The answer to your question is 3
Answer:
Area = 16 in²
Step-by-step explanation:
Represent the length with L and the width with W
We have the following given parameters:
L = 4W
Perimeter = 20
Required
Determine the area.
The perimeter is calculated as thus:
Perimeter = 2(L + W)
Substitute 4W for L and 20 for Perimeter.
20 = 2(4W + W)
20 = 2 * 5W
20 = 10W
Solve for W
W = 20/10
W = 2
Recall that:
L = 4W
L = 4 * 2
L = 8
The area is then calculated as thus:
Area = L * W
Area = 8 * 2
Area = 16
Hence, the area is 16in²
Inside the root is 50-1
50-1 = 49
You would remain with root 49 but, if you calculate the square root the answer would be 7 because...
7•7 = 49
^ So, the answer is 7
Answer:
lma ooo how many times did you post
4x^2 - 16x + 8
Step-by-step explanation:
4(x-2)^2-8
4(x-2)(x-2)-8
4{x^2-4x+4}-8
4x^2 - 16x +16 - 8
4x^2 - 16x + 8
Answer:
D.
Step-by-step explanation:
To tell whether the domains can include 0, all you need to do is find where x = 0, and whether the y-value is real.
h(x) = sqrt(2x^2 + 5x - 3)
= sqrt(0^2 + 5 * 0 - 3)
= sqrt(-3)
Since this includes the square root of a negative number, h(0) is an imaginary number. That means that we can eliminate choices A and B.
If you look at the graph of w(x), when x = 0, there is a real value for the y-value on the graph. But, if you think about it, if you have 0 workers, there is no way that you can still be producing wrenches. So, the domain cannot contain 0.
Your answer will be D.
Hope this helps!!
