Before being simplified completely, the product of a binomial and a trinomial has what terms

As a binomial has two terms and a trinomial has 3 terms.

If all the terms of binomial is different and all the terms of trinomial is also different, and there is no common term between binomial and trinomial then total number of terms in the product of binomial and trinomial will be 6.

→Number terms in the product of binomial and trinomial= number of terms in binomial × Number of terms in trinomial = 2×3 =6

for example, A=p+q and B=a+b+c

A×B= (p+q)(a+b+c)=pa +p b+p c+q a+q b+q c= 6 terms , if there is no like term.

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
