Step-by-step explanation:

Clara writes the equation (x – 13)(x + 8) = 196 to solve for the missing side length of a rectangle represented by the factor x + 8.

LEts solve the equation for x

WE multiply the left hand side using FOIL method

Combine like terms

Now we factor the left hand side

Product is -300 and sum is -5,

Now set each factor =0 and solve for x

Length cannot be negative so we take only x= 20

the missing side length represented by x + 8
