Answer:
18x+36
Step-by-step explanation:
9(2x+6) - 18
Distribute
9*2x + 9 *6 -18
18x +54 -18
Combine like terms
18x+36
Radius times 2 = diameter which would be 10 times 3.14 is 31.4 so it’s 31.4
4.125 x 14 = 57.75
So 57.75 is the answer and I have to show my work
A and b because they both match with the following letters
16.45 is equal to 16.450, so 16.454 is grater.
Hope this helps!
