Answer:
(2x + y)(2x - y - 1)
Step-by-step explanation:
4x² - y² - 2x - y
4x² - y² is a difference of squares and factors in general as
a² - b² = (a - b)(a + b) , then
4x² - y²
= (2x)² - y²
= (2x - y)(2x + y)
expression is now
(2x - y)(2x + y) - (2x + y) ← factor out (2x + y) from each term
= (2x + y)(2x - y - 1)
86/7 = 12.28 days worth
so they will run out on the 13th day of the next month
55 increased by 209%
Since we are increasing by 209% ,
New value would be = 100% + 209% = 309% of the old value which is 55.
= 309% * 55
= (309/100) * 55
= 3.09 * 55 = 169.95
The result is 169.95
