Which method can't you use to solve this problem? x^2-47=0

☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆A.) Factoring

B.) Squareroots

C.) Quadratic Formula

I️ dislike this question because all 3 methods could be used to solve. Although there are no rational factors, this equation can obviously be rewritten as a difference of squares as (x + sqrt(47))(x-sqrt(47)). A square root could be used by adding 47 to both sides and taking the square root. The quadratic formula can clearly be used as well. The result for each of these methods is that x = +-sqrt(47), which is the correct answer.

3x + 8 = -x + 20 What is x?
g100num [7]
First, lets take all the x values on one side.

3x + x + 8 = -x + x + 20
4x + 8 = 20

Now, lets put the numbers on the other side.

4x + 8 - 8 = 20 - 8
4x = 12
x = 3

Hope this helps!

If a triangle has side lengths 5, 5, and 8, then the triangle should be classified as isosceles.

This is because an isosceles triangle has two sides of the same length and one side of a different length. This isn’t an equilateral triangle (where all sides are of equal length) or a scalene triangle (where all sides are of different lengths).

Hope this helps!
