Question

Solve 5x^2 = 180 algebraically.

Answer 1

Answer:

x=6

Step-by-step explanation:

$5x^2 =180\\x^2 =\frac{180}{5}\\x^2 =36\\\\x=\sqrt{36} \\\\x =6$

Answer 2

Answer:

x = 2.683281573

Step-by-step explanation:

Solve the problem backwards:

5x^2 = 180

sqrt of 180 = 13.41640786 = 5x

13.41640786/5 = 2.683281573

x = 2.683281573

We can test it:

(5(2.683281573))^2 = 180
