Answer 1

"rectangle's length is 4 feet more than width"

if we let w = width, how do you think we can we write an expression that represents length in terms of w?

Answer 2

4x

Answer 3

=

Answer 4

396

Answer 5

in this case, "more" means added to

so length = w + 4

Answer 6

oh okay

Answer 7

then area = l*w = (w+4)(w) = 396

solve for w

Answer 8

I had the right idea

Answer 9

18?

Answer 10

good so 18 = your ans.

Answer 11

this would be a right because we just did it

Answer 12

be careful, it's asking for the area equation not the length equation

area = lw = (w)(w+4) = w^2 + 4w

Answer 13

C

Answer 14

good
