Can u help me with these math problems?

Question

I've been stuck on these probs for the last 3 weeks.

Solve for X:
3x^2 (3X Square) - 4X + 2

Write the following sentence as an "if.......then...." conditional. Then write its' inverse, converse, and contrapositive sentences. Identify each of the sentences as true or false.
ALL RECTANGLES ARE PARALLELOGRAMS.

A right triangle has legs of 14cm and 23 cm. Determine the degree measure of the angle opposite the 14cm leg.

PLEASE EXPLAIN HOW YOU GOT THE ANSWER.

the 1st one is 3x^2 - 8x + 2=0

Answer 1

1) is incomplete

You must have an equals sign to solve an equation.

Perhaps its a quadratic equation

3x^2 - 4x + 2 = 0

then solve by formula

Answer 2

3x^2 - 4X + 2 = 0
x = [4 +/- sqrt(16 - 4(3)(2)]/(2*3)
x = [4 +/- sqrt(-8)]/6
x = [4 +/- 2isqrt(2)]/6
x = 2/3 +/- i/3sqrt(2)
You have two complex roots

ALL RECTANGLES ARE PARALLELOGRAMS.
If it is a rectangle, then it is a parallellogram. (T) (If,then)
If it is a parallelogram then it is a rectangle. (F) (converse)
If it's not a rectangle, then it's is not a parallellogram (F) (inverse).
If it's not a parallelogram, it's not a rectangle (T) (contrapositive)

The hypotenuse is sqrt(14^2 + 23^2) = 26.93 cm
x = angle opposite 14 cm leg
x = arcsin 14/26.93 = 31.32 degrees.

Answer 3

If a figure is a rectangle then it is a parallelogram.
Converse: If a figure is a parallelogram then it is a rectangle.
Inverse: If a figure is not a rectangle then it is not a parallelogram.
Contrapositive: If a figure is not a parallelogram then it is not a rectangle
