help!@!@! neeed help again lol?

Question

Evaluate the problem.
1. -4 |-4|
2. -8 x |2|
3. |5| - |-5|
4. |x| - |-x|
5. 0 |-6|
6. |3 - 5 + 7|
Evaluate, given a = 5, b = -3, and c = -2.
1. |a + b|
2. |a + b - c|
3. |-a^2|
4. |bc|
5. |c^2 + b^2|

Answer 1

1. -4 |-4|=-16
2. -8 x |2|=-16 (if x is for multiplication)
3. |5| - |-5|=0
4. |x| - |-x|= if x>0 then 0 else -x-x=-2x
5. 0 |-6|=0
6. |3 - 5 + 7|=5
Evaluate, given a = 5, b = -3, and c = -2.
1. |a + b|=2
2. |a + b - c|=4
3. |-a^2|=25
4. |bc|=6
5. |c^2 + b^2|=29

Answer 2

1. -4 |-4|=-16
2. -8 x |2|=-16 (if x is for multiplication)
3. |5| - |-5|=0
4. |x| - |-x|= if x>0 then 0 else -x-x=-2x
5. 0 |-6|=0
6. |3 - 5 + 7|=5
Evaluate, given a = 5, b = -3, and c = -2.
1. |a + b|=2
2. |a + b - c|=4
3. |-a^2|=25
4. |bc|=6
5. |c^2 + b^2|=29

Answer 3

-4x4=-16
-8x2=-16
5-5=0
X-X=0
0x6=0
The absolute value of 3+7-5=5

All positive as absolute value is always +
5-3=2
2+2=4
|-5x5|=|-25|=25
-3x-2=6
-2x-2+-3x-3=13

Answer 4

1) 0
2) -16
3) 0
4) 0
5) 6
6) 5

1) 2
2) 4
3) 25
4) 6
5) 13

Answer 5

let me explain u the function
|x|= x if x>0
-x if x<0
for example |5|=5 cause 5>0
and |-5|=-[-5] cause -5<0
or u can understand this function in this way dat it gives only positive value.
so try urself now. nd if u dont get let me know abt it
