Question 189309: can you please Help Me?!!
For problems 7 through 9, the length of a rectangle is 3 inches more than its width.

180=(w+3)(w)
Write an equation for the situation above by multiplying the factors together and setting the equation equal to zero.
a.+w%5E2%2B3-180=0+
b.+w%5E2%2B3w%2B180=0+
c.+w%5E2%2B3w-180=0++

You can put this solution on YOUR website!
180=(w+3)(w)
Distribute the w to terms inside parenthesis:
180 = w^2 + 3w
Now, subtract 180 from both sides:
0 = w^2 + 3w - 180
.
Which is solution A
