Question

If x =2 y=3 z=4 solve the following x² + y²

Answer 1

Step-by-step explanation:

$x = 2$

$y = 3$

$= {x}^{2} + {y}^{2}$

$= (2 {)}^{2} + (3 {)}^{2}$

$= 4 + 9$

$= 13...$

...

Answer 2

Answer:

13

Step-by-step explanation:

Given x = 2, y = 3 and z = 4. We'll evaluate the value of x² + y² with given condition.

First, remind that we are only given the expression of x-term and y-term only and therefore, z-term is not included - it's not to be considered.

Substitute x = 2 and y = 3 in the expression:

$\displaystyle{2^2+3^2 = 4+9}\\\\\displaystyle{4+9 = 13}$

Hence, the value of x² + y² when x = 2 and y = 3 is 13.
