Answer:
x=10 x=-2
Step-by-step explanation:
(x − 3)(x − 5) = 35
FOIL
x^2 -5x-3x+15 = 35
Combine like terms
x^2 -8x+15 = 35
Subtract 35 from each side
x^2 -8x+15-35 = 35-35
x^2 -8x-20 =0
Factor
What 2 numbers multiply to -20 and add to -8
-10*2 = -20
-10 +2 = -8
(x-10)(x+2) =0
Using the zero product property
x-10 =0 x+2 = 0
x=10 x=-2
The students spent 43 minutes more playing video games or 58.65 % more times playing video games than reading. The consistency of reading was a range of 5 minutes whereas the video playing was a range of 21 minutes. The average reading time was 6 minutes and 6 seconds whereas playing videos was an average time of 10 minutes and 24 seconds. The plot will show a close proximity to reading and a wider proximity in video playing.
