2x 2 - 4x + 6 = 0 is in general form.

2x² - 4x + 6 = 0 /:2

x²-2x+3=0

Δ=(-2)²-4·1·3=4-12=-8<0

x∈∅

False. A, B, and C does not have a greatest common factor of 1 which means this ewuation is not in general form.

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

$2416.6

step-by-step explanation:

per hour = $ 25

total work time = 35

commission = 15%

total she has to make = $ 4,500

let she sold x dollar products

so her commission will be 15 % of x

now

total = weekly basic pay + commission

4500= (25*35) + 15 % of x

4500=875 + * x

4500-875 =   * x

3625= * x

multiplying wwith 100 on both sides gives

36250 = 15 x

now

x =  

x= $2416.6
