Solving Square Roots Worksheet (x - k)^2 : Part 1
iVinArrow [24]

Answer:

1. x = +/- 2\sqrt{2} - 7

2. x = 3 +/- 2i\sqrt{3}

3. n = 2 +/- i\sqrt{2}

Step-by-step explanation:

1. Divide both sides by 2: (x + 7)^2 = 8

Square root both sides: x + 7 = +/- 2\sqrt{2}

Subtract 7 from both sides: x = +/- 2\sqrt{2} - 7

2. Square root both sides: x - 3 = \sqrt{-12}

Since there is a negative inside the radical, we need to have an imaginary number: i=\sqrt{-1} . So, \sqrt{-12} =i\sqrt{12} =2i\sqrt{3}

Add 3 to both sides: x = 3 +/- 2i\sqrt{3}

3. Divide by -5 from both sides: (n - 2)^2 = -2

Square root both sides: n - 2 = \sqrt{-2}

Again, we have to use i: n-2=\sqrt{-2} =i\sqrt{2}

Add 2 to both sides: n = 2 +/- i\sqrt{2}

Hope this helps!

sasho [114]

Answer:

first of all,

Step-by-step explanation:

In triangle ABC one side equal  and two sides equal  

Step-by-step explanation:

We are given a prism whose base is square with sides 8 in and height 12 in.

If we take cross section through vertices A, B and C

We will get a cross section as triangle.

In triangle ABC, sides are AB, BC and AC

AB is diagonal of top square whose side 8 in.

AC is face diagonal of front face.

BC is face diagonal of right face.

AC=BC≠AB

Hence, In triangle ABC one side equal  and two side equal  

Hope this helps!!
