Answer:
See below.
Step-by-step explanation:
Formula: A = πr²
Since the radius is 4, we fill in the formula with the radius.
A = (3.14)4²
A = (3.14)16
A = 50.24

The answer is A. Please give brainless...
We have that
-7x-60=x²<span>+10x
</span>x²+10x+7x=-60
x²+17x=-60
(x²+17x+8.5²)=-60+8.5²
(x+8.5)²=12.25
(+/-)(x+8.5)=√12.25--------> (+/-)(x+8.5)=3.5
(+)(x+8.5)=3.5------> x=-5
(-)(x+8.5)=3.5------> x=-12
therefore
(x+5)*(x+12) is equivalent to -------> -7x-60=x²+10x
the answer is
(x+5)*(x+12)
