4x²y + 24x² - 24y - 144 can be written as :
4x²(y + 6) - 24(y + 6)
(y + 6)(4x² - 24)
(y + 6) is the factor of 4x²y + 24x² - 24y - 144
Answer:
Step-by-step explanation:
The absolute value of an integer is the distance that separates the number from the zero position "0", that is, the absolute value of an integer is the natural number that results from suppressing its sign.
In other words, the absolute value of a real number a, written |a|, is the same number a when it is positive or zero, and opposite of a, if a is negative.
In this case IxI>= 3 means that 
This is translated as, since the absolute value of x represents the distance from zero, the solutions to this inequality are those numbers whose distances from zero are greater than or equal to 3, that is, that x is greater than or equal to 3 or x is less than or equal to -3.
Answer: 92 and 94
Step-by-step explanation:
x = first number
x + 2 = second number
x + x + 2 = 186
simplify
2x + 2 = 186
subtract 2 from both sides
2x = 184
divide both sides by 2
x = 92
92 + 2 = 94
The numbers are 92 and 94.
Answer:
7.15 hours or 7 hours 9 minutes.
Step-by-step explanation:
Time = distance / average speed.
= 715 / 100
= 7.15 hours.
