The answer is A that part is hard in math
$8.25x2=$16.50
$5x2=$10
$10+$16.50=$26.50
2x$20=$40
$40-$26.50=$13.50

Answer:
Step-by-step explanation:
Givens
x2 = 5
x1 = - 1
y2 = 8
y1 = 6
Equation
d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )
Solution
d = sqrt( (5 - - 1)^2 + (8 - 6)^2 )
d = sqrt( 36 + 4)
d = sqrt(40)
d = 2 * sqrt(10)
