15y² - 11y

Step-by-step explanation:

We have to combine like terms in the given expression :

(7y² - 3y) + (8y² - 8y)

Here second degree term y² and y are the like terms.

So by combining these terms we can solve this.

(7y² + 8y²) - (3y + 8y)

= 15y² - 11y

Therefore, answer is 15y² - 11y

B. The coefficient for the x term must be twice the square root of the last term.

Step-by-step explanation:

The right answer is B.

A perfect square has the form $(a+b)^{2}$ , if we develop this expression would be

$(a+b)^{2} =a^{2} +2(a)(b)+b^{2}$

Notice when a trinomial is a perfect square, the second term is twic the square root of the third term, becase $\sqrt{b^{2} }=b$ , and twice means , now in our example, a=x .

Therefore, the right answer is B.
