Answer:
x=106 degrees
Step-by-step explanation:
The two opposite angles in a parallelogram are always the same and we know 360 degrees in a parallelogram.
x+x+74+74=360.
2x+148=360
2x=212
x=106 degrees
For this case we must indicate the factors of the following expression:

To factor we must find two numbers that when multiplied result in -20 and when added, result in -12.
There are no two numbers that meet this condition. Thus, the expression is not factorizable with rational numbers.
Answer:
The expression is not factorizable with rational numbers.
Point-slope form: we need a point (x₀,y₀) and the slope "m".
y-y₀=m(x-x₀)
Data:
(1,1)
m=2
Therefore:
y-y₀=m(x-x₀)
y-1=2(x-1) This is the equation of the line in point-slope form.
Answer. y-1=2(x-1)
