Answer:
177 and 178
Step-by-step explanation:
First, the expression for the 2nd mile marker is x+1.
Now, you add x and x + 1 together to get 2x + 1
Next, make 2x + 1 equal to 355
Now subtract 1 and then divide by two on both sides to get x = 177.
This means that the first mile marker is 177 and the next is 178.
Answer:
12 + 29x - 14
Step-by-step explanation:
(3x+2)(4x-7)
Multiply out 3x first then 2
(3x * 4x) - (3x * -7) + (2 * 4x) + (2 * -7)
12 - (- 21x) + 8x + ( -14)
12 + 21x + 8x - 14 Combine like terms
12 + 29x - 14
210 : 65
