Question

25pt solve this

|a+3|+|a+4| if a=[-4;-3]

Answer 1

Explanation:

|a+3|+|a+4|

If a = [-4,-3]

To solve the equation when a is -4

`so \: we \: substitute \: a \: with \: - 4 \: then \: we \: solve \\ (a + 3) + (a + 4) \\ ( - 4 + 3) + ( - 4 + 4) \\ ( - 1) + (0) \\ = - 1`

That's the answer when a is -4

Now we solve for when a is -3

`(a + 3) + (a + 4) \\ ( - 3 + 3) + ( - 3 + 4) \\ (0) + (1) \\ = 1`

That's the answer when a is -3

Answer 2

1 and -1

Explanation:

if a = -4 the equation= -1

if a = -3 the equation = 1
