17 or 289

(-5,8) to (3,-7)

Step-by-step explanation:

Find the difference between coordinates:

(x2-x1) = (3 - -5) = 8

(y2-y1) = (-7 - 8) = -15

Square the results and sum them up:

(8)2 + (-15)2 = 64 + 225 = 289

Now Find the square root and that's your result:

Exact solution: √289 = 17

Approximate solution: 17

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
