Answer:
infinite soulutions
Step-by-step explanation:
m+7=3+m+4
m+7=m+3+4 (Combine Like Terms)
m+7=m+7
Step 2: Subtract m from both sides
m+7−m=m+7−m
7=7

______
Answer:
w is the width
L is the length
p is the perimeter
w=9
L=27
___________________
Step-by-step explanation:
p=2[(L-4) + (w+1)]
⇔p=2[(3w-4) + (w+1)]
⇔p=2[4w-3]
⇔p=8w-6
⇔66=8w-6
⇔8w=72
⇔w=9
Then L=3w=27

If your looking for the x-intercept then is would be 2
Hope this helps
Answer:
Step-by-step explanation:
P = {x : x is a real number between 2 and 7}
{x: 3,4,5,6}
Q = {x : x is all rational number between 2 and 7}
{4 }
We know that P contains all the rational numbers between 2 and 7.
And P ∪ Q and Q ∪ P each of them contain all the real numbers which are between 2 and 7.
{3,4,5,6}
Here Q is the proper subset of P
P ∩ Q = Q ∩ P = Q= {4}
