You first have to see if they have the same common denominators. If they do then the operation as in addition you add the numerator and denominator together and she if it can be reduced into a smaller number
A rectangle has 4 sides, two of different lengths..
P = 2(2x-5) + 2(2x+6)
P = 4x - 10 + 4x + 12
P = 8x + 2
The slope is the change in Y over the change in X
Slope = (10 - -13) / (14 -12)
Slope = 23/2
X² + 2x = 24
Organizing:
x² + 2x - 24 = 0

x'' = (-2 - √100)/2*1
x'' = -12 / 2
x'' = -6
Result: x = 4 or<span> x = - 6 .

Good studies! :)
8/12 is a fraction that is equivalent to 2/3.When simplified, the answer is 2/3 and when you multiply numerator and denominator by 4, the answer is 8/12
