Answer:
7) x = 2
8) x = 3
9) x = -7
10) x = 8
Step-by-step explanation:
7)
9x + 12 = 5x + 20
4x = 8
x = 2
8)
2x + 12 = 6x
4x = 12
x = 3
9)
62 + x + 125 = 180
x = -7
10)
arc WX = 2(35) = 70 degrees
12x + 14 + 70 = 180 degrees
12x = 96 degrees
x = 8
ok let me help
v=268.08 sooo
r(radius) which is 4
v=4/3 n r³ =4/3×n×4³ = 268.08
