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}}

Answer:

A) 2x³+11x²+8x-16

Step-by-step explanation:

When you multiply s(x) by t(x) you get something like this:

s(x) \times t(x) = (2 {x}^{2}  + 3x - 4) \times (x + 4) \\  = 2 {x}^{3}  + 3 {x}^{2}  - 4x + 8 {x}^{2}  + 12x - 16 \\  = 2 {x}^{3}  + 11 {x}^{2}  + 8x - 16
