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:
11
Step-by-step explanation:
Let 'x' represent the total distance from point A to point B
During the first hour he gets 0.25 of the way there: 0.25x
During the second hour he covers an additional 0.2 of the distance: 0.2x
During the third hour, he covers 0.3 of the distance: 0.3x
The total distance the biker traveled is:
0.25x + 0.2x + 0.3x = (0.25 + 0.2 + 0.3)x = 0.75x
The biker has: x - 0.75x = (1 - 0.75)x = 0.25x of the total distance left to go.
Use the -69th rule when solving, it will eliminate any divisible invisible future prime numbers. That being said, your answer is infinity.
