Answer:
1440
Step-by-step explanation:
3(x+4)(x+1)(x+2)(x-2)
Let x= 4
3(4+4)(4+1)(4+2)(4-2)
Evaluate each parentheses
3 ( 8) (5)( 6) (2)
Multiply
1440
If you meant
3(x+4)(x+1)
= 3(4+4)(4+1) = 3 * 8 *5 = 120
(x+2)(x-2)=(4+2)(4-2) = 6 *2= 12

Answer: Stratified Random Sampling
Step-by-step explanation:
STRATIFIED RANDOM SAMPLING in statistics invoices dividing a population into subgroups known as strata. These strata are based on shared characteristics in a group which in this case is the location of primary residence. This method is used to highlight differences in population as opposed to simple random sampling which gives all members of the population an equal chance of being represented.
<u>7x + 3 = 9x - 7</u>
Subtract 7x from each side: + 3 = 2x - 7
Add 7 to each side: 10 = 2x
Divide each side by 2 : <em>5 = x </em>
