(56/7)*(42/7)= how do you solve this problem can someone explain it to me

To multiply fractions, multiply straight across. Multiply the numerators and the denominators. Multiply 56 times 42 and 7 times 7.

You can simplify 2352/49 even more by dividing 2352 by 49. 2352/49 = 48, so your answer is 48.

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
