For which nonnegative value of x is the expression 5+x

25-x^2
undefined?
explain steps and what the question means!

x = 5

Step-by-step explanation:

the expression is "undefined"  when the denominator is equal to zero

denominator =  25 - x²

Values of x where the equation is "undefined"

0 = 25 - x²

x² = 25

√x² = √25

x = ± 5

Nonnegative value of x where the equation is "undefined"

x = 5

Area of the rectangle = ( x²+12x+27)unit²

Step-by-step explanation: Length = x+3  Breadth = x+9

∴ Area of Rectangle = L×B

(x+3)(x+9) = x²+9x+3x+27 = (x²+12x+27) unit²
