Answer:

5x^3 + 16x - 2y^3

Step-by-step explanation:

7x + y^3 + 7x^3 + 6x - 3y^3 - 2x^3 + 3x

group like terms

= 7x^3 - 2x^3 + 7x + 6x + 3x + y^3 - 3y^3

add similar items

= 5x^3 + 7x + 6x + 3x + y^3 - 3y^3

add similar items

= 5x^3 + 16x + y^3 - 3y^3

add similar items

= 5x^3 + 16x - 2y^3

<h2><u>Solution</u>:-</h2>

Hypotenuse (x) of the right triangle = $\sqrt{7² \: + \: 11²}$

Hypotenuse (x) of the right triangle = $\sqrt{49 \: + \: 121}$

Hypotenuse (x) of the right triangle = $\sqrt{170}$

Hypotenuse (x) of the right triangle = 13

The hypotenuse (x) of the right triangle is <u>1</u><u>3</u><u> </u><u>m</u>.
