Answer:
A
Step-by-step explanation:
to find (g ○ f)(3) , evaluate f(3) and substitute the value obtained into g(x)
f(3) = | 3 + 2 | = 5 , then
g(5) = - 5² = - 25
If 5y-10=0 it would equal 2. Add ten to both sides and then divide 5 to both sides which leaves you with y=2

Step-by-step explanation:
<u>Formula for circumference of a circle is</u>:
Circumference = 
<em>Given circumference of the ring is
</em>
<em>Now solving for the radius gives us:</em>

We know that area of a circle is
, substituting the value of r we found, we get the area as:
area (A) = 
Hence the Area (A), in terms of
is
Answer:
x = 2
Step-by-step explanation:
-10x + 9 = -11

x = 2
Answer:
-17y+16x
Step-by-step explanation:
-3(3y -2x) +2(5x-4y)
Distribute
-9y +6x +10x -8y
Combine like terms
-9y -8y+ 6x+10x
-17y+16x
