Have a beautiful and joyful day ahead.
Supplementay means adds to 180
x and y could be 100 and 80
x and y could be 1 and 179
acute means that it is less than 90
since we are not told what x or y is, y could or could not be acute
Answer:
B. -2x2 + 6x + 6.
Step-by-step explanation:
(2x2 + 4x + 3) - (4x2 - 2x-3) Distribute negative over the parentheses:
= 2x2 + 4x + 3 - 4x2 + 2x + 3
= 2x2 - 4x2 + 4x + 2x + 3 + 3
= -2x2 + 6x + 6.
