Mrs. Meyette and Mr. Reincke went out of town to pick pumpkins. Mrs. Meyette picked 12 pumpkins each weighing 1.45 pounds and Mr. Reincke picked 23 pumpkins each weighing 2.01 pounds. What was the combined weight of all the pumpkins Mrs. Meyette and Mr. Reincke picked together?

63.63 lbs

Step-by-step explanation:

12 * 1.45 = 17.4

23 * = 46.23

17.4 + 46.23 = 63.63

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
