Answer:
Step-by-step explanation:
r(x)= (x-3)(x+5)
= x²+5x-3x-15
=x²+2x-15
Answer:
The formula to find the volume of a cylinder is V = πr2h
The diameter divided by 2 is the radius. 5.5 divided by 2 is 2.75
v = π2.752 16.5
V = 391.8
The answer is 391.8

Answer:
a. $3600
b. 6:5
Step-by-step explanation:
Put the question into an equation:
8x - 1/4 x 8x = 5x + 450
(simplify before solving) 6x = 5x + 450
(solve) 6x-5x = 450
x = 450
This means that Jimmy had 8 x 450 $ to start with = 3600
you can check this by subtracting a quarter of 3600 from 3600 and also multiplying 450 by 5 and then obtaining their difference. You get 450!
Now ratio of new amounts:
Jimmy now has: $2700
John still has: $2250
so ratio is 2700:2250
simplify to 6:5
Hope this helps
