Hey there!
First, let's list the factors of 40:
1 x 40, 2 x 20, 4 x 10, 5 x 8,
We need to figure out which pair of factors has a sum of 13.
1 + 40 = 41 --> Nope
2 + 20 = 22 --> Nope
4 + 10 = 14 --> Nope
5 + 8 = 13 --> Yes!
The two numbers that have a product of 40 and a sum of 13 are 5 and 8.
Hope this helps!

Step-by-step explanation:
Answer:
hello :
x = 1 and x = 3 are the solutions to g(x) = (x-1)(x+3).
because : g(1) = g(-3) = 0
Their error is that they divided 12 by 30, instead of 30 by 12 in order to get the price per pair
the correct unit price is $2.50 per pair
2.5 * 12 = 30
