An experiment is underway to test the effect of extreme temperatures on a newly developed liquid. Two hours into the experiment, the temperature of the liquid is -20°C. After 6 hours
of the experiment, the temperature of the liquid is -40°C. Assume that the temperature has
been changing at a constant cate throughout the experiment and will continue to do so. Write
an equation for the temperature of the liquid. How many hours into the experiment will the
temperature of the liquid be -100°C?

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

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

answer is  

a.

p = 78
