Using the point (-2, 0) to substitute into point-slope form, we get the equation to be 
Answer:
Step-by-step explanation:

Using the quadratic formula:

Since the discriminant is negative, -31, there are no real roots
5x2(3x-1)+2(3x-1)factoring furhter gives(5x2+2)(3x-1)
Answer:
Mean absolute deviation is the average of the absolute deviations from the mean. It is a measure of variability, which gives us an idea about the spread of data points from mean. Therefore, the small MAD means the data points are less deviated from mean. And the large MAD means the data points are more deviated from mean.
Hence, smaller the MAD lesser the variation in data.
Area Y Square + Area of triangle
= 10x10+1/2x18x5
=100+9x5
=100+45
=145.
