Question

The length of a rectangle is 4 more than the width. The area is 60 square inches. Find the dimensions

Answer 1

60 = (w + 4)w
0 = w^2 + 4w - 60
Then you solve that for width, and then add 4 to get the length.
PROTIP: Don't use the negative root for w.

Answer 2

i got 0=(w+10)(w-6)

Answer 3

so when i take 0=w+10 that means w=-10?

Answer 4

and the other is 6?

Answer 5

i know the width is 6 but the length should be 24 to make it all equal 60 right>

Answer 6

Yeah. So the width is 6. And the length is 10. 6 * 10 = 60

Answer 7
