Answer:

The side of original square was 7.24 inches

Step-by-step explanation:

(x+3)(x+3) =2(x)(x)

x² + 6x + 9 = 2x²

reduce:

x² - 6x - 9 = 0

(x + 1.24)(x - 7.24) = 0

x = 7.24

<h3>The changes to a polygon</h3>

1. If the number of sides of the polygon should increase then the measure of the interior angle would increase by 180.

2. A regular polygon has the sum of its external angles as 360. This is solved as 360/n = 0

Hence the value of the exterior would move towards 0 as its sides increases.

4. As the total sum of the of the polygon changes, it would tend towards infinity.

5. The total sum of the exterior angles as the number of sides changes would tends towards 360 degrees.

If x= 2 what does y equal
Ivahew [28]

Answer:6

Step-by-step explanation:

4.8(x)+1.2(y)=2.4

y would equal -6.

4.8(2)+1.2(y)=2.4

9.6 + 1.2y = 2.4      subtract 9.6 from both sides

1.2y = - 7.2    divide by 1.2 on both sides

y = -6
