Answer:
If each side of pentagon is doubled then its perimeter will also be doubles. The new perimeter is 30 feet.
Step-by-step explanation:
Let the length of all five sides of pentagon = <em>v, w, x, y</em>, and <em>z</em>.
Perimeter of pentagon = Sum of lengths of its all five sides = (<em>v + w + x + y + z</em>) = 15 feet
If each side of pentagon is doubles then,
New perimeter of pentagon = (2<em>v + </em>2<em>w + </em>2<em>x + </em>2<em>y + </em>2<em>z</em>)
= 2 (<em>v + w + x + y + z</em>)
= 2 (15)
= 30 feet
Therefore, if each side of pentagon is doubled then its perimeter will also be doubled.
Total = 4000 * (1 + .07 / 4)^4*10
Total = 4000 *

The answer is x = 6.
Here are the steps.
1. Simplify 2/6 to 1/3 ( 2/x = 1/3 ).
2. Multiply both sides by x ( 2 = 1/3x ).
3. Simplify 1/3x to x/3 ( 2 = x/3 ).
4. Multiply both sides by 3 ( 2 * 3 = x ).
5. Simplify 2 * 3 to 6 ( 6 = x ).
Now finally switch it up and the answer is x = 6.
