Answer:
The answer is 5x^2+32x-21
Step-by-step explanation:
To find the area of a rectangle, you have to multiply the length by the width. Then, you will get the equation of (5x-3)(x+7). Then, multiply these two together, therefore getting 5x^2+32x-21.
the answer is seven.
The A
since parallel lines have the same slope, If the slope of AB is -3 then the slope of CD will also be -3
