Answer:
5x^3+6x^2+x-7
Step-by-step explanation:
f(x) = 4x^3 - 2x and g(x) = x^3 + 6x^2 + 3x - 7,
f(x)
+ g(x)= 4x^3 - 2x+ x^3 + 6x^2 + 3x - 7
4x^3 + x^3 + 6x^2 + 3x- 2x - 7
Combine like terms
5x^3+6x^2+x-7
Answer/Step-by-step explanation:
Volume of a cylinder is given as V = πr²h
Where,
radius (r) = 6 cm
height (h) = 8 cm
Plug in the values
V = π*6²*8
V = π*36*8
V = π*288
V = 288π cm³ or 904.78 cm³
First you substitute into the equation is/of=%/100. By that, I mean, 119/x=70/100. Cross multiply to get 119(100)=70x. Solve for x=170
Answer:5
Step-by-step explanation:
2 hr 15 min = 2

hours = 2.25 hours
"how far" means distance ... so distance = rate x time
distance = 56 x 2.25 =
126 miles
"how long" means time ... so using the same formula
168 = 56 x time
divide both sides of the equation by 56 to solve
3 hours = time
