3 should be added to the tiles
Both expression have the same denominator: 9x²-1. Thus it must not be 0.
9x²-1=(3x-1)(3x+1)=0, resulting x=+-1/3.
Restrictions: x in R\{-1/3, 1/3}
Adding those expressions:
E=(-x-2)/(9x²-1 ) + (-5x+4)/(9x²-1)=
(-x-2-5x+4)/(9x²-1)=(-6x+2)/(9x²-1)=
(-2)(3x-1)/(9x²-1)=-2/(3x+1)
E=-2/(3x+1)
It could be PEMDAS.
That means solve by this order:
1). Parenthesis
2). Exponents
3). Multiplication
4). Division
5). Addition
6). Subtraction
To remember the order they say it like
this " Please Excuse My Dear Aunt Sally "
Answer:
50-(14+12+2(5)+2(2)+3)
50-(26+10+4+3)
50-43

Answer:
the answer would be 22 miles per gallon
Step-by-step explanation:
if we solve it as 330/15 since Kyle drove 330 miles on 15 gallons, our answer would end up being 22 miles per gallon
