Answer:
a = -3 and b=5
Step-by-step explanation:
Given that 10 can be written as 2*5 or √2*√2*5, and √18 can be written as √(2*9) or √2*√9 or 3√2, you can write the fraction as:
![\frac{5\cdot\sqrt2\cdot\sqrt2-3\sqrt2}{\sqrt2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Ccdot%5Csqrt2%5Ccdot%5Csqrt2-3%5Csqrt2%7D%7B%5Csqrt2%7D)
So getting rid of the √2 factor, you get 5√2 - 3, so a=-3 and b=5

Answer:
5/11 amperes ≈ 0.455 amperes
Step-by-step explanation:
The applicable formula for the current (I) is ...
I = P/V . . . . where P is power in watts, and V is voltage in volts
I = (50 watts)/(110 volts) = 5/11 amperes
R^2+r-8r-8=0
r(r+1)-8(r+1)=0
(r+1)(r-8)=0
r+1=0, r=-1
r-8=0 , r=8
answer: r=-1 or r=8
