Answer:
D. -10
Step-by-step explanation:
The sum of a triangle = 180°, therefore,
64° + 63° + x + 63 = 180°
Add like terms
x + 190° = 180°
Subtract 190 from each side
x + 190 - 190 = 180 - 190
x = -10
X^2 - 7x = 0
Factoring:-
x(x - 7) = 0
x = 0' x - 7 = 0 so x = 7
Solution is 0, 7.

Answer:
Simplifying
Result: 18x - 12y
Step-by-step explanation:
I believe you simplify the expression, by using -2, the number outside the bracket, to multiply with the numbers within the bracket.
-2 x -9x = 18x
-2 x 6y = -12y
