Answer:
Add the numbers together and divide by the number of numbers. (The sum of values divided by the number of values). Arrange the numbers in order, find the middle number. (The middle value when the values are ranked).
Point A is (-4,1) .Point A is reflected along y axis so y will remain same and x coordinate will have opposite sign .The reflected point A' ---(4,1) .The point is now reflected along x axis so its x ordinate will remain same and y will be at an equal distance from x axis The new reflected point is A" (4,-1) .The point is now rotated 180 degrees the x and y coordinate changes sign so the rotated final point is A"'( -4,1).
Answer:
x ≈ 17.5
Step-by-step explanation:
using Pythagoras' identity in the right triangle.
the square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is
x² = 9² + 15² = 81 + 225 = 306 ( take square root of both sides )
x = 
≈ 17.5 ( to the nearest tenth )
Try calculating each of these yourself:
<span>First, 34(58 + 9) = 34(67) = 2278 </span>
<span>A. 34 x 67 = 2278 </span>
<span>B. 58(34 + 9) = 58(43) = 2494 </span>
<span>C. 34 x 58 + 34 x 9 = 34 x (58 + 9) = 34 * 67 = 2278 </span>
<span>D. 1,972 </span>
<span>So the answer is B and D are not equal to 34(58 + 9).

Answer:
3420°
Step-by-step explanation:
The sum of angle measures of an n-gon is ...
angle total = (n-2)×180°
For n = 21, the angle total is ...
21-gon total = (21 -2)×180° = 3420°
