Answer:
-9y + 5x + 3
Step-by-step explanation:
-8y - (4x - 3) - y + 9x:
Group like terms = -(4x - 3) -8y - y + 9x
Add similar Elements - 8y - y + 9x = - (4x - 3) - 9y + 9x
Apply the distributive law: - (a - b) = -a + b = - (4x -3) = -4x + 3
= 4x + 3 - 9y + 9x
Group like terms = -9y - 4x + 9x + 3
Add similar Elements -4x + 9x = 5x
= -9y + 5x + 3
Step-by-step explanation:
use the identity a²-b²=(a-b)(a+b)
x²-4=(x-2)(x+2)
so the answer is x-2

.1 repeating is expressed as the fraction (1/9). So we are dealing with 72+ (1/9). As a mixed number, it is just 72 (1/9). To get an improper fraction, first multiple 9 by 72 (denominator times whole number) This is 648. Finally, add 1 (numerator). 649 is the resulting numerator of the improper fraction, 9 being the denominator (keep it the same). Divide 649/9 and you get 72.1111111
