    10.3

    Step-by-step explanation:

    d = sqrt ((x2 - x1) ^2 + (y2 - y1) ^2)

    (7,-2) ... x1 = 7 and y1 = - 2

    (-2,3) ... x2 = - 2 and y2 = 3

    now we sub

    d = sqrt ((-2 - 7) ^2 + (3 - (-2) ^2)

    d = sqrt ((-9^2) + (5^2))

    d = sqrt (81 + 25)

    d = sqrt (106)

    d = 10.295 rounds to 10.3 <===
