Answer:
B
Step-by-step explanation:
The side you have drawn in is 4√3 (calculate via pythagoras as √(8²-4²) = √48 = √16·3 = √4²·3 = 4√3)
So the area of the small triangle is 4*2√3 and the area of the small rectangle is 2*4√3. Together makes 4*2√3 + 2*4√3 = 16√3

Answer:
25/416
Step-by-step explanation:
Maybe you want to know the value of ...
(1 1/4)/(20 4/5) = (5/4)/(104/5) = (5/4)×(5/104) = (5×5)/(4×104) = 25/416
-3.5(2 - 3n) - 2.5n
= -7 + 10.5n - 2.5n
= -7 + 8n
The volume of the bedroom is 11 x 10 x 10 = 1100 cubic feet.
The volume of the den is double, so 1100 x 2 = 2200 cubic feet.
Divide the volume of the den by the height, since it is the same as the bedroom, this will give you the area:
2200 / 10 = 220 square feet.
Two sets of numbers that could equal 220 are 22 x 10 or 22 x 11
The room can be 20 ft by 10 ft or 22 ft by 11 ft and the volume is 2200 cubic feet.
Answer:
x = 12
Step-by-step explanation:
Here, we want to get the value of x
Looking at the angles of the shapes, we can see that the two figures are similar
When two figures are similar, the ratio of their corresponding sides are equal
Thus, mathematically, we have it that;
MN/PN = HJ/KJ
9/x = 6/8
9 * 8 = 6 * x
6x = 72
x = 72/6
x = 12
