First solve the area of the shaded triangle. 40 times 27 divided by 2 equals 540. Now subtract the area of the circle. The area of the circle is 36π because the radius is 6 and 6 squared times pi equals 36π. Finally subtract 36π from 540. The answer is (540-36π)².
14 x² + 6 x - 7 x - 3 = = ( 14 x² - 7 x ) + ( 6 x - 3 ) = = 7 x ( 2 x - 1 ) + 3 ( 2 x - 1 ) = = ( 2 x - 1 ) ( 7 x + 3 ) Answer: 1. GCF of the group ( 6 x - 3 ) is 3. 2. The common binomial factor is 2 x - 1. 3. The factored expression is: ( 2 x - 1 ) ( 7 x + 3 ).
