Answer:
Step-by-step explanation:
(2n - 3)(5n + 6) = 2n*(5n + 6) -3*(5n +6)
=2n*5n + 2n*6 -3*5n + (-3)*6
=10n² + 12n - 15n - 18
= 10n² -3n - 18
A.
To find a percentage of something, multiply by it's decimal. so 15% is 0.15
In c - 0.15c Louisa is taking the normal cost of a movie subscription and subtracting 15 percent of it off. hence the 15% discount.
We can rewrite this by skipping the subtraction part. If she's getting a 15% discount, you could say she is only paying 85% of it's normal price (100% - 15%). so put 85% in decimal and get 0.85c
Both expressions involve the same discount and both show that she is paying less than full price.
B.
They tell you the width is 16 feet. The length is 4% more than that. in other words the length is 104% the width. In decimal 100% is 1 and 4% is 0.04; 1 + 0.04 is 1.04.
1.04 * 16 = 16.64, which is the length.
Area (assuming the room is a rectangle) is length * width. so 16 * 16.64 whatever that equals is your area.
Hi!
We need to know the distance in a straight line from point N to the line LM.
There are 3 lines connecting N to LM. Two of them are diagonal and do not show the straight direct path to LM. One of them is a straight line right to LM. The length of it is 6.8.
The answer is 6.8.
Hope this helps!

Answer:
csc (0°) and sec (90°) are not defined.
Step-by-step explanation:
Given the options wehave to select the option which is undefinesd
First option: sec 45°
which is defined
Second option: csc(0°)
which is not defined
Third option: sec(90°)
which is not defined.
Hence, option 2 and 3 are not defined.
Answer:
C
Step-by-step explanation:
The point slope form of a line is 
. If the point is (2,5) then the equation will be 
. Only option C matches this equation.
