Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5
Hope this helped!
Answer:
x = 6
Step-by-step explanation:
0 = x^2 -12x + 36 solve by factoring ...or Quadratic Formula
0 = ( x-6)(x-6) shows zeroes ( both of them) are x = 6
Bigger is tripples other thing
small radius=5 so big is 5*3=15
small height=6 so big is 6*4=18

V=18pi15^2
V=18pi225
V=4050pi
pi=3.141592
V=12723.4476 cubic inchs
