Answer:
x =20
Step-by-step explanation:
We can use similar triangles and proportions to solve. Take the smaller triangle side on top and the larger triangle side on the bottom.
11 10
---------- = --------------
11+121 10 +5x+10
Combine like terms
11 10
---------- = --------------
132 5x+20
Using cross products
11*(5x+20) = 10*132
55x+220 = 1320
Subtract 220 from each side
55x+220-220 = 1320-220
55x = 1100
Divide by 55
55x/55= 1100/55
x =20
Answer:
336 ft³ or 336 cubic feet
Step-by-step explanation:
Volume = Area triangle * height
Area triangle = 1/2(8 x 14)
Area triangle = 1/2(112) = 56 ft²
56 ft² * 6 ft = 336 ft³

Step-by-step explanation:
198=-4x+2(-6x+3), 198=-4x-12x+6, 198=-16x+6, collect the like terms, 198-6=-16x, 192=-16x, divide both sides by -16, 192/-16=-16x/-16, x=-12
