What is the value of z so that’s -9 and 9 are both solutions of x^2+z=103

we have been given that x=-9 and x=9 then putting two values of x in the given equation we can find the value of z. I've got the value of z as 22

Step-by-step explanation:

The given equation is :

x^2+z=103

If we put x as (-9) ,

(-9)^2+z = 103

or, 81 +z = 103

or, z= 103-81

or,z=22 (Answer)

Now , again if we put x as 9,

9^2+z=103

or, 81+z=103

or,z=103-81

or,z=22 (Answer)

THEREFORE THE VALUE OF Z IS 22

3x3 = 9 and 2x2 = 4

step-by-step explanation:

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
