Answer:

Step-by-step explanation:

square = 468 m² x² + (6+x)² = 468 [Area of a square = side²] x² + (6)² + x² + 2×6×x= 468 [(a+b)²= a²+b²+2ab] 2x² + 36 + 12x= 468 2x² + 12x + 36 - 468= 0 2x² + 12x + 36 - 432 = 0 2(x² +6x - 216)= 0 x² +6x - 216 = 0 x² +18x -12x -216 =0

So say we have the number: 54,321

The 5 would be worth 50,000 meaning it's in the ten thousands place.

The 4 would be worth 4,000 meaning it's in the thousands place.

The difference between them is a zero, so the ten thousands place is 10 times bigger than the thousands place

Hope that helps :)

Fatoring Trinomials<br> x^2+2x=-1

Musya8 [376]

Answer:

$\Huge \boxed{x=-1}$

Step-by-step explanation:

$x^2+2x=-1$

Adding 1 to both sides of the equation.

$x^2+2x+1=-1+1$

$x^2 +2x+1=0$

Factoring the left side of the equation.

$x^2 +1x+1x+1=0$

$x(x+1)+1(x+1)=0$

$(x+1)(x+1) = 0$

$(x+1)^2 =0$

Taking the square root of both sides of the equation.

$\sqrt{(x+1)^2} =\sqrt{0}$

$x+1=0$

Subtracting 1 from both sides of the equation.

$x+1-1=0-1$

$x=-1$

To find the range of data, you first order the data least to greatest:
7, 12, 15
Then you subtract the smallest number from the largest:
15-7=8

The range is 8.
