Answer:

the blank =24x

Step-by-step explanation:

Assuming the expression is x^2 - ________x +144,

you can tell that this is in the form of a^2 +2ab+b^2.

If the "a" is squared, you would get x^2. And if the "b" was squared then you would get b^2.

So as the result, the expression is

(x-12)^2= x^2-24x+144

Answer:

The answer is 276.32 square yards.

Step-by-step explanation:

To solve for the surface area of a cylinder, use the surface area of a cylinder formula, which is SA= 2 $\pi$ rh + 2 $\pi$ $r^{2}$ . However, instead of using ( $\pi$ ), 3.14 will be used.

Next, plug in the information from the question into the formula. The formula will look like SA= 2(3.14)(4)(7) + 2(3.14)( $4^{2}$ ). Then, solve the equation, and the final answer will be 276.32 square yards.
