Hello there!

Evaluate a²  for a = -4

The first step we need to do is replace a by -4

So we have (-4)²

Now what you have realize is that we need to multiply -4 by itself twice.

So it should looks like this:

-4 * -4

The rules says that when we have minus * minus, the answer is positive.

So we have -4 * -4 = 16

Answer: 16

I hope this helps!

Please let us know if you have other questions.

Abbi has $400 in $5 bills. If she has 38 bills, how many of them are $20?
Sergio039 [100]
F=5 dollar bills
t=twent dollar bills

38 total bills
f+t=38

400 in bills
400=5f+20t

we have
f+t=38
5f+20t=400
multipy first equation by -5 and add to second equation

-5f-5t=-190
5f+20t=400 +
0f+15t=210

15t=210

divide both sides by 15
t=14

subsitute
t+f=38
15+f=38
f=23
