Answer:
Step-by-step explanation:

If y is 16 the x is 2y+3=2•26+3= 51
i think this is the answer i forgot this but this is so easy.
-x^2
Is that x times -x?
positive times a negative is negative
and you add the exponents when multiplying like base
Since there are 26 black cards (1/2 of 52) and 2 black twos (one for each suite, and there are 2 black/red suites), we can use the same logic to get that there are 2 black eights. 2+2=4, and since there are 52 cards, you have a 4/52 or 1/13 (we get this because 4 goes into 52 13 times) chance of getting a black 8 or 2.
