(3,452 * 2) = round trip = 6,904.

6,904 * 3 = total distance = 20,712.

Therefore, the final answer is 20,712 miles.

Which expressions are equivalent to (2^2-9) (x + 3)?

mestny [16]

Answer:

$(x^2-3^2)(x+3)$

$(x-3)(x+3)(x+3)$

$(x-3)(x+3)^2$

Step-by-step explanation:

Given

$(x^2-9)(x+3)$

Required

Select 3 equivalent expressions

$(x^2-9)(x+3)$

Express 9 as 3^2

$(x^2-3^2)(x+3)$ --- This is one equivalent expression

Take $x^2 - 3^2$ as difference of two squares

$(x-3)(x+3)(x+3)$ -- This is another equivalent expression:

Solving further:

$(x-3)(x+3)(x+3)$ becomes

$(x-3)(x+3)^2$ -- This is another equivalent expression:

Hence, the equivalent expressions are:

$(x^2-3^2)(x+3)$

$(x-3)(x+3)(x+3)$

$(x-3)(x+3)^2$

Consider this right triangle with given measures.

OlgaM077 [116]

Answer:

$\sqrt{39}$

Step-by-step explanation:

I think the answer choices were supposed to be:

$\sqrt{3} , \sqrt{6} , \sqrt{39} , \sqrt{89}$

Pythagorean Theorem: a²+b²=c²

5²+b²=8²

25+b²=64

<em>Subtract 25 from both sides</em>

b²=39

<em>Square root both sides</em>

b= $\sqrt{39}$

Our answer is $\sqrt{39}$
