So you follow PEMDAS
So we start with the exponent which is -X^2 so it would turn into X
Now we have X+4=10
We bring the four over and we get X=6
Hope this was helpful and ask questions if you still need help:)
The first one is 2x-3y/2
The second one is 1/x+2
The third one is (2x-5y)/(2x+5y)
The fourth one is x^2/z^2
5z^2 + 16
a coefficient is a number multiplied by a variable (a letter). so there is only ONE coefficient in this expression and it is 5.
It is 9 weeks. 8 times 12 is only 96$
