The distributive property of multiplication is a very useful property that lets you simplify expressions in which you are multiplying a number by a sum or difference. Multiply, Combine, Solve.
We know that perimeter is the sum of all the sides.
We know the one side is 15 ft.
The other two are both equal to x, so the sides are the same length.
35-15= 20
Both of the sides together equal 20. Divide this in half to find the length of each individual side.
20/2= 10
x= 10
I hope this helps!

The interest earned in the account after three years is $720.
The formula for simple interest= P×T × R/100
Principal (P) = $4000
Time( T) = 3 years
Rate(R) = 6%
interest(I)= 4000×3 × 6/100
I = 72000 ÷ 100
I = 720
Therefore, the interest earned in the account after three years is $720.

Answer/Step-by-step explanation:
Rob is incorrect because the graph line don't go trough the origin.
If the graph of a relationship is a line or a ray through the origin, then it is proportional. If it is a line or ray that does not pass through the origin, then it is not proportional. Also, if it is not linear, then it is not proportional.
Proportional relationships in mathematics occur when two variables always change by the same multiple. Proportional relationships use the model y = kx, where k is a constant multiplier that shows the relationship between x and y. The graph is a straight line that always passes through (0,0).
