Answer:
(x² - 9)(x² - 2) = 0
x = 3 or √2
Step-by-step explanation:
To factor a polynomial, you need to find two expression that when multiplied together using FOIL (first, outside, inside, last) will produce the polynomial. In this case the polynomial 
can be factored into:
(x² - 9)(x² - 2) = 0
Setting each of these expressions equal to '0':
x² - 9 = 0 or x² = 9 so √x² = √9 or x = 3
x² - 2 = 0 or x² = 2 so √x² = √2 or x = √2
Answer:
Christy is correct
Step-by-step explanation:
you dont say the numbers in words all the time, so it makes a lot more sense.
You are basically trying to find the area of two triangles and a rectangle.
Rectangle= A= length*width
Triangle= A= 1/2*base*height
Rectangle:
1.5*1.9= 2.85
Two triangles:
A= 1/2* 0.5*1.5
A=1/2*.75
A=0.375
Multiply that by two, because the triangles are the same.
.75
.75+2.85= 3.6
3.60 ft^2 <== the answer :)
