It is estimated that each guest at a party will eat 4/9 pounds of chocolates. How many guest can be served It is estimated that each guest at a party will eat
with 12 pounds of chocolate?

you can serve 27 guest.

Step-by-step explanation:

if one guest eat 4/9 pound. the we need to find with how many guest it will reach 12 pounds.

that's is how many times of 4/9.

4x/9 = 12

4x = 108; x = 27.

if you multiply 27 with 4/9 you get 12. this means that if all 27 people, if they eat 4/9 pound of chocolate they will eat 12 pounds in total.

step-by-step explanation:

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
