Answer:
x = √2 = 1.414
Step-by-step explanation:
5x-(x+2)^2=x^2-8+x
since (x+2)^2 = x^2 + 2(x)(2) + 2^2 = x^2 + 4x + 4
so
5x - (x^2 + 4x + 4) = x^2 + x - 8
-x^2 + x - 4 = x^2 + x - 8
x^2 + x^2 + x - x = -4 + 8
2x^2 = 4
x^2 = 2
x = √2 = 1.414

The answer is 555 i dont really know how to breake it apart
sorry
hw: 3/2hrs = 3×30 = 90mins
chores: 1/2hr = 1×30 = 30mins
sleep: 17/2hrs = 17×30 = 510mins
90+30+510=630mins=10.5hrs/day
I think it’s D because if you divide 25/20 you get 1.25 and the similar pair would be 15/12.
Saving I don’t know but please let me know :)
