A rectangle has a length of 32feet less than 8 times its width. If the area of the rectangle is 96 square feet, find the length
lesantik [10]

L = 8w-32

w(8w-32) = 96

8x^2 - 32w - 96 = 0

w^2 - 4w - 12 = 0

(w  -  6)(w +  2  ) = 0

w+2=0 results in negative measures

w-6=0 ---> w = 6

width is 6

length is 8(6) - 32 = 48-32 = 16

9. The regular price of an item at a store is p
Fittoniya [83]

Answer: C: Expression B and D

Step-by-step explanation:

Say the item is $100. 20% of 100 is equal to 100 (20/100)

When you simplify, it equals 20. So 20% of 100 is 20. This $20 is the amount of discount you receive.

So you have to subtract $20 from the $100 to find the sale price. The sale price is $80.

Now plug in 100 for p in each equation. The equation that equals 80 is the answer.

Only equation B and D equals 80 when 100 is plugged in.
