Answer:
a = 36 , b = 6
Step-by-step explanation:
expand the right side using FOIL and compare coefficients with like terms on left side.
(x - b)²
= x² - 2bx + b² , compare to x² - 12x + a , then
- 2b = - 12 ( divide both sides by - 2 )
b = 6
and a = b² = 6² = 36
Answer:
Number of one-dollar bills each child gets: 12 dollars
Dollars left over: 1 dollar
Step-by-step explanation:
25/2=12.5
so round down to 12 cause 13(2) is 26 and you only have 25.
so 12(2)=24.
Each kid will get 12 dollars and there will be 1 dollar left over.

Definition of an exterior angle
At each vertex of a triangle, an exterior angle of the triangle may be formed by extending ONE SIDE of the triangle. See picture below.
Calculating the Angles
We can use equations to represent the measures of the angles described above. One equation might tell us the sum of the angles of the triangle. For example,
x + y + z = 180
