Slope formula is y=mx+b so m is the slope and b is the y-int all u do is replace the numbers with the letters and they give u the formula which would be y=-8x-3
x = 4 and x = - 9
In both cases the angles inside the parallel lines are same sided interior angles
24x - 1 + 20x + 5 = 180
44x + 4 = 180 (subtract 4 from both sides )
44x = 176 ( divide both sides by 44 )
x =
= 4
Similarly
x + 109 + x + 89 = 180
2x + 198 = 180 ( subtract 198 from both sides )
2x = - 18
x =
= - 9
Answer:
The answer is 56
Step-by-step explanation:
I'm smart and you are dumb
For the given vectors
and 
The dot product of vectors a and b is defined as = 
So, 

= -16+12
= -4
48/4 = 12 for sides. Area is l x w so 12x12 = 144
