Answer:
<h2>8(u + 3) = 8u + 24</h2>
Step-by-step explanation:
She walked 7 miles. If it takes her one hour to walk four miles, then it will take 45 minutes to walk 3 miles.
<span>f(x)=(x^2 -2x)(3x-1) is a product and is most easily differentiated using the product rule:
f '(x) = (x^2 - 2x)(3) + (3x-1)(2x-2)
Now subst. 2 for x in this equation. We get:
f '(2) = (2^2 - 2(2))*3 + (3(2)-1)(2(2) -2), or
=3(4-4) + (6-1)(2) so f '(2) = 10 (answer)</span>
