrac{3.16+3.08+3.15}{3}\\\\Average \ time = \dfrac{9.39}{3}\\\\Average \ time =3.13[/tex]

The average time to travel between both distances is the difference between the average time of each distance.

Then,

Average = 3.13 - 2.23 = 0.9 seconds

Answer:

3 = 10.50

7 = 24.5

10 = 35.00

Step-by-step explanation:

If this is wrong I am sorry.

Hope this helps

Step-by-step explanation:

This is it. Proportion

if 3 pounds of blue berries cost 10.50

1 pound of blue berries cost 10.50÷3=3.50

Therefore 7 pounds of blue berries cost

3.50 ×7= 24.50

2. Let a be the number of pounds of blue berries you can buy with 35.00

1 = 3.50

a = 35.00

a=35.00÷3.50

a= 10

Therefore, 35.00 is equal to 10 pounds of blue berries.
