Answer:

-8a(a+3b)

Step-by-step explanation:

(2a+6b)(6b−2a)−(2a+6b)^2

(2a+6b) {(6b−2a)−(2a+6b)(2a+6b)}

2(a+3b) (6b-2a-2a-6b)

2(a+3b) (-4a)

-2(a+3b) x 4a

-2 x 4a (a+3b)

-8a(a+3b)

An earthquake was felt throughout a circular area of 1,808.64 square miles. What was the radius of the circular area?

spin [16.1K]

A. 24 miles

Explanation:

the area inside a circle is given by:

$A=\pi r^2$

where r is the radius of the circle.

In this problem, we know the circular area:

$A=1,808.64 mi^2$

So we can re-arrange the equation above to find r, the radius:

$r=\sqrt{\frac{A}{\pi}}=\sqrt{\frac{1,808.64}{\pi}}=24.0 mi$

so, the radius of the circular area is 24 miles.

zepelin [54]

Step-by-step explanation:

f(x) = 4x + 5, g(x) = 9x − 4

(f-g)(x) = f(x) -g(x)

=4x+5-9x+4

=-5x+9

=9-5x
