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:
14%
Step-by-step explanation:
To get the percent increase divide 0.8 by 0.7
0.8/0.7 ≈ 1.14285714286
So the percent increase would by about 14 percent
5x - 2 equivalent to to 2x−2+3x
answer is B. 2x−2+3x
I'm glad to hear that, but where is the math problem?
14 because i did the math and i was right
