That would be
(a-2)(a+10)
N=100
other angles=260
all interior angles of a quadrilateral add up to 360
1) 2 bags cost $4 - from the graph
2) 1 bag would be just $2
Answer:
-8b^3ax^2
Step-by-step explanation:
Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side and compare the coefficients of like terms on the right side.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b
Comparing like terms with - 6x² + 12x - 15
x - term → - 3a = 12 ( divide both sides by - 3 )
a = - 4
constant term → - 3b = - 15 ( divide both sides by - 3 )
b = 5
