Hello there! The value of x is 20 or -20

"20 or - 20" is one answer so you are supposed to answer 20 or -20, not choose only one.

Step-by-step explanation:

$\large{ \frac{ {x}^{2} }{ {5}^{2} } = {4}^{2} }$

First, we simplify 5² and 4²

$\large{ \frac{ {x}^{2} }{25} = 16}$

Multiply the whole equation by 25 to get rid of the denominator.

$\large{ \frac{ {x}^{2} }{25} (25) = 16(25)} \\ \large{ {x}^{2} = 400}$

Square both sides and solve the equation.

$\large{ \sqrt{ {x}^{2} } = \pm{ \sqrt{400} }}$

Also don't forget to write "plus or minus" symbol when we are solving a quadratic equation by squaring both sides.

$\large{x = \pm{20}}$

Which symbol creates a true sentence when x equals 3?

Marta_Voda [28]

Hi <span>Tysona90!
Let's write it with the X as a 3
8*3-4*3_7(10-3) Now let's solve it 8*3 is 24 and 4*3 is 12 so then we do 24-12 which is 12. So now we have 12_7(10-3) so let's solve the other half which is 10-3 is 7 times 7 (since parenthesis can also mean multiplication) which is 49 so we now have 12_49 which means the answer is A.
Hope this helps!</span>
