For this case we must find an expression equivalent to:

We look for the factors of 10 and 30:
10: 1,2,5,10
30: 1,2,3,5,6,10,15,30
The greatest common factor of both numbers is 10.
Then, we can rewrite the expression as:

Answer:

Answer:
Ratios are proportional when the numbers in the ratio are multiply or divide by the same number. Ex. 3:5 = 6:10 = 12:20 = 9:15 (cross multiply the fractions and the results are the same 3/5 = 6/10)
Step-by-step explanation:
The surface area of a right rectangular prism is the amount of space on it.
Muna's claim is incorrect
<h3>How to determine the surface area?</h3>
The surface area of a right rectangular prism is calculated as:
A = 2 * (lw + lh + wh)
So, we have:
A = 2 * (8 * 16 + 8 * 12 + 16 * 12)
The above expression implies that Muna's claim is incorrect

Try the case if the triangle was a right triangle.
Then the longest side, 25, would be c or the hypotenuse.
9^2+24^2=25^2
81+576=625
657=625
This is not a true statement so the triangle is not a right triangle.
Hope this helps :)
