Let's say that the number we are looking for is called 'x'.
3 * x = 40
3x = 40
To solve for 'x', we will need to divide both sides by 3.
3x/3 = 40/3
40/3 or 13 1/3 can be multiplied by 3 to get 40.
THe scale factor = 5/2 = 2.5
So the first statement is false
and the second statement is True

Answer:
190cm²
Step-by-step explanation:
there is 2 types of sides on this. the top and bottom are the same, the front, back, left, and right are the same.
We first calculate the surface area of the top and bottom.
5x5=25
now we multiply that by 2 because the top and bottom are the same
25x2=50
now we look at the remaining 4 sides. the sides on these are 7 and 5 so we do
7×5=35
since we have 4 sides, we multiply the answer by 4
4×35=140
we add the sums together
140+50=190cm²
This equals 19.872.
If you multiply 7.2 by 12 and 0.23 then you would get 19.872 then to round it to the nearest hundredth it would be 19.902 because 7 is a greater number than 5 so that would make the 8 into a 9 and then 7 into a 0 and then you would keep the 19 and the 2
