First, a little housekeeping!!
1+1+7x2+7y3+3+2x2−y3 needs to be written as <span>1+1+7x^2+7y^3+3+2x^2−y^3. The " ^ " signifies exponentiation and is essential here.
Now combine like terms:
7y^3-y^3 + 7x^2 + 2x^2 + 1 + 1 + 3
You'll get 6y^3 +9x^2 + 5.</span>
Answer:
( the third choice)
Step-by-step explanation:
Let
be the radius of cylinder A and let
be the radius of cylinder B. We assume the heights of both cylinders are the same
Base circumference of cylinder A = 
Base area of cylinder B = 
In order to have
(2) have the same value as
(3) we must multiply by a factor of 
Step-by-step explanation:
x² + 12x = -35
x² + 12x + 35 = 0
(x + 5) (x + 7) = 0
x = -5 or -7
64 is the correct answer. The numbers are being multiplied. 1×1=1, 2×2=4, 3×3=9, 4×4=16, etc.
