31-27+12-23-(-25)+(-6)= 12
Answer:
20 unit²
Step-by-step explanation:
A trapezium is given to us on the grid and we need to find out the area of the trapezium . In order to find the area , we need to find the measure of the parallel sides and the distance between the parallel sides.
<u>From </u><u>the</u><u> </u><u>grid</u><u> </u><u>:</u><u>-</u>
Now here we got the two parallel sides of the trapezium and the distance between the two parallel sides. Now we can find the area as ,
<em><u>Step-by-step explanation:</u></em>
FIRST, we want to understand every property:
Associative Property: The associative property states that you can add or multiply regardless of how the numbers are grouped so (5 + 4) + 3 = 5 + (4 + 3)
Commutative Property: Commutative is the one that refers to moving stuff around so 3 + 2 = 2 + 3
Additive Inverse Property: This is the number that when added to the original number, equals 0 or it's the opposite of the number so 5 <- is the original number and -5 <- is the additive inverse.
Simplify: Is just to add like terms, and make the equation the simplest.

Answer:
548 miles
Step-by-step explanation:
O.25m + 210 = 347
0.25m = 347 - 210
0.25m = 137
m = 137/0.25
m = 548
Sometimes there is no apparent way to factor it by hand /(the factors are decimals or imaginary). To try and factor these problems is nearly impossible in your head.
