125 / 4 = 30 (for rounding), not sure how this is middle school mathematics.
Answer:
3
Step-by-step explanation:
Answer:
D. f(x)=3^x+5
Step-by-step explanation:
D. have a domain and range
Let Length = L
then
W=width = 2*L-18
Perimeter = 2(W+L)=2(2L-18+L)=36
divide by 2
3L-18=36/2=18
3L=18+18=36
L=36/3=12 => W=2*L-18=2*12-18=6
=>
Length = 12, Width=6
Check: 2(12+6)=2(18)=36 =perimeter ! checks!
