The missing value is 3255
Explanation:
Parentheses can be eliminated using the distributive property
-6x +6(3x -4xy) = -6x +18x -24xy
Like terms (those with the variable x only) can be combined
x(-6+18) -24xy = 12x -24xy . . . . . simplified
_____
In some cases, you may be interested in factoring the expression. 12x is a common factor for the two terms, so another way to write this expression is
... 12x(1 -2y)
Answer:
x = -1.791 and x = 2.791
Step-by-step explanation:
Answer:
interquartile range=21.05
Step-by-step explanation:
3.5, 12, 19.1, 25.8, 31.8
median is 19.1
Quartile 1= (3.5+12)/2=7.75
Quartile 3=(25.8+31.8)/2=28.8
interquartile range=Q3-Q1=28.8-7.75= 21.05
Answer:
1. No
2. yes
3. yes
4. yes
Step-by-step explanation:
1. 2×3=6, 7×3=21 (The product of two (or more) prime numbers cannot result in another prime number. By definition, a prime number is a number that is divisible by 1 or itself - multiplying two or more primes together will always yield a number divisible by 1, itself and the prime numbers multiplied together to achieve it.
2.When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.
3. 1×3=3, 3×5=15 (odd numbers are not divisible by 2)Therefore, every prime number other than 2 is an odd number
4. 2×4=8, 6×8=48
