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
tigry1 [53]

Answer:

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.

Artemon [7]
Janet = 7.55 x 15(hours) = 113.25
Kelsey = 15.10 x 15(hours) = 226.50
Ty = 13.85 x 15(hours) = 207.76

To gets Kelsey’s wage per hour you do 7.55 x 2 and to get ty you do 15.10(Kelsey’s wage per hour) - 1.25 which is 207.76
