Hey there! I'm happy to help!
How many times does 20 go into 48?
48/20=2.4
So, we multiply our amount of flour for 20 cookies by 2.4.
2.25×2.4=5.4
Therefore you would need 5.4 or 5 2/5 cups of flour to make 48 cookies.
Have a wonderful day! :D

To find the area of a parallelogram, multiply the base by the height. the formula is: A= Base times height where B is the base, and H is the height, and * means multiply. the base and height of a parallelogram must be perpendicular
Answer:
2 - 8i
Step-by-step explanation:
The additive inverse of something is basically the opposite of it. Another way to say this is that when you add the additive inverse to -2 + 8i, it will equal 0.
<u>An example:</u>
The additive inverse of 7 is -7 because not only is it the opposite, but also when you add 7 and -7, it equals 0.
<u>To solve</u>
So all you need to do is find the opposite of -2 + 8i. You can write it as:
-(-2 + 8i) With the negative in the front because we want to find the opposite.
This then equals:
2 - 8i
You can check your answer by adding -2 + 8i and 2 - 8i to see if it equals 0:
(-2 + 8i) + (2 - 8i) → and it does equal 0
<u>ANSWER:</u> 2 - 8i
Hope you understand and that this helps with your question! :)
