Answer:
108 feet²
Step-by-step explanation:
Well we can just multiply the corresponding sides of Quadrilateral ABCD to fit Quadrilateral EFGH.
Line EF is 42 feet
Line FG is 18 feet
Line GH is 18 feet
Line HE is 30 feet
The perimeter of Quadrilateral EFGH is
30+18+18+42=
30+36+42=
66+42=
108 feet²
So here, I would first multiply 0.17777.... (Assume that that's x) by 10, then you get
10x = 1.777777...
And then subtract x from 10x and then you get 1.6.
So that means that
10x - x = 9x
and 1.7777... - 0.17777... = 1.6
So now to solve for x, divide both sides by 9
To get 1.6/9 = x
Or 16/90 = x
Or 8/45 = x
(That explanation made no sense)
Answer:
23b because a cancels out
Step-by-step explanation:
7/10 + (-17/20)
Make the denominators equal:
14/20 + (-17/20)
Add:
-3/20
