Which of the following is equivalent to 18 + 36?
a 29+16)
6/3 + 12)
7(2+4)
2+36)

None.

Step-by-step explanation:

18+36=54

A) 29+16=45

B) 6/3+12=2+12=14

C) 7(2+4)=7(6)=42

D) 2+36=38

up

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.
