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

plz yuo

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
