Final answer:
To find the length of the expression 6x+3+7.5x+10x-5, we need to simplify the expression by combining like terms. The simplified expression is 23.5x - 2.
Step-by-step explanation:
To find the length of the expression 6x+3+7.5x+10x-5, we need to simplify the expression by combining like terms. Adding the coefficients of the x terms, we get 6x+7.5x+10x = 23.5x. Adding the constant terms, we get 3-5 = -2.
Therefore, the simplified expression is 23.5x - 2. This is the length of the expression.
It is important to note that this expression represents the length and not the value of x. If you are given a specific value for x, you can substitute it into the expression to find the length.
