Answer:
(x-3) (x-5)
Step-by-step explanation:
x²−8x+15
note that the constant term is 15 and the x-coefficient is -8
step 1: List factors of 15 : ±1, ±3, ±5, ±15
step 2: observe the factors listed and ask ourselves the following questions:
1) What 2 factors in the list , when multiplied gives the constant 15
2) What same 2 factors when added gives the x-coefficient -8
by deduction or trial and error, we can see that -3 and -5, when multiplied gives 15 and when added gives -8. Hence these become the factors.
Hence the factors are
(x-3) (x-5)
Answer is A

1000 is better you get 1 staple for every $3 as opposed to 1 staple every $2.50
You get double for $0.50 more per staple
You need to convert gallons to ounces. 1 gallon = 128 fluid ounces. So to find the price of an 8 ounce glass of Moo Milk you need multiply 8/128 x 5.12. That equals $0.32.
