The total sum is 180 because 3 angles = 180
54 + 11s + 7s = 180
-54. -54
18s = 126
S = 7
The rule can be “four to the bottom, and four the left”
Percent change=100 times change/original
change=original-new
change=90-84.50=5.5
percent change=100 times 5.5/90
percent change=550/90
percent change=6.11111
percent change=6.1%
(fg)(x) = (3x + 6) (<span>2x^2)
</span>(fg)(x) = 6x^3 + 12x^2
hope it helps
