HURRY PLEASE!!!!!!!!!!!!!!!!!!!

Answer: $FH=8\sqrt{51}$

Step-by-step explanation:

This is a special right triangle that has 30, 60 and 90 degress corners. Because it is a special triangle, it also has side length values which always consistent relationship with one another.

Side opposite the 30° angle: x

Side opposite the 90° angle: 2x

So, $FG=8\sqrt{17}$

Then use Pythagorean theorem. $c^{2} =a^{2} +b^{2}$

$(16\sqrt{17} )^{2} =FH^{2} +(8\sqrt{17} )^{2}$

$FH^{2} =4352-1088$

$FH=\sqrt{3264}$

$FH=8\sqrt{51}$

Which number rounds to 260 when rounded to the nearest 10?

mylen [45]

I looked it up and got this........

What is 260 rounded to the nearest ten?
Here we will tell you what 260 is rounded to the nearest ten and also show you what rules we used to get to the answer. First, 260 rounded to the nearest ten is:
260
Remember, we did not necessarily round up or down, but to the ten that is nearest to 260.
When rounding to the nearest ten, like we did with 260 above, we use the following rules:
A) We round the number up to the nearest ten if the last digit in the number is 5, 6, 7, 8, or 9.
B) We round the number down to the nearest ten if the last digit in the number is 1, 2, 3, or 4.
C) If the last digit is 0, then we do not have to do any rounding, because it is already to the ten.

Which of the following is an example of the difference of two squares

True [87]

Complete Question: Which of the following is an example of the difference of two squares?

A x² − 9

B x³ − 9

C (x + 9)²

D (x − 9)²

Answer:

A. $x^2 - 9$ .

Step-by-step explanation:

An easy way to spot an expression that is a difference of two squares is to note that the first term and the second term in the expression are both perfect squares. Both terms usually have the negative sign between them.

Thus, difference of two squares takes the following form: $a^2 - b^2 = (a + b)(a - b)$ .
