7/3
Step-by-step explanation:
(7-0)/(9-6)
Answer:
x = approx. 1.24 or -7.24
Step-by-step explanation:
It's hard to factor directly so we should use the quadratic formula or complete the square. I'm going to go with completing the square.
x²+6x-9=0
x²+6x=9
x²+6x is the same as x²+2·3·x, in order to make this into the algebraic identity (A+B)²=A²+2AB+B², we must add B², or in this case 3² to both sides. (A is x, B is 3)
x²+6x+9=18
(x+3)²= 18
x+3= ±√18
x= ±4.24 -3 (approximately 4.24)
First solution for x = 4.24-3 = 1.24
Second solution for x = -4.24-3 = -7.24
You'd do the same as in
brainly.com/question/2700999lemme hmmm redo the fractions... and as I said, you flip them around as needed
notice, we flipped them some, so the unit ends either above or below
in order to cancel the one on the left
It would take you 20 minutes to walk 2 kilometers, because one kilometer is 1000 meters. 2 kilometers would be 2000 meters, and 2000 divided by 100 is 20.
