Answer:
Step-by-step explanation:
x² - x -6 = x² + 2x - 3x - 3*2
=x(x + 2) - 3(x + 2)
= (x + 2 )(x - 3)


Answer:
I got x = 1
Step-by-step explanation:
First to isolate the variable you add 3 to both sides which will give you 1/2x is less than or equal to 2. Then divide both sides by 1/2 and you will get x = 1. To check the answer I just did:

And since -2.5 is less than -1 this statement is true. x does in fact equal 1
First get the length of the side the was cut (Hypotenuse).
We can use Pythagorean theorem: a^2+b^2 = c^2
a = 8, b = 3 = 1.5, c = ?
plug into forumla
8^2 + 3^2 = 73
a=8,
b=1.5,
c = sqrt( 73) or 8.5
Now add all sides together to get perimeter...
8+3+8.5 = 19.5
The perimeter of each sheet is 19.5in.
Answer:
-5 and 20
Step-by-step explanation:
-5 + 20 = 15
-5 * 20 = -100
