Question

Please help! I'm not quite understanding this.

Answer 1

d.) 21

Step-by-step explanation:

Rules:

• -|a| = -a

• |-a| = a

• x = |a| then x = ±a

Solve:

`\rightarrow \sf (4|a|)/(2) + |a-3|`

[insert a = -6]

`\sf\rightarrow (4|-6|)/(2) + |-6-3|`

[simplify the following]

`\sf\rightarrow (4(6))/(2) + 9`

`\sf\rightarrow 12 + 9`

`\sf\rightarrow 21`
