Answer:
157517.273607
Step-by-step explanation:
Area of the figure = 806.5 in²
Solution:
Length of the rectangle = 16 in
Breadth of the rectangle = 9 in
Area of the rectangle = length × breadth
= 16 × 9
Area of the rectangle = 144 in²
Base of the triangle = 31 in
Height of the triangle = 20 in
Area of the triangle = 
Area of the triangle = 310 in²
Parallel sides of the trapezium = 16 in and 31 in
Height of the trapezium = 35 – 20 = 15 in
Area of the trapezium = 
Area of the trapezium = 352.5 in²
Area of the figure = Area of rectangle + Area of triangle + Area of trapezium
= 144 in² + 310 in² + 352.5 in²
Area of the figure = 806.5 in²
12) This one would be (b) because if you were reading it out loud it would be 2 is less than 3x, and 3x is greater than 5.
13) To make this easier for you I would change everything to a decimal.
Peaches: 3.25 pounds
Mangos: 4.35 pounds
Since the peaches are .89 per pound you times
3.25(.89)=2.8925 (which rounds to 2.89)
Since the magpies cost 1.26 per pound you would times
4.375(1.26)=5.5125 (rounds to 5.51)
Then 5.51-2.89=2.62
So the answer is A
14)3x is greater than or equal to nine
In this case x would have to be three or greater. So the answer would be B
15) The answer is B
16)c
— -5=20
2
You first get rid of your constant which in this case is -5, so you add 5 to both sides.
C
— -5=20
2
+5 +5
Then you would get
C
— =25
2
Now you want to try to get the variable alone, so you cancel the twos out, what you do to one side you have to do to the other.
2 C
— =25(2)
2
C=50
The answer is D
T(n) = 0.2n
Hope I helped!
Let me know if you need anything else!

Subtract 2 from both sides and you get 2x>2, dived 2 from both sides to isolate the variable. Then you get x>1 :)
