If 3/4 and 12/r are equivalent, what is the value of x?

r = 16

Step-by-step explanation:

I think you mean r not x.

3/4 times ? = 12/r

3/4 times 4 = 12/r

4 times 4 = 16

3/4 times 4 = 12/16

The value of x is 16.

Step-by-step explanation:

Given data:

3/4 = 12/r

The value of x = ?

Solution:

3/4 = 12/r

By multiplying 4 on both sides of equation:

= 3/4 × 4 = 12/r × 4

= 3 = 48/r

By cross multiplication:

= 3r = 48

By dividing 3 on both sides:

= 3r/3 = 48/3

= r = 16

The value of x = 16

Explanation:

Here the value of x means the value of r. Because in equation r is unknown and in general mathematics x means an unknown value.

So by simplifying and solving the equation, r is equal to 16. And consequently x is equal to 16.

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
