Mathematics

Chad's claim is incorrect

Step-by-step explanation:

The homework problems that complete the question are:

3x^2.2x^4

5 - 2x = 3x

3(2x + 7)

7x^2 +2x -3x^2 -9

$\frac{2}{3} = \frac{x+2}{6}$

Required

Is Char right?

From the homework problems above, there are 5 mathematical problems

So:

Chad's claim that he had 5 equations.

A mathematical expression is an equation if it has an = sign

So for Chad's claim to be correct; at least 4 of the mathematical problems must have an = sign

By the explanation done above, we have the following observations

3x^2.2x^4 -> No Equation

5 - 2x = 3x -> Equation

3(2x + 7) -> No Equation

7x^2 +2x -3x^2 -9 -> No Equation

$\frac{2}{3} = \frac{x+2}{6}$ -> Equation

Apparently, only 2 of the 5 problems are equation.

Hence, Chad's claim is incorrect.
