Find the number 2/3 of it is 30

45

Step-by-step explanation:

Of means multiply and is means equals

2/3 *x = 30

Multiply each side by 3/2

3/2 * 2/3 *x = 30 * 3/2

x = 90/2

x = 45

45

Step-by-step explanation:

2/3 of a number is 30

divide 30 by 2 to get 1/3

15 is 1/3

no times it by 3 to get 3/3

45

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
