4. Rewrite each numeric expression using the Distributiv Property and the GCF.
a. 56 + 42
b. 54 + 84

a. 7(8+6)

b. 6(9+14)

Step-by-step explanation:

I found the GCF first and then divided each one to seperate

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
