Answer:
D
Step-by-step explanation:
I think...this is a really hard question but D is the one I would choose. Forgive me if I'm wrong
A perfect square trinominal is the square of a binomial. Perfect square trinomials are in the form
a^2 + 2ab + b^2
or
a^2 - 2ab + b^2
Looking at the options, first check the leading term is a perfect square. They all are so we can’t eliminate anything. Next we check if the last term is a positive perfect square. The third option is not positive so we can eliminate that one.
Finally we check the center term. The first one does not have a middle term so we can eliminate that one.
The center term must be 2 times the square root of the first times the square root of the last.
The second option - square root of first term is 2m, square root of last term is 3n. 2*2m*3n is 12mn. That is not the middle term so the second option is not right.
The last option - square root of first term is 4x, square root of last term is 3y. 2*4x*3y is 24xy. That is the middle term. So the last option is the correct answer.
It’s 855 sike I lied thanks hope it help !
This is already in scientific notation
168/5 you take 25 1/4 divided by 3/4= 36.6= 336/10 simply = 168/5 or 33 3/5
