The perimeter is 4x + 14
1.) 3x - 5 + 2x + 19 - x
2.) look for like terms: 3x<em> </em><u>- 5</u> + 2x <u>+ 19</u><em> </em>- x
3.) simplify 3x + 2x - x = 4x -5 + 19 = 14
so the answer is 4x + 14
The profit of the concession is $350.
<h3>
What specifically are expressions?</h3>
- A group of numbers or variables combined with the operations +, -, ×, or ÷ form an expression.
- While algebraic expressions include variables, numbers, and mathematical operators, arithmetic expressions only contain numbers and mathematical operators.
- Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression.
- In the expression 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.
So, c - e:
Substitute the values in the expression:
Therefore, the profit of the concession is $350.
