For what values of a are the following expressions true? |a+5|=−5−a

Mathematics
1 answer:
Fed [463]2 years ago
5 0

Answer:

a can be any real number less than equal to -5

Step-by-step explanation:

When a+5 is negative,

a + 5 = -(-5 - a)

a + 5 = a + 5

All values satisfy the equation

So a < -5

When a + 5 is greater than/equal to 0,

a + 5 = -a - 5

2a = -10

a = -5

a can be any real number less than equal to -5

HELP PLSSS I NEED THIS ASAP
Kamila [148]

Multiplying the linear expressions, the correct sequence is given as follows:

  • 5x(-3 -7x)
  • (5x)(-3) + (5x)(-7x)
  • -15x - 35x²

<h3>How are linear expressions multiplied?</h3>

They are multiplied applying the distributive property, in which all the terms are multiplied and the like terms are combined.

Hence:

5x(-3 -7x)

(5x)(-3) + (5x)(-7x)

-15x - 35x²

Hence the last option is correct.
