Answer:
-12x
Step-by-step explanation:
(-9x+1) - (3x+1)
-9x + 1 - 3x - 1
-12x
Answer:
1. 360
2. Yes because in a regular hexagon all angles are congruent so the exterior angles are as well
3. (i) 60 (ii) 120
4.
(i) 1. 360 2. Yes because in a regular octagon all angles are congruent so the exterior angles are as well 3. (i) 45 (ii) 135
(ii) 1. 360 2. Yes because in a regular 20-gon all angles are congruent so the exterior angles are as well 3. (i) 18 (ii) 162
Step-by-step explanation:
Works for each polygon
1. First take the number of sides and subtract it by 2 then multibly that by 180
6-2=4x180=720
Then divide by the number of angles and subrtact that number by 180 to find the measure of one exterior angle
720/6=120
180-120=60
Then multiply by the number of exterior angles
60x6=360
2. Regular polygons always have equal angles so the exterior angles are as well
3. Put in your numbers from earlier
(i) 60 (ii)120
Hope this helps! :)

Answer:
9/40
Step-by-step explanation:
To find the price per can, we take the cost and divide by the number of cans
$5.40/24
5.4/24
Since there is a decimal in the numerator, multiply the top and bottom by 10
5.4/24 * 10/10
54/240
Divide the top and bottom by 6
9/40
