Answer:
The answer is x=-17/3
Step-by-step explanation:
The Steps:
-8 + 5(1 + x) = 2x - 20
-8 + 5 + 5x = 2x - 20
-3 + 5x = 2x - 20
-3 + 3x = -20
3x = -17
x = -17/3
Answer:
Height of larger cylinder is 13.72 ft
Step-by-step explanation:
If the cylinders are similar then their radius is suppose to be same .
formula for volume is π
where r is radius and h is the height
Let height of larger be H and smaller is 5 ft (given)

If you are using a calculator, simply enter 78÷260×100 which will give you 30 as the answer.
Length of the outer frame:4+2x
Width of the outer frame:3+2x
Area of the outer out frame"(4+2x)(3+2x)=15
Expand the equation:12+8x+6x+12x^2=15
Combine like terms :4x^2+14x-3=0
Slope is rise over run. This means your y is over your x. Start with subtracting your y values. It doesn't matter which way, just make sure you do the same with the x values. For this, I'll do it 6 - -9. The two negatives cancel out and make a positive, so your y value is 15. Now, do the same to the x values. -9 - -1 is -8. You're left with 15/-8. Since this can't be simplified, this is your final answer. Hope I helped!
