Answer:
1440
Step-by-step explanation:
3(x+4)(x+1)(x+2)(x-2)
Let x= 4
3(4+4)(4+1)(4+2)(4-2)
Evaluate each parentheses
3 ( 8) (5)( 6) (2)
Multiply
1440
If you meant
3(x+4)(x+1)
= 3(4+4)(4+1) = 3 * 8 *5 = 120
(x+2)(x-2)=(4+2)(4-2) = 6 *2= 12
Yes it is ..... it is good
On the sheet, it's not even asking you for the dimensions.
It's just asking you to set up the <em>equation that you would use</em>
to find the dimensions. That's a great way to do it, because
nobody actually needs the answers, the whole thing is only
meant to help you learn HOW to find them.
==========================================
Call the width of the window 'W' .
We know that the length is 5 feet more than the width, so the length is (W + 5).
The area is (length times width).
Area = (W + 5) times (W).
36 = (W + 5) W
36 = W² + 5W
Subtract 36 from each side:
W² + 5W - 36 = 0
That's choice-4 .

Step-by-step explanation:
There isn’t a accurate slope to find if they are parallel or perpendicular
Answer:
x^2 - 6x + 8 x - 2
x
0 8 -2
1 3 -1
2 0 0
3 -1 1
4 0 2
5 3 3
The solutions are in red ⇒ x = 2 and x = 5
