Hi, there!
I'm not sure what you want to solve in these equations. Please provide me with more details. I am sorry if you were looking for answers to the question, but I simply do not know what you are asking for.
Thanks!
-97 = 3x - 12x - 16
Simplify more
-97 = -9x - 16
Add 16 to both
-81 = -9x, x = 9
Solution: x = 9
Let L and H represent length and height, respectively.
.. 20 ft = (4/5)*L
.. L = (5/4)*(20 ft) = 25 ft . . . . . . . . multiply by the reciprocal of the coefficient of L
.. H = (2/9)*(L +20 ft)
.. = (2/9)*(25 ft +20 ft))
.. = (2/9)*(45 ft) = 10 ft
The volume is the product of length, width, and height.
.. V = (25 ft)*(20 ft)*(10 ft) = 5000 ft^3
(S + 12) + (3s - 8)
= s + 12 + 3s - 8
= s + 3s + 12 - 8
= 4s + 4
here is your answer
