Answer:
x=15 degree
Step-by-step explanation:
5x +5+6x -1+3x+5x+3+4x+8 =360 degree (exterior angles of pentagon is 360 degree)
23x +15 =360
23x=360-15
x=345
x=345/23
x=15 degree
<span>3(a+(6x)y) was clearly multiplied out as seen by the 3a and 18xy, so the distributive property was used there. In addition, the commutative and associative properties state that you can rearrange sums, so those were used too </span><span />
The question we need to ask is what percent of 2 is 40?
40 is 20 times 2 so 20 would be 2,000%
We need to subract 100% from any percent change:
2,000% - 100% = 1,900%
ANSWER: 1,900%
