At first find the area of rectangle:
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:
\frac{(x+1)(x-3)}{2} =  \frac{x^2-2x-3}{2}
Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - (\frac{x^2-2x-3}{2})

Answer:

-10 points

Step-by-step explanation:

A game show awards 30 points for each correct answer and deducts 50 points for each in correct answer. A contestant answers 2 questions incorrectly and 3 questions correctly. What is his final score?

Let us say Initial number of points = 0

Hence,

He answers 2 incorrectly = 0 - 50 - 50

= -100

He answers 3 correctly =-100 + 30 + 30 + 30

His final score = -100 + 30 + 30 + 30

= -10 points

2476 adults watch a cricket match. The ratio men : women is 3 : 1 How many more men than women watch the match?
poizon [28]

he ratio of 3:1 involves 4 units. 3 men +1 woman.

Find how many people each unit represents:

    4units        2476 people

Therefore each unit represents 2476/4 = 619 people per unit

Now, take the ratio, and multiply up:

3:1  =>  3619:1619   =>   1857:619    You check this is right by adding the two fractions:

1857 men + 619 women = 2476 people therefore, we are correct

The number of men more than women = Number of men - Number of women

                                                       = 1857-619 = 1238 and that is your answer
