Answer:
-n-2
Step-by-step explanation:
Surface area
break it down
bottom and top
bottom=5 rectangle
top=2 triangles+2rectangle
areas
area of recatngle=lw
area of traignle=1/2lw
so total is
SA=(8 times 2.8)+(2.8 times 4.8) +(2.8 times 4.8)+(4.8 times 8)+(4.8 times 8)+(5 times 2.8)+(5 times 2.8)+(1/2 times 3 times 8)+(1/2 times 3 times 8)
(I'm not going to do all the math, just the result)
SA=178.08 yd^2
split the figure into 2 parts
top and bottom
bottom=rectagular prism=lwh
top=triangle tingie, wait, if we take 1/2 of it and put it with the other, half, we get a rectangular prism with 1/2 base so
bottom=8 times 2.8 times 4.8=107.52
top=1/2 times 8 times 3 times 2.8=33.6
add them
107.52+33.6=141.12 yd^3

Subtract 25.
25 - 25 + x < -40 - 25
Simplify
x < -65
_____
An inequality is solved exactly the same way an equation is solved, with one exception.‡ Multiplying or dividing by a negative number reverses the sense of the inequality:
2 > 1
-2 < -1 . . . . multiplied by -1
___
‡ The exception can be generalized to the use of any function that reverses the ordering of its arguments. In Algebra, about the only function we use that has negative slope is the cosine function (and its inverse). You rarely see these used in inequalities.
