HELP ASAP!!! WILL GIVE BRAINLEIST!!!

Answer:

The first question is (n*8) - 4

The second question is no.

Step-by-step explanation:

The first question, you add 8. The first is 1. 1 * 8 = 8 - 4 = 4.

Therefore, the equation is (n*8) - 4

The second question, you can plug in numbers. You can solve for a term.  -100 + 17 = -83. -83 is not a multiple of -4. -100 is not a term.

Which of the following numbers is not a perfect square?<br><br> 24<br> 25<br> 64<br> 100
stich3 [128]
Hi! 

A perfect square is the product of when a whole number is multiplied by itself

Ex:

6 × 6 = 36, 36 is the perfect square. 

The number that is being multiplied is the square root. 

So to find the correct answer for this question, let's use the process of elimination. 

100 = 10 × 10 so we can cross out 100

64 = 8 × 8 so we can cross out 64

25 = 5 × 5 so we can cross out 25

Now all we have left is 24, which is not a perfect square. 

Answer: A. 24

Hope this helps :)
