The answer is C.
SA = bh + (s1 + s2 + s3)H
SA = (6.8)(5.1) + (6.8 + 5.1 + 8.5)(2.5) = 85.68
Answer:
Yes.
Step-by-step explanation:
Just like normal algebra, you factor our the common factor, in this case, 5.
Thus,

First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100
Then do the same thing to the first number 8 so 8x2=16+8x1.5=20
then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
