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:
36
Step-by-step explanation:
If you set the equation up, it would be n + 5 = 41. If you subtract the 5 from both sides to get n by itself, you get n = 36.
The bottom 2 i’m pretty sure, sorrry if it’s wrong
Answer:
from now on don't ask same qn two times or more it would be waste of your points
got it??
Answer:
24
Step-by-step explanation:
use Pythagoras theorem
a^2 + b^2 = c^2
18^2+b^2=30^2
b^2 = 30^2 - 18^2
b = √576 =24
