Answer:
16 cm
Step-by-step explanation:
Let the width be x
The length will be 3 x since the length is three times the width
Perimeter=2(l+w) where l is length and w is width
By substituting 128 cm for perimeter, x for w and 3 x for l then
128=2(3x+x)
128=8x
Therefore, the width is 16 cm, the width is 16*3=48 cm

Answer:
[-4, 3)
Step-by-step explanation:
We're talking about domain, which would be the least and greatest possible value x could be. In this graph, x is, at the least, -4. So we would use the bracket and write -4. The highest value x could be is 3, but if you look closely, the point is has an open circle, meaning we would use a parentheses for this side.
So, the answer is [-4, 3).
Hope this helps!!!
Answer:
So, to work with negative exponents you need to multiply like a positive exponent, and move the decimal over double the digits place each time.
Examples:
If it is 4 with an exponent of -2, then you will multiply 4 by 4 to get 16, and then move the decimal over double the amount of digits. There are two digits, so you will move the decimal over four digits.
So the answer to 4 with an exponent of -2 would be .0016.
I believe it’s 120? Not for sure tho so don’t quote me
