Answer: x=-3

Step-by-step explanation:

First let's eliminate the square root

(\sqrt{x^2-5x+2})^2=(\sqrt{x^2+17})^2\\x^2-5x+2=x^2+17

Now subtract x^2\\ from both sides

x^2-5x+2-x^2=x^2+17-x^2\\-5x+2=17

Subtract 2 from both sides

-5x+2-2=17-2\\-5x=15

Finally divide both sides by -5

\frac{-5x}{-5} =\frac{15}{-5} \\x=-3

Answer:

5<em>i</em>

Step-by-step explanation:

  1. = \sqrt{-1 * 25}
  2. = \sqrt{-1}\sqrt{25}
  3. = \sqrt{-1} * 5

in ABC the measure of angle A is 2x+3 the measure of angle B is 4x+2 the measure of angle C is 2x-1 what are the measures of the
Virty [35]


IN A triangle, sum of all angles = 180 degrees

2x + 3 + 4x+2 + 2x -1 = 180

8x +4  = 180

8x = 176

x = 176 /8 = 22 degrees

the angles are A = 2(22)+3 = 44+3 = 47 DEGREES

B = 4(22)+2 = 88 + 2 = 90 DEGREES

C = 2(22) -1 44-1 = 43 DEGREES
