15 = 5 + 8d - 12
15 = 8d - 7
15 + 7 = 8d
22 = 8d
d = 2.75

Answer:

It is possible, because the two shortest sides have to add up to be more than the longest side, and 8 + 12 = 20, which is more than the longest side of 17.

So yes, I agree with Bear.

Question: if Cory walks 3 units south and 4 units east, what would his new coordinate be?
maks197457 [2]

Answer:

(5,-2).

_______________________

South is Negative Y axis.

East is Positive X axis.

(look at the compass in the top right corner)

Cory's current coordinates are (1,1).

When Cory walks 3 units south, he moves 3 steps downwards in the Y axis, which means if his current Y position is 1, we subtract 3, ( 1 - 3 = -2).

And when Cory moves 4 units east, Add 4 as he is walking in the positive X axis. (4 + 1 = 5).

new (x,y) are (5,-2).
