Step-by-step explanation:

7h=-(2h-18)

*EXPAND -(2h-18) : -2h+18

7h=-2h+18

*ADD 2H TO BOTH SIDES

9h=18

*DIVIDE BOTH SIDES BY 9

h=2

answer: i think it is (1,-2)

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
