-2/7 because Y2 is -6 + 8 because a negative and a negative turns into a positive which equals 2 and X2 - X1 which is 7-14 which gives us -7 so -2/7

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:

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

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

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

The building is 24 (whatever’s you want ex. Meters, Feet) high. Because 38.7=tan^-1(height/30). Or cos(38.7)=30/hypotenuse. Hypotenuse=30/cos(38.7

Add the polynomials: (-5 - 7x^2); (5 + 7x^3) *

cestrela7 [59]

Answer:

$- 7 {x}^{2} + 7 {x}^{3}$

Step-by-step explanation:

$( - 5 - 7 {x}^{2} ) + (5 + 7 {x}^{3} ) \\ = - 5 - 7 {x}^{2} + 5 + 7 {x}^{3} \\ = - 7 {x}^{2} + 7 {x}^{3}$
