First step: x= ± √ 121
Second step and correct answer: x= ± 11
Because: x^2 = x= ± √
Answer:
I believe the answer is the second one
Step-by-step explanation:
Answer: The equation can be written as 8n = 99.2.
Step-by-step explanation:
In my answer, I used the variable n to distinguish itself as one side of the stop sign. 99.2 is the final perimeter in inches.
A stop sign is an octagonal shape (otherwise, it is made up of 8 equal sides). Therefore, with this information, you can interpret that the length of one side would be equal to the length of all of the other sides.
Hence, the answer can be represented as 8n = 99.2.
Answer:
I think it is 8.9 and 9.1
Step-by-step explanation:
because
3.1 its way off so no
4.2 and 4.3 it ehh
but 4.5 and 4.6 it close
hope this helps

Answer:
90°
Step-by-step explanation:
Any corner angle in a rectangle is 90°. Rotating the figure does not change that. Angle O' = 90°.
_____
<em>Additional comment</em>
No rigid transformation (translation, rotation, reflection) changes any angles. Nor does uniform dilation (the kind we usually study). Hence any rectangle that is translated, rotated, reflected, or dilated will still have all angles measuring 90°.
