Let L=length and W=width and T=total lace
so
2L + 2W = T
and we know
T= 60 and W=20
so
2L + 2(20) = 60
2L + 40=60
2L = 20
so L= ?
What do you mean this question dosent make any sence
The number is 157, because it's 100-200, 10-5=5 (ones place) & 5+2=7 (tenths place)
First note that f(x) means the same thing as y. To solve for f(x) or y you need to plug in -5 for x and solve using the rules of PEMDAS
5(-5) + 40
-25 + 40
15
When x is -5 then y is 15
Hope this helped!
