Okay. I used to struggle with this one too sweetie. First off, you are using multiplication, when two numbers are close together it means they need to be multiplied. You are also using addition which means you can add the exponents together. In this case, it would equal x to the power of nine. Then add 12 and 35 which equals 47. So the equation is 47 multiplied by x to the power of nine.
Answer:
n=14
Step-by-step explanation:
To find the length of the given side with length "n", we must know the relationship between the different sections when the chords cross one another.
Now, the relationship we require is that when we multiply the 2 parts of both chords together, it will be equal to the product of the two sides in the other chord. Thus;
7(8) = 4(n)
56 = 4n
14 = n
