Answer:
24
Step-by-step explanation:
Let's do the smaller parts at the edge.
The formula for a triangle is 1/2bh
The base is 3 the height is 4
3 times 4 is 12
12 divided by 2 is 6
Since there are two of the same triangle on the edge both of the triangle's area is 6 which is 12
No for the upper triangle, the base is 6 and the height is 4
4 times 6 is 24
24 divided by 2 is 12
12 plus 12 is 24
The answer is
The area of the shaded parts of the triangle is 24 in^2
Hope this helps!
Answer:
Friday night.
Less expensive.
Step-by-step explanation:
Cost of 1 ticket on Friday = 48/3 = $16.
Cost on Saturday = 36 / 2 = $18.
Now 96 / 6 = $16 so the brother and his friends will have to go to the Friday concert. From the above costs we see that they did buy the less expensive ticket.
First, let's make a two-way table using a matrix:
![\left[\begin{array}{cccc}&Tennis&No&Total\\Male&7&5&12\\Female&9&6&15\\Total&16&11&27\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7D%26Tennis%26No%26Total%5C%5CMale%267%265%2612%5C%5CFemale%269%266%2615%5C%5CTotal%2616%2611%2627%5Cend%7Barray%7D%5Cright%5D%20)
A.
B.
The area of the outer square = (x+5)² = x² + 10x + 25
The area of the inner square = (x-2)² = x² - 4x + 4
The area of the shaded region = (x² + 10x + 25) - (x² - 4x + 4)
= x² + 10x + 25 - x² + 4x - 4
= 14x + 21 square units
