Answer:
56x^2 + 94xy
Step-by-step explanation:
(7x + 3y)(8x + 5y) =
56x^2 + 35xy + 24xy + 35xy = 56x^2 + 94xy
The task can be expressed in a following equation:
120%*a=80%*b
1.20a=0.80b
1.2a=0.8b
12a=8b
3a=2b
1) in terms of a:
3a=2b
b=3a/2=1.5a
a+b=a+1.5a
=2.5a
2) in terms of b:
3a=2b
a=2/3b
a+b=2/3b+b=
