Answer:
Step-by-step explanation:
A) 32 =4(x+2)
32 =4x + 8
24 = 4x
6 = x
B) 4(x-2) < 6x -18
4x-8 < 6x -18
so the area below the 6x-18 line on a graph. :?
Ok First put in you're question 1 2 3 4 the answer is 1 over 5

please follow me and give me a thanks because im new user in brainly pleease and mark me as brainliest.
Step 2 and all that follows is wrong because it should equal 20
The volume of the pipe is about 282.6 cubic feet.
First, we need to find the area of each circular cross section and subtract them to find the width of the pipe. The area of a circle is pi(r^2).
pi(3^2) - pi(2^2)
28.26 - 12.56 = 15.7
The width of the pipe is 15.7. Now, multiply that by 18 to find the volume.
15.7 x 18 = 282.6
