You need to factor the numerator and denominator...
(2x^2+4x-2x-4)/(2x^2-2x-2x+2)
(2x(x+2)-2(x+2))/(2x(x-1)-2(x-1))
((2x-2)(x+2))/((2x-2)(x-1)) so the (2x-2)s cancel out leaving
(x+2)/(x-1)
Using linear functions, the inequality that represents when Gilberta has more wallpaper left in her room than María has in hers is: t < 5.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
For this problem, we consider:
- The initial amount as the y-intercept.
Hence the amounts Gilberta and Maria have left after t hours are given by:
Gilberta has more papers when:
G(t) > M(t).
Hence:
35 - 4.3t > 30.5 - 3.4t
-0.9t < -4.5
Multiplying by -1:
0.9t < 4.5
t < 4.5/0.9
t < 5.
Hence the inequality is:
t < 5.

I = Prt
Interest on CD = 0.0425 x $1,800 = $76.5
Interest on savings = 0.0275 x $1,800 = $49.5
Difference of interest on CD and Interest on savings = $76.5 - $49.5 = $27
Therefre, he will earn $27 more if he invest in a CD rather than in a savings.
For this case, the property you can use is the following:
Commutative property.
We have then that:
14 (20 + 2) = 280 + 28 = 308
Equivalently:
14 (2 + 20) = 28 + 280 = 308
Either way the result is exactly the same.
Answer:
Commutative property.
Divide .30 (30%) with 60
60/.30 = 200
200 is your answer
hope this helps
