The temperature of water that was boiled as it is left in a room at room temperature over a period of time.
2(x + y) + 3(x + y)
first distribute:
(multiply 2 into everything in the first parenthesis, and 3 into everything in the second)
2x + 2y + 3x + 3y
Second simplify (add all like terms (adding in this case) )
(2x + 3x) + (2y +3y)
5x + 5y
your answer is: 5x + 5y
hope this helps
To compare, you have to make the fraction/mixed number into decimals
6&4/9=6.4444444444444
127/20=6.35
every decimal has a whole of 6, so you need to look at the tenth's place, 4 is obviously larger than 3, so 6&4/9 is the largest.
the other three numbers all have a 3 in its tenth's place, so look at the hundredth's place, 9 is larger than 7, and 7 is larger than 5
so from the least to the largest:
127/20, 6.375, 6.39. 6&4/9
Answer:
Approximately 32 in
Step-by-step explanation:
This is a Pythagorean Theorem problem: we have the hypotenuse (diagonal size) and the leg (width). Now solve for the height.
a^2 + b^2 = c^2
56.7^2 + b^2 = 65^2
b^2 = 1010.11
<u>b = 31.78 in ≈ 32 in</u>
Answer:
There are six equilateral triangles in regular hexagons
