Answer:1.40
2.20
3.100
4.39
5.7
7
Step-by-step explanation:
The answer is -6x+12 because you will have to Foil which is ( First, Outside, Inside, and Last). After you foil you would add the like terms to get the answer I got.
50% of 28 is 14 so 28+14= 42
3/8 written as an decimal is <span>0.375</span>
The equation to find volume is V=

r²h and you know all of your numbers other than h so you plug all that in. 100=3.14×2²×h → 100=3.14×4×h → 100=12.56×h → Divide 12.56 from both sides 100÷12.56=12.56×h÷12.56 → 7.96cm=h.
I hope that helps!
