H(x) = x^2 + 1 k(x) = x – 2<br> (h + k)(2)=?
likoan [24]
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:

ans: ii) 87° and iii) 60°

Step-by-step explanation:

ii)

y° = 180° - ( 56° + 37°)

missing angle on triangle is alternate angle of y° so are equal and sum of angles of triangle is 180°

iii)

x° + 2x° = 180°

sum of co interior angles is 180°

Slav-nsk [51]

Answer:

find out how many units higher g(x) is compared to f(x).

g(x) is 3 units higher than f(x)

Since the graph is 3 units higher, the value of k must be 3.

Step-by-step explanation:
