Answer: 0
Step-by-step explanation:
2(2x-4)=4(x-2) - Start off by diong distributive property on both sides
4x-8=4x-8 - Add 8 to both sides toget rid of it
4x=4x - Divide both sides by 4
0 = 0 - The 2 equations are equal therefore the answer is 0
Hope this helps!

Answer:
(h+7j)*(h+2j)
Step-by-step explanation:
h^2+7hj+2hj+14j^2
h*(h+7j)+2j*(h+7j)=(h+7j)*(h+2j)
Answer:
a. A residual is how far off a point is from the expected value. For example, if I were to estimate the weight of my Southeastern Lubber Grasshopper, I would say it's maybe 5 ounces. But, in reality, it might be 4 ounces. So, the residual would be the reality minus the prediction, or 4 - 5, or -1 ounce.
b. The regression line is the line of predicted values for the points in the scatterplot. It tries to predict the points and make all the points be on the line.
Hope this helps!
