Answer:
4
Step-by-step explanation:
Let's call the width W and the length L.
We know the width is 3 less than the length, so:
W = L - 3
And we know the area is 28, so:
28 = WL
If we solve for L in the first equation:
L = W + 3
And substitute into the second equation:
28 = W (W + 3)
28 = W² + 3W
0 = W² + 3W - 28
0 = (W + 7) (W - 4)
W = -7, 4
Since W can't be negative, W = 4 units.
Answer:
A number that is greater than 0 is called a positive number
Step-by-step explanation:
Any number greater than zero is called a positive number.
On the number line, all the numbers greater than zero are to the right of zero.
In the on xy coordinate plane, a number greater than zero is located above the x-axis.
Hence the word which best completes the given statement is positive number
Centimeters, probably, which (for small things) isn't accurate.
