Answer:
OK so you didnt put which numbers, but here is how you solve for area. Say if the legnth is 4 and the widght is 6. you have to do legnth times witgh, it this case 6x4 area is 24. Lxw=a
Step-by-step explanation:
You can't simplify this further but can convert it to Trignometric form.
2(cos(pie/6)+ísin(pie/6))
Let's read through this and make an equation:
? ("number")
? / -7 ("quotient of a number and -7")
(? / -7) - 2 ("decreased by 2")
<span>(? / -7) - 2 = 10 ("is 10")
</span>
Now we can solve:
<span>(? / -7) - 2 = 10
</span><span>? / -7 = 12
</span>? = -84
The number is -84
A and B, though B would be the best choice, because they all have an edge that is straight.
