**Answer: There are 456975758 plates that the state can issue.**

**Step-by-step explanation:**

Since we have given that

Number of letters = 4

Number of numerals = 3

And 242 letter arrangements are not allowed.

As we have 26 letters i.e A-Z

and numerals i.e, 0-9

So, the number of plates would be

So, the restricted letters deducting would be

**Hence, there are 456975758 plates that the state can issue.**

**Answer:**

B.x=94, y=105

**Step-by-step explanation:**

Let's start with x

x is places in a supplementary angle

supplementary angles are equals to 180 so

180-86=94

Next the y

interior angles have a formula 180(n-2)

so there are 4 sides

180(4-2)

180(2)

=360

add all the angles then subtract it to 360

72+89+94+y=360

255+y=360

y=360-255

y=105

Find the factors of 3, which are 1, 3 or -1, -3, and 24, which can be 1,24; 2,12; 3, 8; 4, 6, negative and positive, and write them this way: factors of 3 to the left, factors of 24 to the right.

then multiply diagonally and add up the products. Keep trying different pairs of factors till you make a -17

1 -3

3 -8

1*(-8) + 3(-3) = -17

so (n-3)(3n-8) is the factored form of the expression
