Answer:
100
Step-by-step explanation:
V (x) = 5x²+ 5x
x=4
We plug in the x value:
V (x) = 5(4)²+ 5(4)
Now we sovle the equation:
5(4)² + 5(4)
5(16) + 5(4)
80 + 20
= 100
Hope that helps, and sorry if its incorrect

You would divide 100/20 and get 5. then u would multiply 9 times 5 equals 45 then add a decimal to get ur answer 0.45
Answer:
C
Step-by-step explanation:
Volume = bhd
Volume = (x + 3)(x + 8)(x²)
start with (x + 3) and (x + 8), factor:
x² + 8x + 3x + 24
x² + 11x + 24
now bring x² back:
(x² + 11x + 24)(x²)
x⁴ + 11x³ + 24x²
( y - 4 ) ( y² + 4 y + 16 ) =
= y³ + 4 y² + 16 y - 4 y² - 16 y - 64 = y³ - 64
If the result is the polynomial of the form:
y³ + 4 y² + a y - 4 y² - a y - 64
a = 16
