The correct answer of
![4{x}^{2} + 4x](https://tex.z-dn.net/?f=4%7Bx%7D%5E%7B2%7D%20%20%2B%204x)
if x=4 is 272.
to solve the equation if x equals 4, you must substitute the x of the 4.
![4( {4}^{3} ) + 4(4)](https://tex.z-dn.net/?f=4%28%20%7B4%7D%5E%7B3%7D%20%29%20%2B%204%284%29)
then solve by order of operations.
solve what is inside the parentheses first
![4(64) + 4(4)](https://tex.z-dn.net/?f=4%2864%29%20%2B%204%284%29)
then do the multiplication of the factors
![256 + 16](https://tex.z-dn.net/?f=256%20%2B%2016)
then the final step, adding, to get the solution of 272
Answer:
No, they can't.
Step-by-step explanation:
In geometry, cubic units can be defined as the units used to measure volume. The volume of a unit cube whose length, width and height are 1 unit each is 1 cubic unit. The length, width and height of the rectangular prism can be measured by counting the number of unit cubes.
(3-4i)(5+6i)
15+18i-20i-24i^2
15+18i-20i+24=
39-2i
