Answer:
x = 54°
y = 66°
Step-by-step explanation:
x + y = 120° (given)
x = y - 12
Then, y + y - 12 = 120°
(y + y) - 12 = 120°
2y - 12 = 120°
2y = 120 + 12 = 132°
y = 132/2 = 66°
x = y - 12 = 66 - 12 = 54°
There you go :)
Answer:
Choice C.
Step-by-step explanation:
For an expression to be equivalent you need to multiply or divide the 2 numbers in the original expression by the same number.
For example A is equivalent because both 125.78 and 1.23 have been multiplied by 100.
The odd one out is C because 125.78 has been divided by 100 but 1.23 has been multiplied by 10.
(A*x + B*x^2 + C)*(E*x + F)
