2x + 19 and x + 23 are alternate exterior angles. What is the value of x? *
Mamont248 [21]

Answer:

4

Step-by-step explanation:

2x+19=x+23

We simplify the equation to the form, which is simple to understand

2x+19=x+23

We move all terms containing x to the left and all other terms to the right.

+2x-1x=+23-19

We simplify the left and right sides of the equation.

+1x=+4

We divide both sides of the equation by 1 to get x.

x=4

What is the Width, explain how you got your answer (8 points btw)
asambeis [7]

Answer:

Based off of my calculations, I got 126

Step-by-step explanation:

The formula for area would be: A = L * W

So, when finding the width (W), you would need to divide the area (A) by the length (L).

Equation: W = A / L

Now you know the equation, all you need to do is plug in the numbers:

[84 divided by 2/3]

W = 84  /  2/3

After solving this, you would get: 126

So, W = 126.

To check if we got the correct answer, we could just multiply the length times the width:

126 * 2/3

Since this equation gives us 84 as the answer, 126 is the correct width.
