Measurement a is 45
measurement b is 135
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

You can factor -80 as

So, we have

The square root of a product is the product of the square roots:

Since
and
, we have

45 divided by 3= 15 then 15 times 4 =60 mph
