X^2+ 6x - 9 = 0

Use the quadratic formula
x = (<span><span>−b± sqrt (<span>b^2−4ac</span></span>)) / 2a
</span>
a = 1
b = 6
c = -9

x = −6± sqrt (6^2−4(1)(-9) / 2(1)
x = (−6± sqrt(72))/2

so these are your two solutions to the equation
x = 1.243
x = -7.243

Question: A square with sides of length 5 is positioned inside a square with sides of length 7. What is the total area between t

Sergio [31]

Answer:

The total area between the squares is of 24 units squared.

Step-by-step explanation:

Area of a square:

The area of a square of side length l is given by:

$A = l^2$

Area between figures:

The area between two figures is the area of the larger figure subtracted by the area of the smaller figure.

Larger square:

Square with side of length 7. So

$A_l = 7^2 = 49$

Smaller square:

Square with side of length 5. So

$A_s = 5^2 = 25$

What is the total area between the squares? 

$T = A_l - A_s = 49 - 25 = 24$

The total area between the squares is of 24 units squared.

(x – 4)(x+6)<br> Need help simplify

Ksivusya [100]

The answer would be 2x^2+2x-24

using foil, you would multiply together x & x, x & 6, -4 & x, and -4 & 6, then add them together.
