Answer:
D) 35x³ - 16x² + 44x - 48
Step-by-step explanation:
(5x2 + 2x + 8)(7x – 6) = (5x2 + 2x + 8)* 7x + (5x2 + 2x + 8)*(– 6)
= (5x2*7x + 2x*7x + 8*7x) + (5x2*(-6) + 2x*(-6) + 8*(-6) )
=35x³ + 14x² + 56x - 30x² - 12x - 48
= 35x³ - 16x² + 44x - 48

Answer: 128.86cm²
Step-by-step explanation:
The circle is inscribed in the rectangle. To find the shaded portion, subtract he area of the circle from the are of the rectangle.
Area of the rectangle                                  =  11 x 12 
                                                                      =  132cm²
Area of the circle with radius of 1cm          =  πr²
                                                                      = 3.142 x 1²
                                                                      = 3.142cm²
Therefore , area of the shaded  region      = 132cm²  -  3.142cm²
                                                                     = 128.86cm²
