Answer:
10
Step-by-step explanation:
3c - 5 =2c +5
3c - 2c =5 +5
c=10
P=2(L+W)
l=x+7
w=x
P=2(x+7+x)
P=2(2x+7)
P=4x+14
hast to be greater than 154
P>154
4x+14>154
minus 14 both sides
4x>140
divide 4
x>35
Answer:
C & D
Step-by-step explanation:
Both have an odd amount of numbers, meaning there is a perfect middle.
You can use the Grouping method to solve that polynomial
