Which products result in a perfect square trinomial? Select three options.

Kazeer [188]

Answer:

Second option: $(xy+x)(xy+x)$

Third option: $(2x-3)(-3+2x)$

Fifth option: $(4y^2+25)(25+4y^2)$

Step-by-step explanation:

By definition, a perfect square trinomial can be obtained by squaring binomials.

Then:

$(a+b)^2=(a+b)(a+b)=a^2+2ab+b^2\\\\(a-b)^2=(a-b)(a-b)=a^2-2ab+b^2$

Knowing this, to obtain a perfect square trinomial, the binomials that you multiply must be equals.

Therefore, the products result in a perfect square trinomial are:

$(xy+x)(xy+x)=(xy+x)^2=(xy)^2+2(xy)(x)+x^2=x^2y^2+2x^2y+x^2$

$(2x-3)(-3+2x)=(2x-3)^2=(2x)^2-2(2x)(3)+3^2=4x^2-12x+9$

$(4y^2+25)(25+4y^2)=(4y^2+25)^2=(4y^2)^2+2(4y^2)(25)+25^2=16y^4+200y^2+625$

kirill [66]

Answer:

Step-by-step explanation:

We have been given that your parents have been advised to save 5% of their income for your college education, which would include money for housing, tuition, books, and fees. They had an average household income of $48,948.

Let us find 5% of average household income to find the savings of your parents in one year.

$\text{Savings of your parents in one year}=\$48,948\times \frac{5}{100}$

$\text{Savings of your parents in one year}=\$48,948\times0.05$

$\text{Savings of your parents in one year}=\$2447.40$

Therefore, your parents would have saved $2447.40 is one year.
