Answer:
3/5 3/2
Step-by-step explanation:
6 Green and 9 Red
13,200
because you would take 165,000 and mulitply it by .08 (because it is a percent just move the decimal 2 places to the left to get it in decimal form) which would then give you 13,200
Answer:
x(2x-5)(x+1)
Step-by-step explanation:
1. First factor out the x of all the numbers to get x( 2x^2 -3x -5)
2. To factor, I used cross multiplying- (Sorry but I don't know how to explain it)
3. You're done!
(Sorry if it isn't amazing)
Answer:
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
