The length of ND = 3 units
The length of N'D' = 6
6 / 3 = 2
The scale factor is 2
Yes it should bring it up to a C or maybe it will be a 70 or 75
Answer:
b=35 because 4+29=35 and that my statement for this answer so glad with the rest
2

Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.
With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)
