When simplified:
8x^2-8+3x^2+6x
= 11x^2+6x-8

Therefore, the answer would be 3 terms... C.

Which of the following is a perfect square trinomial?
yanalaym [24]
Your answer is D. 16x² - 56xy + 49y².

A perfect square trinomial is the result of a squared binomial, like (a + b)². Using this example, the perfect square trinomial would be a² + 2ab + b², as that is what you get when you expand the brackets.

Therefore, to determine which of these is a perfect square trinomial, we have to see if it can be factorised into the form (a + b)².

I did this by first square rooting the 16x² and 49y² to get 4x and 7y as our two terms in the brackets. We automatically know the answer isn't A or B as you cannot have a negative square number.

Now that we know the brackets are (4x + 7y)², we can expand to find out what the middle term is, so:

(4x + 7y)(4x + 7y)
= 16x² + (7y × 4x) + (7y × 4x) + 49y²
= 16x² + 28xy + 28xy + 49y²
= 16x² + 56xy + 49y².

So we know that the middle number is 56xy. Now we assumed that it was (4x + 7y)², but the same 16x² and 49y² can also be formed by (4x - 7y)², and expanding this bracket turns the +56xy into -56xy, forming option D, 16x² - 56xy + 49y².

I hope this helps!

What’s the answer 6x=4x+140
dmitriy555 [2]
1) given 6x = 4x + 140

2) subtract 4x from both sides => 6x - 4x = 4x - 4x + 140

=> 2x = 140

3) divide both members by 2 => 2x / 2 = 140 / 2

=> x = 70

4) Answer: x = 70

Need help like right now.
denpristay [2]

Let's go:


Big triangle:

12 + 3x - 6 = 3x + 6

10 + 8 = 18


\frac{10}{18} = \frac{3x - 6}{3x + 6} \\\\ 10.(3x + 6) = 18.(3x - 6) \\\ 30x + 60 = 54x - 108 \\\ 54x - 30x = 60 + 108 \\\ 24x = 168 \\\ x = 7


I hope I helped you.
