Answer:

(2p+9)^2

Step-by-step explanation:

We know this is a perfect square trinomial

a^2 +2ab +b^2 = (a+b)^2

a = 2p   b = 9

a^2 = 4p^2

2ab = 2*2p*9 = 36p

b^2 = 81

Check

4p^2 +36p+81 = (2p+9)^2

Please help I am desperate
Phoenix [80]

Answer:

see below

Step-by-step explanation:

72pi cubic inches

1/3 pi r ^2 * h = 72 pi

1/3 r^2 h = 72

You can theoretically find infinite answers to this and get enough points for the semester where you don't have to do work anymore. I will list a couple more possible answers below

r = radius, h = height

r = 2, h = 54

r = 3, h = 24

r = 4, h = 27/2

r = √(1/pi), h = 72pi

bija089 [108]

Answer:

= 7x/2 + 30

Step-by-step explanation:

(9/4x+6)-(-5/4x-24)

= (9/4 x + 6) + 5/4 x + 24

= 9/4 x + 5/4 x + 6 + 24

= 14/4 x + 30

= 7/2 x + 30

= 7x/2 + 30
