Answer:
C
Step-by-step explanation:
No, she didn’t use the entire fraction as the base, so wrote the expanded form wrongly.
and I know this cuz I took the test

Answer: -2</h3>
===============================================
Explanation:
We use the remainder theorem. This is the idea where if we divide P(x) over (x-k), then the remainder is P(k).
Comparing x+1 to x-k shows that k = -1
It might help to rewrite x+1 as x-(-1) to get it into the form x-k better.
Plug this k value into the function
f(x) = 2x^6 + 3x^5 - 1
f(-1) = 2(-1)^2 + 3(-1)^5 - 1
f(-1) = 2(1) + 3(-1) - 1
f(-1) = 2 - 3 - 1
f(-1) = -1 - 1
f(-1) =-2
The remainder is -2
We can confirm this through synthetic division or polynomial long division.
Answer:
x = 170/34 = 5
Step-by-step explanation:
The sum of angle 1 and angle 2 is 180 degrees. They form a straight line.
So, just add the two equations together, set them equal to 180 and solve for x.
12x+19 + 22x - 9 = 180
34x + 10 = 180
34x = 180 - 10 = 170
x = 170/34 = 10/2 = 5
Where's the rest of the question?
