Shakira and Evelyn disagree on the method used to find the perimeter of an equilateral triangle whose side measures 4n-2. Whose

wel

Answer:

<h3>Both are correct</h3>

Step-by-step explanation:

All the sides of an equilateral triangle are equal. Hence;

Perimeter of an equilateral triangle = 3S

S is one of the side length

Given;

S = 4n-2

Perimeter of the triangle = 3(4n-2)

This can also be expressed as P = S + S + S

P = (4n-2) + (4n-2) + (4n-2)

This shows that both methods are correct

3(3-y)+1=31<br> What’s the solution to “Y”?

laila [671]

3(3-y)+1=31
9-3y+1=31
10-3y=31
-3y=31-10
-3y=21
y=-21/3 = -7

the solution is y=-7

What is the slope of the line that passes through the points (-10, 8) and

vlada-n [284]

Answer:

$slope=3$

Step-by-step explanation:

Use the following equation the find the slope:

$\frac{y_{2}-y_{1}}{x_{2}-x_{1}} =\frac{rise}{run}$

Rise over run is the change in the y-axis over the change in the x-axis from one point to the other. This is also known as the "slope". Insert the known values:

$(-10_{x1},8_{y1})\\\\(-15_{x2},-7_{y2})\\\\\\\frac{-7-8}{-15-(-10)}\\\\\frac{-7-8}{-15+10}$

Solve:

$\frac{-7-8}{-15+10}=\frac{-15}{-5}$

Simplify. Two negatives make a positive:

$\frac{-15}{-5}=\frac{15}{5}$

Simplify fraction by dividing top and bottom by 5:

$\frac{15}{5}=\frac{3}{1} =3$

The slope is 3.
