20 inches is 400
10 inches is 200
5 iches is 100
So 20+10+5=35
Which means 400+200+100= 700

Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3
3 over 7, 2 over 5, 2 over 3 so your answer is b. this is the correct answer I think because1/2 equals one half 2/2 equals 1 whole hope you understand what I meanunderstand what I mean
