Answer:
15 x 6 x 8
Step-by-step explanation:
total money is cost per lawn times number of lawns per week times number of weeks
cost per lawn is $15
number of lawns per week is 6
number of weeks is 8
so cost total money is 15 x 6 x 8 which is none of them
where did the 20 and 11 come from?
Let’s say Y = total amount of snow, and X = number of hours
Y = 4x + 18
4x=2x+6 set the two sides equal to each other
2x=6 subtract 2x to the other side
x=3 divide by 2
C
x^2+14x = (x+7)^2
7^2 = 49
so you would add 49 to both sides
