I think is A ,it's true use a calculator!
Solution:
<u>We know that:</u>
- Given diagonals: LN and MP
- LN and MP must be equal because they are diagonals of LMNP.
- LN = 4x + 3
- MP = 8x - 9
<em>Since LN and MP must be equation</em>, <u>equation formed:</u> 4x + 3 = 8x - 9
<em>Let's simplify the equation to find x.</em>
<u>Subtracting 4x both sides.</u>
<u>Add 9 both sides.</u>
<u>Divide 4 both sides.</u>
<em>Now, let's find the length of each diagonal.</em>

<span>42x^3+21x^2-35x divided by 7x comes out to
42x^3 21x^2 35x
-------- + --------- - --------
7x 7x 7x
Reducing these 3 fractions, we get 6x^2 + 3x - 5 (answer)</span>
