Arecipe calls for 1 3/4 cups of flour. if the recipe is tripled , how much flour is needed.

cups flour

Step-by-step explanation:

A recipe calls for amount of flour =   cups

                                                       = cups

If the recipe is tripled this means if the recipe becomes 3 times in amount.

Flour is needed = × 3

                          =

                          =

                          = cups

cups flour is needed.

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

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
