Find the value of x that makes m
n.
m
xº
2x

x = 60

Step-by-step explanation:

For the lines to be parallel, then

x and 2x are same- side interior angles and supplementary, thus

x + 2x = 180

3x = 180 ( divide both sides by 3 )

x = 60

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)

step-by-step explanation:

answer: 12/52

step-by-step explanation: my reasoning is that there are 12 face cards in a deck and a total of 52 cards in all.
