Answer:

No real solution.

Step-by-step explanation:

Please find the attachment.

We have been given a function $2x^2+8=0$ . We are asked to find the solution for our given function by graphing method.

We can see that our given function is an upward parabola. We know that solution of parabola is points, where graph intersects x-axis.

We can see from our attachment that our given function never intersects x-axis, therefore, there is no real solution for our given function.

Simple...

you have: $\frac{18-2*5}{15+3(-3)}$

To solve this just go slowly..simplify everything out-->>

$\frac{18-2*5}{15+3(-3)} = \frac{18-10}{15+3(-3)}$

$\frac{18-10}{15+3(-3)} = \frac{8}{15+3(-3)}$

$\frac{8}{15+3(-3)} = \frac{8}{15+-9}$

$\frac{8}{15+-9} = \frac{8}{6}$

$\frac{8}{6} = \frac{4}{3}$

Answer is $\frac{4}{3}$ .

Thus, your answer.
