please² help me

Mathpapa and Symbolab help btw

Step-by-step explanation:

1.x=4+2√5 or x=4−2√5

2.x=−6+4√2 or x=−6−4√2

3.Go to Mathpapa

4. No solution

5. Go to Mathpapa

6.x=5/4 or x=-3

7.Go to Mathpapa

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

i think that you should ask google for the answer to that problem because if we don't know it google does
