Answer:

d = 5

Step-by-step explanation:

d = √ (X2 - X1)^2 + (Y2 - Y1)^2

d= √ (-3 - -7)^2 + (1 - -2)^2

d= √ (4)^2 + (3)^2

d = √16 + 9

d = √25

d = 5

Answer: Choice B

$\left\{ \ 3, 5, \sqrt{34} \ \right\}$

=========================================================

Explanation:

We'll be using the converse of the pythagorean theorem.

If we had a triangle with sides a,b,c and $a^2+b^2 = c^2$ was true, then we have a right triangle. Note: c is always the longest side

For the first answer choice we have: a = 5, b = 8, c = 12

Then,

$a^2+b^2 = c^2\\\\5^2+8^2 = 12^2\\\\25+64 = 144\\\\89 = 144\\\\$

which is false. This shows that we do not have a right triangle with sides 5,8,12. This rules out choice A. Choice C is a similar story.

Choice B on the other hand works because

$a^2+b^2 = c^2\\\\3^2+5^2 = (\sqrt{34})^2\\\\9+25 = 34\\\\34 = 34\\\\$

We have a true statement at the end, which confirms <u>choice B</u> is a right triangle.

Adding/subtracting polynomials <br>

Nuetrik [128]

Answer:

$g(x) - h(x) = { - x}^{4} - 11x$

Step-by-step explanation:

$g(x) = {6x}^{2} - 4x + {3x}^{4}$

$h(x) = {6x}^{2} + 4 {x}^{4} + 7x$

$g(x) - h(x)$

$({6x}^{2} - 4x + {3x}^{4}) - ( {6x}^{2} + 4 {x}^{4} + 7x)$

${6x}^{2} - 4x + {3x}^{4} - {6x}^{2} - 4 {x}^{4} - 7x$

$( {3x}^{4} - {4x}^{4}) + ( {6x}^{2} - 6x {}^{2} ) + ( - 4x - 7x)$

${ - x}^{4} - 11x$
