A bird is standing on an electric transmission line carrying
3000 A of current. It is determined that the power dissipated
by the bird is 7.3 X 10-11 w. How many Joules of energy
does the bird dissipate per hour?

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

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.
