Is absolute value of a and b is equal to the absolute value of a plus the absolute value of b?

Only when a and b have the same sign (or when a or b equals 0). Here are some examples:
|2+4|=|2|+|4|--> |6|=|6|--> 6=6 TRUE
|(-1)+(-3)|=|(-1)|+|(-3)|--> |(-4)|=1+3--> 4=4 TRUE
|3+(-6)|=|3|+|(-6)|--> |(-3)|=3+6--> 3=9 FALSE

What are the absolute value of 5.24?
what is the absolute value of 5.24
What is the value of k when the equation x squared plus 2kx plus 10x plus k squared plus 5 equals 0 has equal roots?
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
What is b plus 3?
Depends on what the value of B is. It can be written as b+3
What does x-a plus x-a plus b equal?
(x - a) + (x - a) + (b) = 2 (x - a) + (b) = x - a + x - a + b = 2x - 2a + b
Is a squared plus b squared the same as a plus b squared?
No. If you expand (a + b)2 you get a2 + 2ab + b2. This is not equal to a2 + b2
How can you write the expression a plus b plus a-b in equivalent form not involving absolute value.?
The expression (a+b) + (a-b) can be rewritten as a + b + a - b = 2a.There is no need to use absolute value.
What does 34a plus 10b equal?
That depends what the value of a and b are.
What does A plus B plus C equal?
That depends on the value of the variables (A, B, and C). It can be anything.
How does the absolute value of the sum relate to the absolute value of the two numbers being added?
|a + b| ≤ |a| + |b|
How A plus B plus C plus D plus 80 plus 90 equal to 100 what is the value of A B C and D?
If a + b + c + d + 80 + 90 = 100, then a + b + c + d = -70.
Why isnt the absolute value of a over b always a over b?
the absolute value of a over b is not the invers. it is a posative number of a over b. when you see the absolute value, just change it to a posative number. if it is posative, you have your answer.
What is triangular inequality of complex number?
The absolute value of the sum of two complex numbers is less than or equal to the sum of their absolute values.
What does b plus a plus b-a equal?
b + a + b - a = 2b
According to the Boolean algebra 1 plus A plus B plus C is equal to?
1. With boolean algebra, 1 + n is always equal to 1, no matter what the value of n is.
Is the absolute value of the sum of two numbers equal to the sum of the absolute values of the numbers?
NO! abs(2-2)=0 NOT equal to abs(2)+abs(-2)=4 - The above is technically correct, though the more thorough answer is as follows; no because the absolute value of the sum is LESS THEN OR EQUAL TO the sum of the absolute values. The simple proof the the fact that |A+B|<=|A|+|B| is called the triangular inequality. When A and B (or for that matter an infinite number of them) are both positive (or all) or both negative (or all) then they inequality is actually equal, if however any of the numbers have different signs then any other number, the inequality is less then.
What is the greatest comm an factor of B and B?
