Answer:
Step-by-step explanation:
(x² + 6x + 9)(x)= x²*x + 6x*x + 9*x = x³ + 6x² + 9x
Just plus in x for -3
f(x) = 4(-3)^2 + 3(-3) - 11
f (x) = 4(9) -9 - 11
f(x) = 36 - 20
f(x) = 16
Answer:
The correct answer is s³/6
Step-by-step explanation:
<u>Points to remember</u>
Volume of pyramid = (a²h)/3
Where a - side of base
h - height of pyramid
It is given that, a pyramid has a square base with sides of length s the height of The pyramid is equal to 1/2 Of the length of a side on the base
<u>To find the formula:-</u>
Here side length a = s and
height h = 1/2(s) = s/2
Volume = (a²h)/3
= (s² * s/2)/3
= s³/6
The correct answer is s³/6
