Answer:
I think it's 18
Step-by-step explanation:
P=2(l+w)=2(7+2)=18
it's been awhile I believe this is it
The known facts
- the sum of Natalie's age and Fred's age is 36
- the sum of Fred's age times four and Natalie's age is 72
Now, let's set up the equations where N is Natalie's age and F is Fred's age.
N + F = 36 ---- equation 1
N + 4F = 72 ---- equation 2
equation 2 minus equation 1 ---> 3F = 36 ---> F = 12, thus N = 24
Thus Fred is 12 years old, and Natalie is 24 years old.
Answer:
sqrt(1^2 + 2^2)
Step-by-step explanation:
I think the equation you're looking for may be y = -7.5 + 2.5x
