Answer:
The LCM of 40 and 5 is simply 40.
Step-by-step explanation:
To find the lowest common multiple of any 2 numbers, we will first list the prime factors of each number.
40: 2 × 2 × 2 × 5
5: 5
Then we need to multiply each factor the most amount of times it appears in either number.
2: 3 times in the first number
5: 1 time in either number
Now we multiply these.
2 × 2 × 2 × 5 = 40
The LCM of 40 and 5 is simply 40.
Answer: The paper, scissors, pencils, stickers, and paint belong on the top shelf of the craft closet.
Explanation: When you are listing items, you need to place a comma in between them. The comma in between the “stickers” and “and” is the Oxford comma. When you lost multiple items, you need a comma after the word before “and”.
Answer:
A = 2x²-3x-5
Step-by-step explanation:
Given that,
The length of the bedroom, l = (2x-5)
Width of the bedroom, b = (x+1)
We need to find an equation for the area of the bedroom. We know that,
Area of a rectangle = lb
Put all the values,
A = (2x-5)(x+1)
= 2x²+2x-5x-5
= 2x²-3x-5
Hence, the area of the bedroom is equal to 2x²-3x-5.
Answer:
ok imma be honest i dont have a clue jk
Step-by-step explanation:
use a calculator
Answer:
x=30o+n90on∈Z
Step-by-step explanation:
cos2x=sin(90o−2x)=sin(2x−30o)
Which mean 90o−2x=2x−30o+n360o
or 90o−2x+2x−30o=(2n+1)180o
The later cannot be true.
so x=30o+n90on∈Z
