Answer:
Step-by-step explanation:
To distribute means to multiply everything outside the parenthesis with everything inside the parenthesis, so in this case 7x8 then 7(x) then 7x2 so that is equal to 56 + 7x + 14, so combine the 56+14 so we get 7x + 70. I hope '7' is part of the problem and not the question number
Answer:
4h+17
Step-by-step explanation:
Hey There!
So to solve this problem we need to use distributive property
So we need to distribute the 3 to everything that is in the parenthesis ( h and 5)
3xh=3h
3x5=15
so now we have
3h +15 + h + 2
now we just combine like terms
3h+h=4h
15+2=17
So the answer is 4h+17

Answer:
42.4264069 i
Step-by-step explanation:
H: hours
45h + 45 = 30h + 75
15h + 45 = 75
15h = 30
h = 2 hours
45 ( 2 ) + 45 = 30 ( 2 ) + 75
90 + 45 = 60 + 75
135 = 135
Therefore the awnser is 2 hours.
