Step-by-step explanation:
mutiply (-5+i) and 2i with 2i
2i × 2i = 4i^2 ➡-4
2i × (-5+i) = -10i + 2i^2 ➡-10i -2
then do the division
(-10i -2)/-4 = (5i + 1)/2
Multiply the numerator and denominator by the conjugate of 2i to make the denominator a real number:
-5 + 1 / 2i
= -5 + i /2i x i/i
= -5i + i^2 / 2 x i^2
Rewrite i^2 as -1:
-5i + -1 / 2 x -1
Simplify:
= -1 - 5i / -2
Split the fraction into two separate ones:
1/2 + 5i/2

Answers
Answer: substances that are made up of only one type of atom
Step-by-step explanation:
Element is a pure substance which is composed of atoms of similar elements. Example: Carbon (C)
Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water
The subatomic particles with a positive charge are called as protons and are located in the nucleus of the atom.
Thus elements aresubstances that are made up of only one type of atom.

Final answer:
The equation that is equivalent to 6 3/3 x 3 1/4 = 19 is option B: 19 ÷ 3 1/4 = 6 3/4.
Explanation:
To find the equation that is equivalent to 6 3/3 x 3 1/4 = 19, we need to perform the operations on both sides of the equation. Let's start by simplifying the multiplication on the left side:
6 3/3 x 3 1/4 = 19
19/1 = 19
Now, let's examine each option:
A. 3 1/4 ÷ 19 = 6 3/4: This equation does not give us an answer of 19, so it is not equivalent.
B. 19 ÷ 3 1/4 = 6 3/4: This equation does give us an answer of 19, so it is equivalent.
C. 3 1/4 ÷ 6 3/4 = 19: This equation does not give us an answer of 19, so it is not equivalent.
D. 6 3/4 ÷ 3 1/4 = 19: This equation does give us an answer of 19, so it is equivalent.
Therefore, the equation that is equivalent to 6 3/3 x 3 1/4 = 19 is option B: 19 ÷ 3 1/4 = 6 3/4.

If you're trying to factor a quadratic in Algebra I:
There are no two integers that can solve this problem!
Your quadratic is prime!
If you're trying to solve a quadratic (find x):
The factoring approach will not work for the same reasons listed above.
Try using splitting the middle or the quadratic formula instead.
Here's how you would solve it from a more advanced approach.
If you don't know what this stuff is, just ignore it.
ab = -18, a + b = -9
Find a in terms of b.
a = -9-b
Substitute this for a in the first equation.
(-9-b)b = -18
-9b-b² = -18
Multiply everything by -1 to get rid of all these negative signs.
b² + 9b = 18
Bring over that 18.
b² + 9b - 18 = 0
Apply the quadratic formula.
(a = 1, b = 9, c = -18)
If you need to write two distinct numbers, just write out one with a + and one with a - in place of the plus-minus sign.
