Answer:
60
Step-by-step explanation:
Since the angles A, D, and G are congruent then sum of given angles is eaqual to 180 degrees
x + 20 + 2x + x = 180 add like terms
4x + 20 = 180 subtract 20 from both sides
4x = 160 divide both sides by 4
x = 40
Angles B, E, and H are congruent so E is also = x + 20 and x = 40 so angle R = 60
Answer: y = 0
Step-by-step explanation:
1) Add all the numbers together, and all the variables
8y-6(4/3y-2)-12=0
2) Multiply parentheses
8y-24y+12-12=0
3) Add all the numbers together, and all the variables
-16y=0
y=0/-16
y=0
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
