Answer:
B. 2x + x = 90°
Step-by-step explanation:
A right angle is equal to 90 degrees. This line appears to be splitting a right angle, so adding both should equal 90 degrees.
Answer:
The answer is (C) Y = 3x² - 24x + 18
Step-by-step explanation:
Y = 3(x-4)² - 22
First step is to simplify (x-4)²
⇒ Y= 3(x-4)(x-4)-22
⇒ Y= 3(x²- 4x - 4x + 16) - 22 = 3(x² - 8x + 16) - 22
Next step is to open the parenthesis
⇒ Y = 3x² - 24x + 48 - 22
The final step is to collect like terms and simplify the equation
⇒ Y = 3x² - 24x + 26
