Answer:

C. 15 cm

Step-by-step explanation:

The equation for finding the hypotenuse is A squared + B squared = C squared.

Lets use 9 as A and 12 as B.

9 times 9 is 81. 12 times 12 is 144.

81 + 144 = 225.

The square root of 225 is 15.

The answer is C) 15 cm

What is the value of z so that -9 and 9 are both solutions of x^2+z=103?
Ira Lisetskai [31]
The answer is C.
x^2 + z = 103x^2 + 22 = 103*Subtract both sides by 22*x^2 + 22 - 22 = 103 - 22x^2 = 81*square root both sides to find x*√x^2 = <span>√81</span>
<span>x = +- 9</span>
