Answer:
x=14
y=140
Step-by-step explanation:
Using (9x+14) + (3x-2) = 180, we can solve this equation.
First add like values giving you 12x+12=180. Then subtract 12 from both sides giving you 12x=168.
Then divide both sides by 12 giving you x=14.
Finally, just simply set 9x+14 equal to y and substitute x for 14. This gives you 140=y

Answer:
322.63%
Step-by-step explanation:
Volume of square pyramid = 1/3a²h
a = base side length ; h = height
Volume of pyramid A :
a = 18 ; h = 9
V = 1/3*18²*9
V = 18² * 3
V = 972 in³
Volume of pyramid B = 3136 in³
Volume of pyramid B / Volume of pyramid A
(3136 / 972) * 100% = 322.63%
