A rectangle has an area of x^2-8x-48. If the width is (x+4) find the length.

inna [77]

Answer:x-12

Step-by-step explanation:

Area=x^2-8x-48

Width=x+4

Y is the midpoint of AB, The coordinates are A(-3,-7) and B(-1,1) What is the coordinate Y?

NISA [10]

The formla of a midpoint of AB:

$M\left(\dfrac{x_A+x_B}{2},\ \dfrac{y_A+y_B}{2}\right)$

We have A(-3, -7) and B(-1, 1). Substitute:

$x_M=\dfrac{-3+(-1)}{2}=\dfrac{-4}{2}=-2\\\\y_M=\dfrac{-7+1}{2}=\dfrac{-6}{2}=-3$

<h3>Answer: M(-2, -3)</h3>
