Answer:

D. z = 2

Step-by-step explanation:

4z - 4.4 = 3.6  also means 4z = 3.6 + 4.4  which is 4z = 8

4 times 2 = 8

For proof do 4 times 2 minus 4.4 = 3.6

What is the sum of StartRoot negative 2 EndRoot and StartRoot negative 18 EndRoot? 4 StartRoot 2 EndRoot 4 StartRoot 2 EndRoot i
Sveta_85 [38]

Adding  \sqrt{-2}\,\,and\,\,\sqrt{-18} we get 4\sqrt{2i}

Option C 4 StartRoot 2 EndRoot i is correct.

Step-by-step explanation:

We need to find the sum of: \sqrt{-2}\,\,and\,\,\sqrt{-18}

Finding sum:

\sqrt{-2}+\sqrt{-18}

\sqrt{-2} can be written as \sqrt{2}i

\sqrt{-18} can be written as \sqrt{18}i

We know 18 = 2x3x3 = 2x3^2 so,

\sqrt{2i}+\sqrt{2\times 3^2}i

\sqrt{2i}+3\sqrt{2}i

Adding like terms:

4\sqrt{2i}

So, adding  \sqrt{-2}\,\,and\,\,\sqrt{-18} we get 4\sqrt{2i}

Option C 4 StartRoot 2 EndRoot i is correct.
