The large triangle & the small one are similar, since their respective bases are parallel. Then we can write:

(8+6)/6 = x/7. and 14/6 = x/7 or 7/3 = x/7 . Cross multiplication:

7/3 = x/7 → 3x = 49 → x = 49/3 → x = 16.3 (Answer D)

For what values of $x$ is it true that $x^2 - 5x - 4 \le 10$? Express your answer in interval notation.

dybincka [34]

Answer:

x ∈ [-2, 7]

Step-by-step explanation:

The given equation ...

x^2 -5x -4 ≤ 10

can be rewritten as ...

x^2 -5x -14 ≤ 0

and factored as ...

(x +2)(x -7) ≤ 0

Clearly, the "or equal to" condition will be met when x=-2 and x=7. For values of x between these numbers, one factor is negative and the other is positive. Hence the product will be negative. So, numbers in that interval are the solution set.

x ∈ [-2, 7]

This can be shown if you do 3 milligrams per kilogram the person weighs.

So if the person weighs 80 kilograms, you do 80*3 to get 240 milligrams.
