gulaghasi [49]

Answer:

1. A number having 2, 3, 7 or 8 at unit's place is never a perfect square. In other words, no square number ends in 2, 3, 7 or 8. The number of zeros at the end of a perfect square is always even. In other words, a number ending in an odd number of zeros is never a perfect square.

2. Only those numbers, when squared will have 6 at their unit place are 4 and 6 Because 4×4 = 16 and 6×6 = 36(i dont know if this is what you were looking for)

Which of the following is the simplified expression of 2 square root of -16 + the square root of 225 in standard form, a plus b
LuckyWell [14K]

Answer:

<em>The standard form like (a+bi) will be:  15+8i</em>

Step-by-step explanation:

Given expression is:   2\sqrt{-16}+\sqrt{225}

First factoring out -16 as (-1×16) , we will get....

2\sqrt{-1}*\sqrt{16}+\sqrt{225}

Now, replacing \sqrt{-1} as  i .......

2i\sqrt{16}+\sqrt{225}

Finally, simplifying the radicals in the above expression, we will get......

2i*4+15\\ \\ =15+8i

Thus, the standard form like (a+bi) will be:  15+8i

A rectangular prism has a length of 12 feet, a width of 6 feet, and a height of 2 feet.
aliina [53]
The volume of the prism is 144 ft^3. If we use the letter V to represent volume, the formula for the volume of a rectangular prism is V=length*width*height. When you plug in the numbers, the equation is V=12*6*2. When you multiply these three numbers together, you get 144. Because you are finding the volume, your units are cubed, so your answer is 144 ft^3. I have attached an image of this problem written out (I’m sorry if the image is bad, I drew it on my phone). If you need any more help or any clarification, please let me know and I will be happy to help!
