Question

Evaluate x^2/y + x^2/z, if x=10, y=-5, and z=-2

Answer 1

Hi Jasmine

x²/y + x²/z
if x = 10, y=-5 , z = -2
Evaluate x, y,z
10^2/-5 + 10^2/-2
10²/-5 + 10²/-2
- 70

I hope that's help !

Answer 2

The answer is -70.

Explanation:

In order to determine the answer, we have to know about "replacing variables". In any expression which contains variables, we can replace them by values to get different results.

So, in this case, we have the variables "x", "y" and "z", and also we have the values to replace every variable.

Replacing those values:

`(x^2)/(y)+(x^2)/(z)\\ \\x=10\\y=-5\\z=-2\\\\((10)^2)/((-5))+((10)^2)/((-2))\\ (100)/((-5))+(100)/((-2))\\ -20-50\\-70`

Finally, the value of the expression is -70.
