Answer:

10x2 + 2x + 13.

Step-by-step explanation:

10x2 + 3 - (-2x - 10) (Note you have to put the -2x - 10 in brackets).

= 10x2 + 3 + 2x + 10 (Distributing the negative over the brackets).

= 10x2 + 2x + 13.

Another fair dice is rolled 300 times. How many times would you expect it to land with a multiple of three on top? I need help t

Answer:

100 times

Step-by-step explanation:

multiples of 3 on a number cube are 3 and 6

probability of rolling a '3' or '6' is 1/6 + 1/6 = 2/6 or 1/3

1/3 x 300 = 100
