Evaluate the following expressions for x = 2.

1. -9.2(4-2)= -18.4

2. -36.8+9.2(2)= -18.4

Step-by-step explanation:

just plug in 2 in stead of x

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

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
