Answer:
D. 424 m³
Step-by-step explanation:
Use the formula for the volume of a cylinder
V =
r²h
Plug in the values we know
V = (3.14)(3²)(15)
V = 423.9 m³
This is closest to answer choice D, 424 m³
So, D is correct
Answer: y=-3x+5
Step-by-step explanation:
Slope-intercept form is y=mx+b. So to make your equation into slope-intercept form, simply subtract 3x from both sides, which results in y=-3x+5
6.4 is the answer hope this helps
1.

or if you mean (3x^3+5x^2+3x-7)+(8x-6x^2+6):

Answer:
X=11
Step-by-step explanation:
(10x+30)=140
-30 both sides
10x=110
Divide 10 both sides
X=11
