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

Answer:
W = (1/7) t
Step-by-step explanation:
At t = 0, W = 0
At t = 56 minutes , W = 8 inches
W = k*t The y intercept = 0 because t = 0 W = 0
8 inches = k * 56 minutes
k = 8 / 56
k = 1/7 inches / minute
W = (1/7) t
