Answer:
+70 or -70, depending on how you rewrite the equation
Step-by-step explanation:
A quadratic equation in standard form can be written as ...
ax² +bx +c = 0
When this equation is written in standard form, it could be either of ...
17x² +30x +40 = 0 . . . . . . . . . . add 17x²+30x to both sides
or
-17x^2 -30x -40 = 0 . . . . . . . . . subtract 40 from both sides
__
In the first case, a = 17, b = 30, c = 40 and (b+c) = 70.
In the second case, a = -17, b = -17, c = -40 and (b+c) = -70.

<em>Additional comment</em>
I personally prefer a positive leading coefficient, but it is less work to subtract 40 from both sides than to subtract 2 terms from both sides. Check your curriculum materials for the preferred rewrite in this case.
2x - 3
If you divide 6x^2 -9x by 3x you get 2x-3

Answer:
33.33%
Step-by-step explanation:
The computation of the percentage increase in the number of car washed is as follows;
= (Number of cars washed in next weekend - number of cars washed in one weekend) ÷ (number of cars washed in one weekend)
= (112 cars - 84 cars) ÷ (84 cars)
= 28 cars ÷ 84 cars
= 33.33%
