Answer:
Step-by-step explanation:
a. The area of a rectangle is width * length. The width is 5x, and the length is 7x-2. This means the area is 5x*(7x-2). Distributing the 5x, we find that the area of the rectangle is 35x^2-10x.
b. To find the area when x is 4, we plug x=4, so 35*4^2-10*4=560-40=520.
c. same as above, we plug x=7, and get 1645 as our area.
