3a(12+5a-1a^²=
how do u do it

36a + 15a^2 - 3a^3

Step-by-step explanation:

I recommend using a calculator. It helps a lot.

If you're not going to do that, then all you do is multiply the 3a by the 12, tha 5a, and the 1a.

i'm sure goog can you get that answer

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
