NO!!!!!!! 1450/7 is correct because 6x+x=1456 7x=1456 x=208
Answer:
Look at the explanation for the answer!
Step-by-step explanation:
P = s*4
A = base*height
216 = 6s^2
can be solved in the following manner.
216/6=s^2
36 = s^2
sqrt(36) = s
flip for better overview
s = 6
the length of each side is 6 inches. :)
Answer:
Multiply the first equation by 4.
Step-by-step explanation:
4(x+y=3) which gives
4x+4y=12
and
4x-y=7
Then subtract the two equations and the x variable will be eliminated.
