Answer:

4y^{2}+3y

Step-by-step explanation:

First you need to distribute the values.  

(4y+3)(2y) Using the "Rainbow Method" to multiply the polynomials  

You Should get  

8y^{2}+6y  

Since this is the area of the rectangle and we need to find the area of the shaded region you need to dived 8y^{2}+6y in half because the shaded region is half of the rectangle.  

8y^{2}+6y/2  

Doing this you will get  

4y^{2}+3y

Based on the order of operations, which shows the first step in simplifying this expression? 16/2+6(7+4x5)
Montano1993 [528]

Answer:

\frac{16}{2}  + 6(7 + 20)

Step-by-step explanation:

The given expresion is:

\frac{16}{2}  + 6(7 + 4 \times 5)

We want to find the first step in simplifying the above expression based on order of operations.

We use PEDMAS, so we deal with parenthesis first.

Within the parenthesis, we still need to multiply first to get:

\frac{16}{2}  + 6(7 + 20)

Help me please im giving good feedback!
Delicious77 [7]

Answer:

Area of bigger rectangle = length x breadth = 12 x 9 = 108 square cm

Area of small rectangle = length x breadth = 8 x 5 = 40 square cm

Area of the shaded region = Area of big rectangle - Area of small rectangle

                                         = 108 - 40 = 68 square cm
