The perimeter is 2(length) + 2(width), so 2(x+5) + 2(x+4) = 42 m. In solving for x, you find 6. Plug 6 back into your length and width where x originally was, and you find your length to be 11m, and your width to be 10m. Hope this helps!
It is m + 9 because if we let m = 60 and the lest was 9 minutes longer than m, the test would be 69 minutes long. Therefore the answer is m + 9
We will use order of operations (PEMDAS) to solve this.
1.) 33+4(52-42) This is our equation. So, first we are gonna subtract 42 from 52.
2.) 33+4(10) Now that we did that, we are gonna add 4 to 33.
3.) 37(10) Lastly we are gonna multiply 37 by 10.
The answer is gonna be 370. If this helped, maybe consider giving me brainliest :)
