Twelve and three hundred seveny-five
Step-by-step explanation:
Because vertical angles have equal measure, angle CPB = 90 degrees. By extension, angle CPQ + angle QPB = 90 degrees
So 2x+4x+12=90
6x+12=90
6x=78
x=13
Step-by-step explanation: The answer is B.
Answer:
-8x² - 6
Step-by-step explanation:
-1 + 2 will give us "+1"
+1 - 7 will give us "-6"
The answers given already are correct as they are properly matched, so we are left with the following to complete:
Thus,
-4y³ + 4y³ will give us "0".
We would be left with:
-3x² - 6 - 5x²
Collect like terms again
-3x² - 5x² - 6
-3x² - 5x² will give us "-8x²"
Final result would be:
-8x² - 6
