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

Happy snow day! My project

Answer:

21 Snowmen

Step-by-step explanation:

The perimeter of your yard is 25ft + 28ft + 25ft + 28ft = 106ft

Each snowman is 5ft across, so divide 106ft by 5ft.

106ft / 5ft = 21 with a remainder of 1ft
