Answer:
4 and -7
Step-by-step explanation:
a coefficient is a number that is being multiplied with a variable (ex:5a) in this case the coefficients are 4 and -7
The distance formula is:

We are given two points in the form (x,y), so plug in the values to the distance formula:

Next we can simplify. We know that 12-12 is 0, so we can drop it from the equation, as it will not affect our answer. Also, we know that -10-15 is -25:

The square and square root cancel each other out leaving us with 25.
The answer is 25.
Answer: b: h=2a/b1+b2
Step-by-step explanation:
Step 1: Create Equation: 12+15+x=55
Step 2: Solve it: you will get x=28
Step 3: You could check it by plugging your answer in.
Hope that helps!!!
