Quan bought 8.6 meters of frabic. how many cm of fabric did he buy
stira [4]
When you convert from meters to centimeters, you always multiply by 100, which means that 1 meter = 1 * 100 cm = 100 cm
So, 8.6 meters = 8.6 * 100 cm = 860 cm 

Hope this Helps :)

After 22 weeks of training, Amanda learned a total of 55 appetizer recipes. After 6 weeks of training, she will learn
Artist 52 [7]

Answer: 15

Step-by-step explanation:

My answer is correct because, if in 22 weeks she learned 55 recipes of appetizers, the we have to divide 55 by 22. And 55 divided by 22  equals 2.5. So now since we have that and they are asking us what would it be for a total of 6 weeks then we just have to multiply 2.5 and 6. And 2.5 times 6 equals 15.

If –3 i is a root of the polynomial function f(x), which of the following must also be a root of f(x)? –3 – i –3i 3 – i 3i
Ber [7]

If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

<h3>How to determine the true statement?</h3>

The root of the polynomial function is given as:

-3 + i

The above root is a complex root.

If a polynomial has a complex root, then the conjugate of the root is also a root of the function

The conjugate of -3 + i is -3 - i

Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
