Answer:

a) 4\left(3x+2\right)-2=12x+6

b) 20b-16= 4\left(5b-4\right)

Step-by-step explanation:

a) To simplify the expression you must:

Expand 4(3x + 2):

Apply the distributive law: \:a\left(b+c\right)=ab+ac

a=4,\:b=3x,\:c=2\\\\4\left(3x+2\right)=4\cdot \:3x+4\cdot \:2

Simplify 4\cdot \:3x+4\cdot \:2= 12x+8

12x+8-2

Subtract the numbers: 4\left(3x+2\right)-2=12x+6

b) To factor the expression 20b - 16 you must:

Rewrite 16 as 4\cdot 4 and 20 as 4\cdot 5

20b-16=4\cdot \:5b-4\cdot \:4

Factor out common term 4

20b-16= 4\left(5b-4\right)

How do you determine whether a sum will be positive, negative, or 0 when adding a positive and a negative integer?
professor190 [17]
If the integers have the same absolute value ... they're the same number
but with different signs ... then their sum is zero.

Example:    (plus) 927 added to (negative) 927  =  zero


If the integers have different absolute values ... they're different numbers with different
signs ... then their sum has the same sign as the one with the bigger absolute value.

Examples:

==>   (plus) 92 added to (negative) 91
         92 and 91 are 1 number apart on the number line.
         The positive number is bigger than the negative number.
         So the sum is  +1 . 

==>    (plus) 35 added to (negative) 37
          35 and 37 are 2 numbers apart on the number line.
          The negative number is bigger than the positive one.
          So the sum is  -2 .
