Answer: OPTION C

Step-by-step explanation:

For this problem it is important to remember that a trinomial is a polynomial with three terms and a binomial is a polynomial with two terms.

By definition, when you square a binomial, you get a perfect square trinomial:

(a \± b)^2=a^2 \± 2ab + b^2

Observe the trinomial given in Option C:

16 x^2 + 24 x y + 9 y^2

You can identify that:

 a^2=16x^2\\a=\sqrt{16x^2}=4x\\\\\\b^2=9y^2\\b=\sqrt{9y^2}=3y\\\\\\2ab=2(4x)(3y)=24xy

Therefore, you can conclude that  16 x^2 + 24 x y + 9 y^2 is a perfect square trinomial.

Answer:

6 1/2

Step-by-step explanation:

To double the recipe we would need to multiply all the ingredients by 2. But since it is asking about the peaches, we only need to multiply 3 1/4 by 2. First we make the 3 1/4 to an improper fraction. (multiply denom. by the 3 then add the numerator. then keep the same denominator). The improper fraction of 3 1/4 would be 13/4. Now we can multiply by 2. That would give us 26/4 which reduces to 13/2. To change this back to a mixed number, we divide 13 by 2. That would give us 6 with a remainer of 1. So our answer is 6 1/2. Sorry if it's confusing hope it helps :)
