Answer:
The area is 60 square units.
Step-by-step explanation:
Break it up into pieces.
The vertical rectangle on the left:
A = lw = 12*2 = 24 square units
The vertical rectangle on the right:
A = lw = 12*2 = 24 square units
The little rectangle in the middle:
A = lw = 6*2 = 12 square units
24+24+12 = 60 square units total
Answer:
x = 12
Step-by-step explanation:
The line joining the mid points of the non- parallel sides is parallel to the parallel sides and is equal to half the sum of the parallel sides, hence
5x - 20 = (2x + 6 + 4x + 2)
= (6x + 8) ← distribute, giving
5x - 20 = 3x + 4 ( subtract 3x from both sides )
2x - 20 = 4 ( add 20 to both sides )
2x = 24 ( divide both sides by 2 )
x = 12
Answer:
The diamond production is 2006 is expected to be 13.24 billion
Step-by-step explanation:
Here, we want to predict the diamond production is 2006
The equation to use is given in the question as;
f(x) = 0.39x + 10.9
Since x is the number of years after 2006, in this particular question, x will be 2006-2000 = 6
So f(6) = 0.39(6) + 10.9
f(6) = 2.34 + 10.9
f(6) = 13.24 billion
