Place the indicated product in the proper location on the grid. (4ya - 6xb)(4ya + 6xb)

k0ka [10]

Product of $(4ya - 6xb)(4ya + 6xb)$ is $16y^2a^2-36x^2b^2$

Step-by-step explanation:

We need to find the product of $(4ya - 6xb)(4ya + 6xb)$

Finding product:

Multiplying both terms:

$(4ya - 6xb)(4ya + 6xb)\\=4ya(4ya+6xb)-6xb(4ya+6xb)\\=16y^2a^2+24yaxb-24xbya-36x^2b^2\\=16y^2a^2-36x^2b^2$

So, product of $(4ya - 6xb)(4ya + 6xb)$ is $16y^2a^2-36x^2b^2$

What type of triangle is formed by joining the points D(7, 3), E(8, 1), and F(4, -1)?

attashe74 [19]

$D(7,3) \\
E(8,1) \\
F(4,-1)$

The lengths of the sides of the triangle:
$\overline{DE}=\sqrt{(8-7)^2+(1-3)^2}=\sqrt{1^2+(-2)^2}=\sqrt{1+4}=\sqrt{5} \\ \\
\overline{DF}=\sqrt{(4-7)^2+(-1-3)^2}=\sqrt{(-3)^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5 \\ \\
\overline{EF}=\sqrt{(4-8)^2+(-1-1)^2}=\sqrt{(-4)^2+(-2)^2}=\sqrt{16+4}=\sqrt{20}= \\
=\sqrt{4 \times 5}=2\sqrt{5}$

No sides are equal to each other, so it's a scalene triangle.

Check if the sides satisfy the Pythagorean theorem:
$(\sqrt{5})^2 + (2\sqrt{5})^2=5^2 \\
5+20=25 \\
25=25 \\
true$
They do, so it's a right triangle.

The triangle is a right scalene triangle.
