<span>The area of any regular polygon with n sides of length s is
s = 100/100 = 1
Area =~ 795.55 sq units</span>
Andy's age = x
Jeff's age = x-2
Andy's age in five years = x+5
Jeff's age in five years = x-2+5
The sum of their ages in five years = x+5 + x-2+5
x + 5 + x - 2 + 5 = 40
2x + 8 = 40
<u> -8 -8</u>
2x = 32
<u> :2 :2</u>
x = 16
x - 2 = 14
<u>Andy is 16 years old and Jeff is 14 years old</u>
Y = mx + b
-3 = 1/2(-2) + b
-3 = -1 + b
b = -2
equation
y = 1/2x - 2
standard form
1/2x - y = 2
or
x - 2y = 4
-6x + 4
Looking at the first term we know it's the power times the base to the power of to the original minus one.
(-3x×2)^(2-1) = -6x
Then the second term would just be the leading coefficient 4.
By the intersecting chords theorem, you have
