Step-by-step explanation:
g=m+13
g+m=113
use substitution
A function is said to even if it returns the same output when given two opposite inputs:

In your case, you have

And since
, the proof is concluded.
The other number is 1.25 .
proved to us , the first number is 5 .
let the other number is 'x' .
therefore we are having ,
the product of these numbers = 5x
the sum of these numbers = 5 + x
Also , the product of these two numbers is equal to the sum of these two numbers
so , 5x = 5 +x
4x = 5
x = 5/4 = 1.25
so the second number is 1.25
verification :
product of the numbers = 5 x 1.25 = 6.25
sum of the numbers = 5 + 1.25 = 6.25
Hence the result is correct
Therefore the other number is 1.25.

Answer:
The surface area of the prism is <u>480 in²</u>.
Step-by-step explanation:
Given:
The prism dimensions are 8in 15in 17in and 9in.
Now, to find the surface area:
So, to get the surface area we put formula:
a=8in, b=15in, c=17in and h=9in.
Surface area = 2A+(a+b+c)h.
Whereas, 
And, 
<em>Now, we find </em><u><em>s</em></u><em> first:</em>



<em>Then, we get</em><u><em> A </em></u><em>:</em>



<em>On solving we get:</em>

Now, putting the value of A in the formula to get the surface area:





Therefore, the surface area of the prism is 480 in².
