Answer:
a quantity representing the power to which a given number or expression is to be raised, usually expressed as a raised symbol beside the number or expression (e.g. 3 in 23 = 2 × 2 × 2).
Step-by-step explanation:
Length (L): 2w + 3
width (w): w
border (b): 
Area (A) = (L + b) * (w + b) <em>NOTE: This is assuming the width also has a border</em>
= (2w + 3 +
) * (w +
)
= 

= 

= 
That is =
(42.1/100)*37.5
=(421/1000)*(375/10)
=(157875/10000)
=15.7875
=15.8
=16
X^2 + x(x - 5) - x + 7
x^2 + x^2 - 5x - x + 7
2x^2 - 6x + 7

This is the equation we would use for this problem.
Now when we cross multiply, we get:
35(600)=100x
Simplify:
21000=100x
Divide each side by 100 to get x b itself:
210=x
So, as you can see, 210 is 35% of 600
