Answer:
Step-by-step explanation:
360 + 3*180 = -360 + 540 = 180
For four sides -360 + 180*4 = 360
n-2)*180
For a fifteen sided share the sum of angles = (15-2)*180 = 13*180
Answer:
x=h/4−3y−1/2
Step-by-step explanation:
h=4(x+3y)+2
1) <u>Distribute</u> the 4 to x and 3y:
h=4x+12y+2
2) Subtract a 12y and a 2 from both sides:
4x=h-12y-2
3) Divide everything by 4:
x=h/4-3y-2/4
4) Simplify -2/4 to -1/2:
x=h/4−3y−1/2
Step-by-step explanation:
what should be the result ?
all I can see are very simple expressions, but with no way to e.g. solve them to a single number or do something else specifically.
so, all I can do is resolve brackets and such.
6. -(x+4) = -x - 4
8. 7a(3b - 2c + 4) = 21ab - 14ac + 28a
10. 2/3 (1/4 x - 6) = 2/12 x - 6×2/3 = 1/6 x - 2×2 = 1/6 x - 4
