Answer:
To complete the square, we need to have the equation set up like this:
x^2 +4x =9
To do that, we'd need to move the 4x to the left side producing
4x + x^2 = 9
And that can be rewritten as
x^2 +4x =9
So the term that needs to be moved is -4x

Answer:
B) 57.4+x=67
Step-by-step explanation:
We take the amount in the piggy bank. Then we take the amount spent and add it to the amount she has left. These two amounts should be equal
piggy bank = spent + left
67 = x + 57.40
You would do 80 * 6/10, which equals 48. Therefore there would be 48 sixth graders at the morning assembly. Hope this helps. Please rate, leave a thanks, and mark a brainliest answer(Not necessarily mine). Thanks, it really helps! :D
