Answer:
You prove the base angles are congruent by constructing the angle bisector through the vertex angle of an isosceles triangle. By constructing the angle bisector, we designed two congruent triangles and then used CPCTC to show that the base angles are congruent.

Answer:
20
Step-by-step explanation:
To calculate the sum of the residuals, subtract the predicted sales from the actual sales in the table below.
Actual sales 55 150 325 510 780 990
Predicted sales 40 150 300 500 800 1,000
This will show the change between them. Add each residual to find the sum.
55 - 40 = 15
150 - 150 = 0
325 - 300 = 25
510 - 500 = 10
780 - 800 = -20
990 - 1000 = -10
These add up to be 15 + 25+ 10 +-20 +-10 = 20

Answer:
Step-by-step explanation:
f (2/5 ) = −2/3*2/5 + 5
Which is -4/15+5
Which is 71/15
But it is not one of the multiple choices please update when you figure out where you copied incorrectly
(13x² + 5x) + 8x²
= (13 + 8)x² + 5x
= 21x² + 5x
