The answer to the equation in factored form is...(x+6)(x+7)
-4b-8 + -1b^2 +2b^3
-4(-2)-8+-1(-2)^2+2(-2)^3
8-8+2^2-4^3
4-64
60
Answer: The answer is B.
Step-by-step explanation:
Answer:
43
Step-by-step explanation:
the line is worth 180 degrees. subtract 90 and 47 because that is part of the 180. your left with 43 degrees which is what is missing. hope this helps!
Answer:
Square
Step-by-step explanation:
Plot points A (10,-4), B (6,-7), C (3,-3), D (7,0) on the coordinate plane.
Find slopes of the sides:

The slopes of opposite sides are the same, so opposite sides are parallel. The slopes of adjacent sides have product of -1, then adjacent sides are perpendicular.
Find the lengths of all sides:

All four sides are of the same length.
Quadrilateral ABCD is a square (all sides of equal length and perpendicular)
