Answer:
Surface area: 250
Volume: 1375
Step-by-step explanation:
Scale factor: 4:5
This means that the dimensions of the larger figure are 5/4 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(5/4) by the original surface area(160). So

Volume:
The volume is found multiplying the cube of the change(5/4) by the original volume(704). So

Answer:
The value of n must be a positive number.
Step-by-step explanation:
Area of a square is given by
where
is the side of the square.
Now, given the area of the square is
.
OA) If the area had been zero, i.e.,
then it means that there is no square at all.
OB) Also, it can not be any other number other than zero as this can include negative numbers as well. And an area being negative makes no sense. (OD) is eliminated as well.
So, the area should be positive.

Answer:
Simplifying
5(x + 9) = 5x + 45
Reorder the terms:
5(9 + x) = 5x + 45
(9 * 5 + x * 5) = 5x + 45
(45 + 5x) = 5x + 45
Reorder the terms:
45 + 5x = 45 + 5x
Add '-45' to each side of the equation.
45 + -45 + 5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
0 + 5x = 45 + -45 + 5x
5x = 45 + -45 + 5x
Combine like terms: 45 + -45 = 0
5x = 0 + 5x
5x = 5x
Add '-5x' to each side of the equation.
5x + -5x = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 5x + -5x
Combine like terms: 5x + -5x = 0
0 = 0
Solving
0 = 0
