Answer:
16÷2
Step-by-step explanation:
It would be 16 divided by 2. This is because in the diagram they are splitting 16 by 2. Splitting 16 by 2 gets you two 8's.
Answer:
7
This question is tying to introduce an idea that
eventually becomes a calculus question ....
<u>(4^2 + 3(4)) - (0^2+3(0))</u>
4 - 0
<u>28 - 0 </u> = 7
4
Step-by-step explanation:
Answer:
8 + i
Step-by-step explanation:
What you need to simplify this is the following "definitions" of i to different powers.




Now we can sub these in for the various powers of i in our expression:

Simplifying a bit:

Since we know that the square root of i-squared is i, and that the square root of 49 is 7, we can get rid of the radial sign as follows:
6 - 6i + 2 + 7i
And the final answer, in a + bi form, is
8 + i
Its 0 cause 0 divided by any number is 0 but if it was 15/0, then it would be undefined
Answer: B
Begin by simplifying the given equation, so it's rearranged into standard form. Move all the terms onto one side, so they equal 0. This would result with
-3x-9=0. Quadratic formula is (-b±√(b²-4ac))/(2a). Standard form follow this variable format:
+bx+c. Use the numbers that correspond with each variable to substitute them into the quadratic formula. This would be
(-(-3)±√(-3²-4(4)(-9)/2(4).
