P + v = 650....p = 650 - v
4p + 9v = 2925
4(650 - v) + 9v = 2925
2600 - 4v + 9v = 2925
-4v + 9v = 2925 - 2600
5v = 325
v = 325/5
v = 65.....video files
p + v = 650
p + 65 = 650
p = 650 - 65
p = 585....photo files
answer : Helena uploaded 9 times as many photo files as video files
65 * 9 = 585
Coefficients are added together because they are like terms, this can be proven with the distributive property. For example, x(2x+x)=2x^2+x^2=3x^2.
The commutative property of addition and the associative property demonstrate this.
The word "commutative" comes from "commute" or "move around", so the Commutative Property<span> is the one that refers to moving values around.

The associative property<span> states that you can add or multiply regardless of how the numbers are grouped. </span>

Answer:
<em>1. W = 50 ft</em>
<em>2. L = 110 m</em>
<em>3. L = 61 m</em>
Step-by-step explanation:
<u>Area of a Rectangle</u>
Given a rectangle of width W and length L, its area is calculated by the formula:
A = W.L
We are given three rectangle-shaped figures and are required to find different measures as explained below.
1. Length L=94 ft, Area = 4,700 square ft
We'll find the width by solving for W:


W = 50 ft
2. A=8,250 square m, W=75 m
We'll find the length by solving for L:


L = 110 m
3. A=1,586 square m, W=26 m
We'll find the length by solving for L:


L = 61 m
