4 0

Answer:

0

Step-by-step explanation:

Apply Only the Outside and Inside Method of the Foil Method.

7 \times  -  \frac{1}{2}  =  - 3.5x

\frac{1}{2}  \times 7x = 3.5x

Add them together

- 3.5x + 3.5x = 0

So our b value is 0.

Vitek1552 [10]

Answer:

32

Step-by-step explanation:

No of desks along  length of the rectangle = 7 as it is 7 rows wide.

No of desks along  breadth of the rectangle = 7 as it is 5 rows long.

Total number of students is product of these two numbers.

So number of students = 35.

But three desks are empty.

Total students = 35- 3

                         = 32.
