So to find a percent of increase you have to put the current number minus previous number(in this case 20-16) over the previous number(16 in this case) and multiply by 100.
So we have 20-16/16 multiplied by 100.
Since 4/16= 0.25,multiplying It by 100 gives you 25.
So the answer is 25%
Replace f(x) with f(3)
f(3) = -3x - 2
This means that you replace any x values with 3
f(3) = -3(3) - 2
Now solve. Multiply first then subtract
f(3) = -9 - 2
(f3) = -11
Answer:80.8%

£970=
£970*100%/£1200=80.8333333
80.8%
The value of x is 30
<u><em>Solution:</em></u>
Given that measure of exterior angle of regular polygon is 2x
The measure of interior angle is 4x
To find: value of x
The sum of an interior angle plus an exterior angle must be equal to 180 degrees (supplementary angles)
measure of exterior angle + measure of interior angle = 180
2x + 4x = 180
6x = 180
x = 30
<em><u>Finding the measure of an exterior angle</u></em>
measure of exterior angle = 2x = 2(30) = 60 degrees
<em><u>Finding the measure of interior angle</u></em>
measure of interior angle = 4x = 4(30) = 120 degrees
I'm guessing 0 but its probably wrong but i do know for 2-5 its going to be negative number that should help u the negative is -3 again i think its 0! But how should i know im in 8th grade!
