Here is the set up:

x
x + 2
x + 4

x^2 + (x + 2) + (x + 4)^2 = 170

Take it from here.

I think that the answer is A, because in the range, none of the numbers should be the same, and the numbers are all different in choice A

Answer:

T = 3.50 + 1.50G

Step-by-step explanation:

G = number of games

T = total cost

total cost = cost of shoes + cost per game

T = 3.50 + 1.50G

I'm not 100% positive, but it's my best guess.

Answer: $\frac{2x(5x + 1)}{4x - 1}$

Step-by-step explanation:

$\frac{4x^{3}-12x^{2}}{4x^{2}+7x - 2}$ ÷ $\frac{2x^{2}-6x}{5x^{2}+11x + 2}$

= $\frac{4x^{2}(x - 3)}{(4x - 1)(x + 2)}$ ÷ $\frac{2x(x - 3)}{(5x + 1)(x + 2)}$

= $\frac{4x^{2}(x - 3)}{(4x - 1)(x + 2)}$ x $\frac{(5x + 1)(x + 2)}{2x(x - 3)}$

= $\frac{2x(5x + 1)}{4x - 1}$
