Answer:
A. x+5 b. 4b+12c+11
Step-by-step explanation:
2(x+10)
2*x = 2x
2*10 = 20
2x+10
divide to simplify
x+5
B.
3(4b+12c+11)
12b+36c+33
4b+12c+11
Divide both by the least common denominator which is 4
The answer is 2/3
perimeter = 2width + 2 length
102 = 2(x+9) + 2x
102 = 2x + 18 +2x
102 = 4x +18
84 = 4x
21 = x
Length = x = 21 inches
Width = x + 9 = 21 + 9 = 30 inches
Answer:
$30
Step-by-step explanation:
Charlie offers it to 14 teammates 4 of them don't want one.
