Answer:

8x² + 14x - 15

Step-by-step explanation:

(2x + 5)(4x - 3)

Each term in the second factor is multiplied by each term in the first factor, that is

2x(4x - 3) + 5(4x - 3) ← distribute both parenthesis

= 8x² - 6x + 20x - 15 ← collect like terms

= 8x² + 14x - 15

The limit does not exist. There are infinitely many infinite discontinuities at $x=n\pi$ , where $n\in\Bbb N$ . The function oscillates wildly between negative and positive infinity.

E is the midpoint of Df, DE=2x+4, and EF=3x-1. Find all segment lengths

sertanlavr [38]

If E is the midpoint, DE and EF are equivalent.
2x+4=3x-1
4=x-1
5=x

Plug the value of x in
2(5)+4
14

3(5)-1
14

14+14=28

Final answer: DE=14, EF=14, DF= 28
