Melanie said: 
Every angle bisector in a triangle bisects the opposite side perpendicularly.

A 'counterexample' would show an angle bisector in a triangle that DOESN'T
bisect the opposite side perpendicularly.

See my attached drawing of a counterexample.

Both of the triangles that Melanie examined have equal sides on both sides
of the angle bisector.  That's the only way that the angle bisector can bisect
the opposite side perpendicularly.  Melanie didn't examine enough different
triangles.

What is the chance of drawing a yellow ball then a red ball from a bag containing 3 yellow balls and 7 red balls?
Ainat [17]
Talking as if the balls do not get put back into the bag, the first probability is 3/10 for yellow. For red it will be 7/9 because there is one less ball (yellow) in the bag.

joja [24]

Answer: 6x² + 36x + 22

Step-by-step explanation:2 faces  (x + 3) by (x + 7), area of both these faces 2(x+3)*(x + 7)

2 faces  (x + 3) by (x - 1), area of both these faces 2(x+3)*(x - 1)

2 faces  (x -1 ) by (x + 7), area of both these faces 2(x-1)*(x + 7)

Whole surface area is

2(x+3)*(x + 7) + 2(x+3)*(x - 1) + 2(x-1)*(x + 7) =

=2(x² + 3x +7x +21) + 2(x² +3x -x - 3) + 2(x² - x +7x -7)=

=2x² + 20x +42 + 2x² + 4x - 6 + 2x² + 12x -14 =

= 6x² + 36x + 22

4) Crystal wants to buy the newest iPhone XS Max that costs $1200.
irina1246 [14]

Answer:

8.75%

Step-by-step explanation:

If she pays $135 eight times then she pays a total of 135 x 8 = $1080.

She had a down payment of $225, so that added on becomes $1305.

1305/1200 is 1.0875, which is an increase of 0.0875 over the original.

0.0875 x 100 = 8.75% increase.
