Translated
so the distance from A to A' should be the same as form B to B'

distance formula
distance between (x1,y1) and (x2,y2) is
D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

so distance between (1,5) and (-2,1) is
D=\sqrt{(-2-1)^2+(1-5)^2}
D=\sqrt{(-3)^2+(-4)^2}
D=\sqrt{9+16}
D=\sqrt{25}
D=5

the distance is 5 units

Answer:

Step-by-step explanation:

1. 6*6 + 6*12

= 36 + 72

= 108.

2. 3*5 + 3*5 + 3*14

= 15 + 15 + 42.

= 72.

3.  10*4 + 1/2 * 4*4

= 40 + 8

= 48.

4. 12*6 + 1/2 * 12 * 3

= 72 + 18 = 90.

Oksi-84 [34.3K]

Answer:

$750

Step-by-step explanation:

Larger share = $450

Smaller share : Larger share :: 2 : 3

Smaller share = (larger share x 2) / 3

= 300

Sum= larger share + smaller share

= $450 + $300 = $750
