The original price of the clubs will be $135.
If the clubs at Nine Iron are $8 less than Golf Pros, they are 112.
120 - 8 = 112
Now, we just have to find the original price. We can write and solve the equation below to find the original price.
x (0.83) = 112 Divide both sides by 0.83
x = $135
so it'd be the first, third and fourth one. all you gotta do is draw a vertical line through the middle of the 1st, 3rd and 4th.
No, there is not a product rule for integration.
To integrate (2x - 1)(6x + 5), start expanding the product:
(2x - 1)(6x + 5) = 12x^2 + 10x - 6x - 5 = 12x^2 + 4x - 5.
Now, I guess you know how to integrate that:
∫ (12x^2 + 4x - 5) dx = ∫12x^2 dx + ∫4x dx + ∫ (-5) dx = 4x^3 + 2x^2 - 5x + C
The expression would be written as:

n-3
N is any number. This expression means two-fifths of a number, subtract three. Now substitute 25 for n.

(25)-3
=10-3
=7
