Whenever you are given a cubic equation, or any equation, you always have to arrange it in a standard form first. For example, if you are given something like this, 3x2 + x – 3 = 2/x, you will re-arrange into the standard form and write it like, 3x3 + x2 – 3x – 2 = 0. Then you can solve this by any suitable method.
Answer:
56.25 grams
Step-by-step explanation:
36 divided by 8 is 4.5 and 4.5 multiplied by 12.5 gives you 56.25. Hope This Helps!
The answer is c because you plug in the values given. 4 times .75 is three. Three plus three is 6. For the other side you plug in .50. 6 times .50 is 3. 3-2 is 1. Then you are asked to find the perimeter, a rectangle has 4 sides so you do 6 on the top and bottom and 1 on each of the sides. When you add those all together you get 14 which is c.
