Use the grouping method to factor this polynomial completely.
2x + 6x2 + 5x+15

Step-by-step explanation:

The correct expression is

To use the grouping method, we need to group factorable monomials using parentheses. Notice that 2x and 6x² have a common factor 2x; similarly, 5 and 15x have a common factor 5. We can group each pair of monomials using parenthesis, and then factor each one.

Now we can factor the common monomial :

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units
