Answer:
For the question below, you will need to find the GCF of 45 and 60. In this instance it is 5, so it will be outside the box. The GCF answers will be inside the parenthesis, which is 7 and 12.
45x + 60 = 5(7x + 12)
In this question you have to multiply 2 with every number inside the parenthesis. So 2 × 10x and 2 × 4.
2(10x+4) = 20x + 8
Hope this helped.
Answer:
The coordinates of C is (-8,1)
Step-by-step explanation:
Looking at the attached image, you'd see that, AB is 1 and BC is 1, that's because we are told that ratio of AB to AC is 1:2 meaning, AC is 2 and AB is 1. Therefore for that ratio to be satisfied BC has to be 1 so that AC would be 2.
Now let's assume the coordinates of C is
.
To get it's coordinates, we use the section formula:

Where (m,n) is the (AB, BC)
Therefore we have

This gives:

and 
From there x = -8 and y = 1
Therefore the coordinates of C is (-8, 1).
A. The answer is 494.6 rounded.
b. She most likely did not add 417.62 to 76.9
B). 10.63
Because 7^2=49 and 8^2=64 then 49+64=113 then the square root of 113 is 10.63
