The length of a rectangle is the sum of the width and 4. The area of the rectangle is 32 units. What is the width, in units, of the rectangle?

b=4

Step-by-step explanation:

Lets a be lenght and b width. From text we have:

a=b+4

a*b=32

Put the first equation in the 2n, we get:

(b+4)b=32

b^2+4b-32=0

b^2+8b-4b-32=0

b(b+8)-4(b+8)=0

(b+8)(b-4)=0

So it must be b=-8 or b=4. We know that width cannot be negative, so it is 4.

no i do not : ( what is it?

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
