Answer:
x<3 and x<5
Step-by-step explanation:
Given the quadratic inequality x² - 8x + 15 <0, to get the solution set for the inequality, the following steps must be followedStep 1: Factorize the quadratic expression
x² - 8x + 15 <0
x² - 3x - 5x + 15 <0
x(x - 3) - 5(x - 3) <0
(x -3)(x -5)< 0
x -3<0 and x -5<0
x< 3 and x< 5

Answer: 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
