Answer:
2x² + 12x + 10
Step-by-step explanation:
Area of a rectangle = width x length
Therefore,
Area = (x + 1)(2x + 10)
Expand the brackets: 2x² + 10x + 2x + 10
Combine like terms: 2x² + 12x + 10
A quadratic expression is an expression with the variable with the highest power of 2
-8r on both sides; -2r=16; now divide by -2; r=-8
Answer: 20 ways
Step-by-step explanation:
Given: There were 5 women, 4 men, 6 girls and 7 boys at a birthday party.
i.e. Number of women = 5
Number of men = 4
According to the fundamental counting principle , we have
(Number of women ) x (Number of men)
= 5 x 4
= 20
Hence, 1 woman and 1 man can be chosen in 20 ways to take coats.
Answer:

Step-by-step explanation:
Assume a pentagon has equal length where a be the side of the pentagon and r be the apothem of the pentagon.
Given:
Sides of pentagon 
apothem of pentagon 
The area of the pentagon formula is given below.

Where b = length of the base or side
And h = height of apothem
Now, we substitute side and apothem length in above formula.


Therefore, the area of the pentagon is
