The third option: uses visual representation of the logical...
First we will compute the h+k and then multiply the result by 2.
To add polynomials, we add terms whose variables are alike, for example:
we add the coefficients of x^2 together, the coefficients of x together and so on.
Therefore:
h + k = x^2 + 1 + x - 2 = x^2+x-1
Now, we will multiply this answer by 2 to get the final answer:
2(h+k) = 2(x^2+x-1) = 2x^2 + 2x -2
Answer: -3
Step-by-step explanation:
It could be seen from the table that when x is 2, the y value is 0. Thus, it can be concluded that the x intercept is (2,0)
The correct answer is B
It will be 69 because 68 is wrong and 69 is right
