The answer to your question is 46.9
Answer:
Both of the points are in the same x-axis (which is 4). However, they are different because one of them is shifted 9 units up and the other one is shifted 9 units down (their y-axis are different). Their quadrants are also different since (4,9) is at the first quadrant, while (4,-9) is at the fourth quadrant.
So the rule with multiplying exponents of the same base is to add the exponents together. Applying this rule here would look like this:

In short, your simplified expression is going to be -16x^7y^6.
C. carbon is found in all living things
a. heat is trapped in carbon
Sum. To build the triangle, start with 1 at the top, then continue placing numbers below it in a triangular pattern. Each number is the numbers directly above it added together.
