Use www.wolframalpha.com or if you really wanna finish your work quickly, use Mathematica.

I know this is trigonometry but i cant figure this one out
There are two triangles in the problem. The hypotenuse in one of them is 92m long and in the other one it's (92 + 54) 146m. Since they both contain a ninety degree angle the triangles are similar in shape (but not size). To find the value of x we need to find the value of the "similar side" on the other triangle, which is 23m. We need to check how much larger the triangle with the x is than the other one. We can do this by simply dividing 146 by 92, and we get 1.58(...) Now, to find the value of x simply multiply 23 by the previous number (1.58...). The number you get from doing this is 36.5, which is your final answer (x = 36.5m). We can also set it up like this: 92/146 = 23/x.
Hope this helped!

I'd recommend trying to solve these things on your own to help you when you get to factoring, parabolas, Pascal's triangle, hyperboles, and all that annoying stuff in Algebra.

I'll help you with the first one, but I won't give answers.
9x - 5 = 2x + 8
Then
7x = 13
Then you can solve for x.
For question c and d, use distributive property
For question e, multiply by 5 and then multiply by x and then solve, or you can use cross multiplication

These are pretty much the most basic questions you'll get in algebra
I wish my homework was as easy as this
Also fix your swimming pool surface area

IKR! I have much harder stuff and i'm only 12 years old!
Like graphing, tables, slopes...grrr(so jealous)

Yeah, just realized that one isn't correct either.

That's basic math. 1st pic: Put Xs right and numbers left by changing + to - (for example 2X becomes -2X when you put it on the right side). After that calculate the results.
The third pic is correct.
I've never done something similar to the 2nd pic, so I can't help you with that.
