Area of rectangular barn = 200 (sqft)
Length= Width + 10
Length x Width = 200 ==> (Width+10)Width = 200
Width² +10Width -200 = 0===> width = 10 ===> length = 20
220
from 218 the 1 is in the tens column. this is the figure that needs to be rounded.
using the following rule
If the digit after the 1 is ≥ 5 then round 1 up to 2
If the digit after the 1 is < 5 then the 1 remains as 1
here the digit after the 1 is 8 so the 1 in the ten's column becomes 2 and the 8 is replaced by 0
218 ≈ 220 ( to the nearest ten )
D sounds like the best answer math can be hard tho
Answer:
<u>17-(- 2 / 5j)</u>
Step-by-step explanation:
16 + (- 5 ) - 2/5j - 4/5 j + 6
\/ \/ \/
11- ( -2/5j ) + 6
From here you over the 6 over to the 11
11+6-(-2/5j)
\/
17-(-2/5j)
It can not be simplified farther I believe
