Answer:
B
Step-by-step explanation:
15² - 12² = 81
√81 = 9
So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
Answer:
The answer is -20.
Step-by-step explanation:
(8 × 5) - (-6 × -10)
= 40 - 60
= -20
D) because only 4 is the common factor in the equation.
The answer is 65° because 115° and another number has to add up to 180°
