Answer:
3x+8
Step-by-step explanation:
First, we can write the sum into a mathematical expression:
The sum of (x+5) and (2x+3)
(x+5)+(2x+3)
However, we do not need the parenthesis. It is unnecesarry here as we are just adding the two parts:
x+5+2x+3
Using commutative property, we can rearrange the symbols so that the x's are with each other and the numbers are with each other:
x+2x+5+3
Now we can simplify the expression:
3x+8
Hope this helped :)

What is the constant of proportionality? Write your answer as a whole number or decimal.
The constant of proportionality(k) between a yard and a foot is 0.33.
A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
The variable feet and yards are in direct proportion.
Let,
yard = k(feet).
1 = 3k
k = 1/3 = 0.33.
