Answer:

Option A) $(-x^2 - 2x + 4)-(x^2 + 2x +1)= -2x^2-4x +3$ is modeled by the algebra tiles

Step-by-step explanation:

Given $(-x^2 - 2x + 4)-(x^2 + 2x +1)= -2x^2-4x + 3$

To verify that the given sum or difference is modeled by the algebra tiles

Now applying the algebraic sum operations we get

$(-x^2 - 2x + 4)-(x^2 + 2x +1)=-x^2 - 2x + 4 - x^2 - 2x -1$

$= -2x^2-4x + 3$ ( using algebraic sum operations )

Therefore $(-x^2 - 2x + 4)-(x^2 + 2x +1)=-2x^2-4x + 3$

Option A) $(-x^2 - 2x + 4)-(x^2 + 2x +1)=-2x^2-4x + 3$ is modeled by the algebra tiles

EXPLANATION

The given inequality is

$|x| \: > \: \frac{3}{2}$

This implies that,

$x\: > \: \frac{3}{2} \: or \: - x\: > \: \frac{3}{2}$

Multiply both sides of the second inequality by -1 and reverse the inequality sign.

$x\: > \: \frac{3}{2} \: or \: x\: < \: - \frac{3}{2}$

The graphical solution to this inequality is shown in the attachment.
