Kala bought two types of cheese at a deli. she bought 0.50 pound of american cheese and 1.25 pounds of swiss cheese. the bar diagram and equation below represent kala’s purchase, where p represents the total number of pounds of cheese she bought. what is the total number of pounds of cheese kala bought? 0.75 1.20 1.30 1.75

The total number of pounds of cheese Kala bought is 1.75 pounds

Step-by-step explanation:

Kala bought two types of cheese at a deli.

She bought 0.50 pound of American cheese and 1.25 pounds of Swiss cheese.

The total number of pounds of cheese Kala bought

= 0.50+1.25

= 1.75 pounds

Hence,  the total number of pounds of cheese Kala bought is:

  1.75 pounds

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
