8 ( 12x + 4 ) = 96x + 32 8 ( 12x + 4 )
= 1920 + 32 OR = 8 ( 240 + 32 )
= 1952 = 1920 + 32
= 1952
8*12x = 96x 96*20 = 1920
8* 4 = 32 12*20 = 240
240*8 = 1920
The answer is y=-3

The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.
A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π
From the statement, we know that r2=2(r1).
<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have
5 x (r1)^2 = 80
Thus,
r1 = 4 and r2 = 8
