Answer:

<em>Distance = </em>\sqrt{113}<em />

Step-by-step explanation:

(1, 5) = (x_1,y_1)\\ (-7, -2)=(x_2,y_2)\\\\d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\ \\d = \sqrt{(-7-1)^2+(-2-5)^2}\\ \\d = \sqrt{(-8)^2+(-7)^2}\\ \\d = \sqrt{64+49}\\ \\d = \sqrt{113} \\\\

Answer:\sqrt{113}

Step-by-step explanation:

Distance formula: \sqrt{(x2-x1)^2+(y2-y1)^2}

x1=1     x2=-7     y1=5     y2=-2

----------------------------------------------------------------

 \sqrt{(-7-1)^2+(-2-5)^2}

=\sqrt{(-8)^2+(-7)^2}

=\sqrt{64+49}

=\sqrt{113}

Hope this helps!! :)

Step-by-step explanation:

f(3) =  {(3)}^{2}  + 3(3) - 7 = 9 + 9 - 7 \\  = 18 -  7 = 11

g(3) = 5(3) - 3 = 15 - 3 = 12

f(3) + g(3) = 11 + 12 = 23
