5. Prove that each of the expressions below are equivalent by evaluating the expressions given that p=2.
I
4(p-5) - 8
4p - 28

4P -28 Step-by-step explanation:

Both expression give -12

Step-by-step explanation:

4(p - 5) - 8

4p - 20 - 8

p = 2

4(2) - 28

8 - 20

- 12

4p - 28

p = 2

4 ( 2) - 28

8 - 28

-12

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
