Answer:

1 & 2 = Right Triangles

3 & 4 = Not Right Triangles

Step-by-step explanation:

Solved Using Pythagorean Theorem:

1) $9^{2} + 12^{2}$ = 225

$15^{2}$ = 225

2) $15^{2} + 36^{2}$ = 1521

$39^{2}$ = 1521

3) $10^{2} + 26^{2}$ = 776

$28^{2}$ = 784

4) $10^{2} + 12^{2}$ = 244

$16^{2}$ = 256

Tom and Lana were comparing their Halloween candy. Tom received 4 times as much candy as Lana received. Tom then split his candy

seropon [69]

Given that Lana received 18 ounces of candy and Tom received 4 times as much candy as Lana received, then the number of candy Tom received is given by 4(18) = 72.

Now, given that Tom divided his candy evenly into 9 piles. Then the number of ounces of candy in each of Tom's piles is given by:

72/9 = 8 ounces.

This graph shows the solution on a Cartesian plane.

Likely your graph is a solution on a number line. It will have an open circle at x=2, and an arrow pointing to the left from that point.
