Answer:
a. n x (2n +1) = 10
b. length: 5 width: 2
Step-by-step explanation:
5 is 1 more then 2 times 2
<span>The answer: b. translated according to the rule (x, y) → (x + 8, y + 2) and reflected across the x-axis
If you make the drawing of the situation you realize the you need a reflection through the x-axis, but first you need to translate the polygon several units to the left and upward.
You can see that all the x-coordinates have increased 8 units, so the solution has to include x + 8.
Also, you see that you have to move the polygon 2 units upward before doing the reflection so the solution has to include y + 2.
So, the answer is (x,y) ---> (x + 8, y + 2) and then reflection across the x-axis.

Answer:
11
Step-by-step explanation:
for this question we can look at the whole answer for the square root of 120 which equals 10.9544511501
![\sqrt{120} = 10.9544511501](https://tex.z-dn.net/?f=%5Csqrt%7B120%7D%20%3D%2010.9544511501)
now looking at our answer (10.9544511501) we want to find the nearest WHOLE NUMBER. in the current answer the whole number is 10, followed by many decimals.
10.9544511501
but to find the nearest whole number we have to round the place value BEFORE our whole number. (in this case the 9)
10.9544511501
we can now look at this highlighted section of our equation and think... is 10.9 closer to 11 or 10. well logically, to get to 11 from 10.9 we only have to go up by 0.1, rather than to get to 10, where you have to subtract 0.9.
10.9 + 0.1 = 11
10.9 - 0.9 = 10
But to make it easier, remember the rule:
the place value one place to the RIGHT of what you're rounding to, is what determines the new number. (in this case the .9)
and as any number 5 or above rounds up, we can say that our new number, rounded to the nearest whole number equals 11
10.9 rounded to the nearest whole number = 11
