Answer:
<h2>
64π</h2>
Step-by-step explanation:
A = π r2
diameter : 2 = r
16 : 2 = 8
A = 8²π
A = 64π

Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = -2x + 3
g(x) = 2x + 3
f(3) is x = 3 for function f(x)
g(7) is x = 7 for function g(x)
<u>Step 2: Solve</u>
- Substitute in <em>x</em> [Functions]: f(3) = -2(3) + 3, g(7) = 2(7) + 3
- Substitute in functions: f(3) + g(7) = -2(3) + 3 + 2(7) + 3
- Multiply: f(3) + g(7) = -6 + 3 + 14 + 3
- Add: f(3) + g(7) = -3 + 14 + 3
- Add: f(3) + g(7) = 14
Answer:
C
Step-by-step explanation:
You start with 3 and subtract a number
the answer would be x=6
to find it you would set 3x-2 equal to 2x+4 and solve because the two sides would be equal if the triangles are congruent
hope this helps :)
