Ok first take out the GCF which is 3 in this case.
Answer:
5(4 + 3c) - 12 = 15c + 8
Step-by-step explanation:
1st step, expand it to make it a little easier to solve, 20 + 15c - 12
2nd step, subtract, 20 - 12 = 8
3rd step simplify, 15c + 8
A = about 295.86 if you the diameter then you know what the radiaus is. the formula is A=πr(r+h^2+r^2<span>)</span>
The answer is d) the mathematical work shown above is correct<span>proof
</span>a+b-2(ab-a) = a+b-2ab+2a = <span>3a+b-2ab
</span>
If it gives you your total, and another number, divide the 2
example:
25 • x = 75
75/25= 3
x=3
