Answer: Negative</h3>
======================================================
Explanation:
3/7 = 0.42857 approximately
Pick a number between that value and 5, not including either endpoint. Let's say we pick x = 2
Plug x = 2 into the f(x) function
f(x) = (x - 5)(2x + 7)(7x-3)
f(2) = (2 - 5)(2*2 + 7)(7*2-3)
f(2) = (2 - 5)(4 + 7)(14-3)
f(2) = (-3)(11)(11)
f(2) = -363
The actual result doesn't matter. All we're after is whether the result is positive or negative. We see the result is negative. This means f(x) is negative when 3/7 < x < 5. The f(x) curve is below the x axis on this interval.
On #29 x = 12 and <apb = 90° and <dcb = 40° and on #30 all I dont even understand, sorry
-86 = -6(-3p - 3) - 5p
Distribute the -6 into the parentheses:
-86 = (-6 * -3p) + (-6 * -3) - 5p
-86 = 18p + 18 - 5p
Simplify:
-86 = 13p + 18
Subtract both sides by 18:
-86 - 18 = 13p + 18 - 18
-104 = 13p
Divide both sides by 13:
= ![\frac{-104}{13}](https://tex.z-dn.net/?f=%5Cfrac%7B-104%7D%7B13%7D)
= ![\frac{-8}{1}](https://tex.z-dn.net/?f=%5Cfrac%7B-8%7D%7B1%7D)
<u>p = -8</u>

Good luck! If you have any questions, don't be afraid to ask :))
