So to do this add 40 and 25 together to get 65.
Then multiply 72 by 25 to get 1800.
Then multiply 78 by 40 to get 3120.
Then add 3120 and 1800 to get 4920.
Then divide 4920 by 65 to get 75.69.
Answer = 75.69
Hope this helps!

Answer:
It is True.
Step-by-step explanation:
f(x) can be written as a symbol which represents function.
Three feet in a yard, so there are 9 square feet (3^2) in a square yard.
As a result, it will take 1/9th of the time to mow 600 square feet.
1.5 hrs = 90 mins
1/9th of 90 mins = <u>10 mins</u>
The new perimeter will be 3 times the old perimeter.
Original perimeter:
2(8+7) = 2(15) = 30 yds
New perimeter once they are tripled:
3 x 8 = 24
3 x 7 = 21
2(24+21) = 2(45) = 90 yds
30 x 3 = 90
