10) Simplify the following expressions
-|-4|+|-7.2|
a)-11.2
b)3.2
c)11.2
d)-3.2
11) What is the opposite of
12)
13)
14)

Answer 1

Answer: (10) 3.2 (11) option 2 (12) option 4

(13) Distributive (14) Associative

Explanation:

10) "Absolute value" makes the number positive.

- |-4| + |-7.2|

= - 4 + 7.2

= 3.2

11) "Opposite" changes the sign.

the opposite of
`-\sqrt{(2)/(5)}` is
`+\sqrt{(2)/(5)}`

12) Reciprocal means "flip" the fraction

the reciprocal of
`-\sqrt{(2)/(5)}` is
`-\sqrt{(5)/(2)}`

13) a(b + c) = ab + ac is the Distributive Property

`-\sqrt5(2+X)`

=
`-\sqrt5(2) -\sqrt5(X)`

=
`-2\sqrt5 -X\sqrt5`

14) a · (b · c) = (a · b) · c is the Associative Property

`20(4\sqrt5)`

=
`(20\cdot 4)\sqrt5`
