Answer: (C) divide by 1
<u>Step-by-step explanation:</u>
when dividing by x - 1, set the expression equal to zero to find the zero. That is actually what you are dividing by:
x - 1 = 0 ⇒ x = 1
so the number outside of the synthetic division symbol is 1.
Answer: F
Step-by-step explanation:
This is basically like 2 rectangles. Find the area of both and add them together.
Remember that the area is x .
Area of Rectangle 1: = 7, = 14
14 x 7 = 98
Area of Rectangle 2: = 5, = 14
14 x 5 = 70
Add the areas together: 98 + 70 = 168
Answer:
512 student tickets.
Step-by-step explanation:
Let x be number of student tickets and y be number of adult tickets.
We have been given that at Friday's football game 1,294 tickets were sold. We can represent this information as:
