Answer:
B
Step-by-step explanation:
(3x2 + 9x + 6) − (8x2 + 3x − 10) + (2x + 4)(3x − 7)
First distribute the (2x+4)(3x-7) to get 6x2-2x-28
After this just add the like terms for all parts of the expression.
(3x2-8x2+6x2)+(9x-3x-2x)+(6+10-28)
x2+4x-12
So you answer is x2+4x-12
Answer:
The difference is 4 degrees
Step-by-step explanation:
If its difficult for you to subtract negatives just switch them to a positive 1 and 5 now subtract 1 from 5=4 and because the measure being used is degrees the final answer would be 4 degrees.
