Answer:

Step-by-step explanation:

I'm not entirely sure what the question is, but I suspect the answer is not prime.

9x^2 - 4

factors into two factors  (3x + 2)(3x - 2)

Suppose x = 11 which is prime.

9*121 - 4

1085 which ends in a 5 so the expression is not prime.

In fact, the two factors are 3*11 + 2 = 35  and 3*11 - 2 = 31

31*35 = 1085

Can you help with 3 and 4

1. 7, you have to divide 10,885 by 1,555 and you get 7.

2. The equation that was given, 23+7 x 35 =  268

The way you get 268 is by multiplying first, so 7 x 35 = 245 then you have to add 23 to get 268.

I hope this helps you
