Answer:
2ab(3b^2+2a+4)
Step-by-step explanation:
6ab^3 + 4a^2b + 8ab
2*3*a*b*b^2 +2*2*a*a*b +2*2*2*a*b
Factor out the common terms
2ab( 3*b^2 +2*a +2*2)
2ab(3b^2+2a+4)
Answer:
5/3
Step-by-step explanation:
19x=3+4(x+6)-2
19x=3+4x+24-2
19x-4x=3+24-2
15x=27-2
15x=25
x=25/15
simplify
x=5/3
Perhaps you mean to find the volume under

? It seems like you have to rely on calculus otherwise (in the case that you indeed mean

).
Assuming this, note that

describes the top half of a sphere with radius 8, which means the volume below this surface over the disk

is simply half the volume of the sphere. Thus the volume is
Answer:
4 is the coefficient of 4n
Step-by-step explanation:
A = length x width
15,000 = (w + 30) x w
15,000 =

+ 30w
0 =

+ 30w - 15,000
Use quadratic formula to find that w= -15 + or - 5

. Because distance cannot be negative, the width is -15 + 5

meters or approximately 108.39 meters. This means that the length is approximately 138.39 meters.
