Answer:
7%
Step-by-step explanation:
all of the above A, B, and C are correct.
81 m²
A = 6*10 + 7*6/2
= 60 + 7*3
= 60 + 21
= 81 m²
0
2 + 2 = 4 and then 4 - 4 = 0
109 - -37 = 146
since you are subtracting a negative, the negative number and the sign cancel each other out. So all you have to do is add.
