Answer:
1) x = -2
Step-by-step explanation:
1) x + 7 + x + 11 = 14
2x + 18 = 14
2x = 14 - 18
2x = -4
x = -4/2 = -2
26 - 8 = 18.
James has 18 apples.
Answer: 6
Step-by-step explanation:
They are similar triangles so they have proportionality
For the small triangle the side is 2 and the hypoteneuse is 4, for the large triangle the side is 5 so the entire hypoteneuse is 10. 10-4 = 6 which is the missing side
Answer: perpendicular
Step-by-step explanation:
The answer
1 /3 radius^2 x height 3
Pi/3 *r^2 x 9 3 = 3 pi ^2
r=1, volume = 3 pi
r=2, volume = 12 pi
r=3, volume = 27pi
