|3.5| = 3.5
Any negative or positive number will always have an absolute value that is positive.
For example, | -3.5| = 3.5
3.5 can also be expressed a fraction.
3.5 * 2/2 = 7/2
Answer:
60 degree
Step-by-step explanation:
Here all sides of this triangle are equal, which means it is an equilateral triangle.
In an equilateral triangle, all the angles are equal and are 60 degrees to satisfy angle sum property.
x - y = 30
x - 15 = 30
+ 15 + 15
x = 45
(x, y) = (45, 15)
Let's see if we can't be logical here......Pick a formula and see what it yields. For example, choose D.
For n = 1 ---> -1 x 4^1 ----> -1 x 4 = -4, when the correct value is 1. Therefore D is out.
Try C. For n = 1 ---> 1 x 4^(1-1) ---> 1 x 4^0 ----> 1 x1 ---> 1, So it is correct for n =1. How about
n=2? 1 x 4^(2-1) = 1 x 4^1 = 1 x 4 = 4, when the correct answer is -4. Therefore C is out
I'm sure you can do the remaining two choices....
