Answer:
C.
Step-by-step explanation:
In a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
A.
9 + 9 = 18
18 < 22
No triangle
B.
7 + 3 = 10
10 = 10
No triangle
C.
5 + 6 = 11 and 11 > 9 good
5 + 9 = 14 and 14 > 6 good
9 + 6 = 15 and 15 > 5 good
There is a triangle.
Answer: C.
Ok so we have
1 cup of mix=2 cups of water
you can make one of 2 assumptions
1. the mix disolves in the water and doesn't take up space (if so go to AAAAAAAAAAAA)
2. the mix doesn't disolve and takes up space (if so go to BBBBBBBBB)
AAAAAAAAAAA
so since the mix doesn't take up space, the pitcher volume=water volume
pitcher volume=20
water volume=20
mix=1/2 of water volume
mix=1/2 of 20
mix=1/2 times 20
mix=10 cups
BBBBBBBBBBBBBB
if the mix does take space
1:2
we add them
1+2=3
3 cups is 1 unit of mix and water
how many 3's are in 20
20/3=6 and 2/3 cups
so
mix=1 unit=6 and 2/3 cups
water=2 unit=2 times 6 and 2/3=13 and 1/3
water=13 and 1/3 cup
mix=6 and 2/3 cup
depends on which assumption you make
if AAAAAAAA
mix=10 cups
if BBBBBBBBB
water=13 and 1/3 cup
mix=6 and 2/3 cup
Answer:
2
Step-by-step explanation:
I am 100% sure
Answer:
i think it is 3
Step-by-step explanation:
Basically expand
use FOIL (a way to remember distributive property)
first outer inner last
that is th eorder to multiply them
First: x times 2x=2x²
Outer: x tmes 9=9x
Inner: -8 times 2=-16x
last: -8 times 9=-72
add them
2x²+9x-16x-72
2x²-7x-72
