For this case we have the following functions:
f (x) = 36 + 4x
g (x) = x2 + 15
By matching both functions we have:
f (x) = g (x)
36 + 4x = x2 + 15
Rewriting we have:
x2 + 15 - 4x - 36 = 0
x2 - 4x - 21 = 0
Solving the polynomial we have:
(x-7) (x + 3) = 0
x = -3
x = 7
Taking the positive root we have:
x = 7
Answer:

Answer:
<h2>≈ 3 619 in²</h2><h2 />
Step-by-step explanation:
Surface area = 2×(base’s area) + lateral area
= 2×(base’s area) + (Perimeter of the base)×height
= 2×(π×12^2)+((2×π×12)×36)
=3 619,11473693544
Step-by-step explanation:
Note: I replaced all cos^2x terms using the identity
The area of one would be 50cm sq, so both would be 100 cm sq
because the height is 4 cm and the the bases are 7 cm, and Cm.
The formula is
A=a+b/2 *h
so is the base plus the base divided by 2. And then you multiply the height.
