To multiply you have to distribute. 3(h-5) will be 3h-3(5) which is 3h-15. So the answer is 3h-15
For #1 you need 8 pounds of apples
You subtract (-) 18 from both sides. so 200-18= 182 & 18-18=0. so 182=2m is left. divide both sides by 2 to make the m by itself. 182/2= 91 & 2m/2=1. 91=m
Answer:
Option 2 is correct that is
and
and 
Step-by-step explanation:
We have been given with the expression 
We will simplify the given expression by factorisation we will get
Taking x as common from first two terms in numerator and 2 from last two terms in numerator
Similarly, take x common from first two terms and 9 from last two terms in denominator we will get

After arranging the terms we will get 
Taking out the common factor which is (x-12) from numerator and denominator it will get cancelled we will get

Hence, Option 2 is correct that is
and
