Answer:
85 ° is the answer to the question
Row D because if you plug in 10 for x you get 17 not 15z
The answer for w is w=3.5 <span />
Answer:
The answer is 207.
Step-by-step explanation:
If you do 1 ÷ 3 you'd get 3. Then move on too the 1 in 3105. 1 ÷ 1 equals 1. You do that with the 0 and the 5 in 3105. The last step too do is is do the same thing with the 5 in 15. Such as, 5 ÷ 3, 5 ÷ 1, 5 ÷ 0, and lastly 5 ÷ 5. Now if you understand just divide the two numbers in 15, which are 1 and 5 to get the quotient in the division problem. Hope this helps, I'm not the greatest at explaining!
(-7x² + 3) + (4x² + 2x - 1)
-7x² + 3 + 4x² + 2x - 1
(-7x² + 4x²) + (3 - 1) + 2x collect like terms
-3x² + 2x + 2
hope this helps, God bless!
