Answer:
Yes, because P = 2x +2(12)
Step-by-step explanation:
As the formula for perimeter is 2(L+B).
Let L=x=18
B=12
Then, perimeter, P=2(18+12) = 2(30) = 60
Hence, we get the perimeter as 60 units.
Answer:(5m-3n)(2m+p)
Step-by-step explanation:
Hello,
Let's assume x the time the express runs.
56*x=35*(1.5+x)
==>21x=52.5
==>x=2.5 h =2 h 30 min
Answer:
-52.5 or -53
Step-by-step explanation:
Start by subtracting 18 from both sides. With you get 0.4=-21. Now divide 0.4 into both sides.
