14. 7+3=10 and 7-3=4 so 7x2=14
Answer:
32
Step-by-step explanation:
1. find f(3) = 2x + 5
a) y = 2(3) + 5
b) y = 6 + 5
c) y = 11
2. find g(2) = 3x² + 2x + 5
a) y = 3(2)² + 2(2) + 5
b) y = 3(4) + 4 + 5
c) y = 12 + 4 + 5
d) y = 21
3. add f(3) + g(2)
a) 11 + 21
b) = 32
Answer: ΔBCD ≈ ΔBFD because of SSS
Step-by-step explanation:
1) We have two givens, which count towards two of the sides
2) BD is a reflective side, since they're the same
Answer:
I believe its 108°
Step-by-step explanation:
as it's a pentagon I looked up the angle of the top of a pentagon and found 108°
4x+9=2x−6
Step 1: Subtract 2x from both sides.
4x+9−2x=2x−6−2x
2x+9=−6
Step 2: Subtract 9 from both sides.
2x+9−9=−6−9
2x=−15
Step 3: Divide both sides by 2.
2x
