Question A scientist needs 60 liters of a 40% solution of alcohol. He has a 30% solution and a 60% solution available.
How many liters of the 30% solution and how many liters of the 60% solution should he mix to make the 40% solution?
Provide your answer below:
30% solution:
liters,
60% solution
liters

a

step-by-step explanation:

u take $30 minus $24. the answer/original($30)

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
