Answer:
7986 m²
Step-by-step explanation:
The figure is a trapezium with area (A) calculated as
A =
h (a + b)
where h is the height and a, b the parallel bases
Here h = 66, a = 102 and b = 140, thus
A =
× 66 × (102 + 140) = 33 × 242 = 7986 m²
Answer:
x=7
Step-by-step explanation:

now let’s put together the like terms


now we divide
By 
the result is

Answer:
1/5k-2/3j and -2/3j+1/5k
Step-by-step explanation:
This is because the sign of both of the terms stay the same and the fractions and variables stay the same for each term as well.
Answer: 
Step-by-step explanation:
To find the area of the shaded region, you must find the area of the larger rectangle [(x+10)×(2x+5)] and subtract the area of the smaller rectangle [(x+1)×(x+1)] from it.
First, you simplify the larger rectangle's area:
(x+10)×(2x+5) = 
Then, simplify the smaller rectangle's area:
(x+1)×(x+1) = 
Finally, subtract the smaller rectangle's area from the larger rectangle's area:

Therefore, the final answer is
.

False. Dilations increase the area and side lengths of a shape but the angles maintain the same measure.
