                              x² - 8x = 65
                      x² - 8x + 16 = 65
               x² - 8x + 16 - 65 = 65 - 65
        x² - 4x - 4x + 16 - 65 = 0
x(x) - x(4) - 4(x) + 4(4) - 65 = 0
        x(x - 4) - 4(x - 4) - 65 = 0
               (x - 4)(x - 4) - 65 = 0
                       (x - 4)² - 65 = 0

It is actually (x - 4)² - 65.

What is the surface area of a cylinder with base radius of 4 and height 5
shtirl [24]

Answer:

A= 226.08

Step-by-step explanation:

The formula for the surface area of a cylinder is A=2πrh + 2πr^2

So, plug in the numbers. π(pi)= 3.14

A= (2 × 3.14 × 4 × 5) + (2 × 3.14 × 4²)

You could use a calculator for the last few steps.

Multiply what's in the first set of parenthesizes: I25.6

Now, multiply the numbers in the other pair of parenthesizes: 100.48

Lastly, add the two numbers together: 226.08

226.08 is the surface area of the cylinder.
