Step-by-step explanation:
<u>Numbers:</u>
<u>Let's see which option is correct:</u>
-1.1 is a rational number, 4.5 and -6 are integers, and 12 is a whole number.
- 4.5 in not an integer, it is incorrect
-1.1 and -6 are rational numbers, 12 is an integer, and 4.5 is a whole number.
- 4.5 is not a whole number, this is incorrect
4.5 and -1.1 are rational numbers, -6 is an integer, and 12 is a whole number.
12 is a rational number, -1.1 and -6 are integers, and 4.5 is a whole number.
- -1.1 is not and integer, 4.5 is not a whole number, this is incorrect
The simplified form of the expression is -10x - 16
<h3>Factorizing expressions</h3>
Given the expression -2(5x + 8)
In order to factorize the expression, we will use the distributive property. Distribute -2 over 5x and 8 to have:
Step 1: Distribute -2 to 5x and 8
-2(5x + 8) =-2(5x) -2(8)
Simplify
-2(5x + 8) = -10x - 16
Hence the simplified form of the expression is -10x - 16
