Answer:
3x^2+2x+15
Step-by-step explanation:
3x^2+2x+2+(4x2)+5

34.5=4h+7c
(34.5-7c)/4=h
Put h= (34.5-7c)/4 into another equation
30.5=8h+3c
30.5=2(34.5-7c)+3c
30.5=69-14c+3c
11c=38.5
c=38.5/11
Put c=38.5/11 into one of the equations
to calculate the h.
That's false.
Let's see an instance:
10% of 300=30
20% of 100=20
It doesn't work here so it's false
