(x-9) (x+2)=x²+2x-9x-18=x²-7x-18
Hi there! To round 10.95 to the nearest tenth, we find the number in the tenth place, which is 9 and look one place to the right. Round up if the number is greater than 5 or equal to 5 and round down if its less than 5.
The answer is 11.0 or just 11.
<em>Ed: Explanation below.</em>

11.00
10.99
10.98
10.97
10.96
10.95 Look at the 9. Then look to the right. Do I round up or down?
10.94
10.93
10.92
10.91
10.90
If the number is greater or equal to 5, you round up. If the number is smaller than 5, you round down. 9 is greater than 5, so we round up.
Therefore, the answer is 11.
Given:
The scale of a map is
.
The distance between two buildings is 60 miles.
To find:
The distance between the given building on the map.
Solution:
We have,

It means, 80 miles in real life =
on the map.
1 mile in real life =
on the map.
60 mile in real life =
on the map.
=
on the map.
=
on the map.
Therefore, the buildings are
apart on the map.
Answer:
±3i
Step-by-step explanation:
Given the value ±√-9, we are to express the value using the imaginary number 'I'
±√-9 = ±√9×-1
= ±√9 × √-1
In complex number, √-1 = i
The expression becomes;
±√9 = ±3 × i
±√9 = ±3i
Hence the value in simplified form is ±3i
Since we need a point that divides K-->J into two segments in a 1:3 ratio, let's flip it to a 3:1 ratio in the J-->K direction. That means that this point is 3/(3+1) = 3/4 of the way up line JK.
Let's take 3/4 of the x of K (plus the 1 for the x of J):
3/4×(9 - 1) + 1 (because the beginning ofvthe line, at J, has an x of 1)...
3/4×(8) + 1 = 6 + 1 = 7
Therefore the answer is C) 7
