50 + 3x = 7x + 12
This is because of the exterior angle theorem.
Is this all one problem?
If not here:
56+64=120
30+54= 84
55+66= 121
40+25= 65
48+14= 64
24+40= 64
49+63= 112
62+15= 77
And the GCF of all of these is 1.

Answer:
90% confidence interval between 118.64 ounces and 124.16 ounces
99% confidence interval between 117.13 ounces and 125.67 ounces
Step-by-step explanation:
The quickest way to tell if a line is perpendicular is to find the slope, so you'll need to get the slope for both lines
PQ = ((-8) - (-9))/(2 - 0) = 1/2
and, for reference, a perpendicular slope is the negative reciprocal of the original (so we're looking for -2)
RS = (3 - 4)/(3 - 1) = -1/2
so, no, these two lines aren't perpendicular because the slope of RS is only the negative of PQ, not the negative <em>reciprocal</em>.
