Quotient: 5x^2+2x+4
remainder: 6x+3
Answer: 1296π
Step-by-step explanation:
To find the surface are if a square, we have to use the formula:
= 4πr²
= 4 × π × 18²
= 4 × π × 324
= 1296π
Therefore, the surface area of the sphere is 1296π
Answer:
x = -5/2
Step-by-step explanation:
4−(2x+4)=5
Distribute the minus sign
4 - 2x -4 = 5
-2x =5
Divide by -2
-2x/-2 = 5/-2
x = -5/2

Answer:
x = 32
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(x+18) * 18 = 30^2
(x+18) * 18 = 900
Divide each side by 18
(x+18) * 18/18 = 900/18
(x+18) = 50
Subtract 18 from each side
x+18-18 = 50-18
x=32
