What are the solutions to the equation x² = 169? Choose all answers that are correct. A. 13 B. –13 C. 84.5 D. –84.5

Answers

Answer 1

Answer: $x^(2) = 169$

First, we need to take the square root of each side.
$x = \pm \sqrt169$

Second, we now have to find the square root of 169 to solve this. Since 13 × 13 = 169, the square root of 169 is 13. The plus-minus symbol means in this case, the solution can be -13 and positive 13. To answer your question, option A) 13, and B) -13 are the solutions to the equation.
$x = \pm 13$

Answer: $\pm13$

3,200 oz = __________lb

Answers

There are 16 ounces in 1 pound, so all we need to do to find out how many pounds are in a certain amount of ounces is divide the amount of ounces by 16.

3200 / 16 = 200

3,200 oz = 200 lbs
Hope that helped =)

So,

First, the conversion between ounces and pounds is:
16 oz. = 1 lb.

So:
3200 (16 * 200) oz. = 200 lbs.
