Answer:
r*6 + b*2
(a brainliest would be appreciated)
Answer:
V = 15.7*x^2 + 125.6*x + 251.2 I'd use this as an answer, but it depends how you have been told to treat pi. This answer is also possible.
V = 5*pi*x^2 + 40*pi*x + 80*pi
I can't really tell you which one to use.
Step-by-step explanation:
Givens
V=pi*r^2 * h
pi = 3.14
r = (x + 4)
h = 5
Solution
V = pi * (x + 4)^2 * 5
V = pi * (x^2 + 8x + 16)*5
V = pi * (5x^2 + 40x + 80) Now the question is what to do with pi.
V = 5*pi*x^2 + 40*pi*x + 80*pi
That one possible answer. The other is to give pi a value
V = 15.7*x^2 + 125.6*x + 251.2
10x - 12 + 10 = 18 - 20
10x - 2 = -2
10x = 0
x = 0
Answer:
(19x-290)/(4(x+2)(x-6)
Step-by-step explanation:
Apply Fraction Rule:
(41)/(4x+8)-(11)/(2x-12)
Factor:
(41)/4(x+2)-(11)/(2x-12)
Factor:
(41)/4(x+2)-(11)/2(x-6)
LCM:
(41)(x-6)/(4)(x+2)(x-6)-(22(x+2))/(4)(x+2)(x-6)
Expand:
= (19x-200)/4(x+2)(x-6)
