(x+2)^2+(x-3)^2-2x^2)

garri49 [273]

Answer:

13 - 2x

Step-by-step explanation:

(x +2)² + (x - 3)² - 2x²

Expand.

(x + 2)(x + 2) + (x - 3)(x - 3) - 2x²

x² + 2x + 2x + 4 + x² - 3x - 3x + 9 - 2x²

Bring all the like terms together then simply.

x² + x² - 2x² + 2x + 2x - 3x - 3x + 4 + 9

2x² - 2x² + 4x - 6x + 13

= 13 - 2x (or -2x + 13 )

Now, to find the unit rate:

So, by dividing we get the unit rate.

At the rate of 8 jumps Will takes 10 seconds.

Thus, for the rate of 1 jump he will take = $10\div 8=1.25\ seconds.$

Therefore, the unit rate is 1.25 seconds per jump.
