Answer:4x^2-9
Step-by-step explanation:
By using the FOIL method we multiply 2x by 2x, 2x by -3, 3 by 2x, and 3 by -3.
After doing this we are left with 4x^2-6x+6x-9
The -6x and 6x cancel each other out leaving just 4x^2-9
Either 700000 or seven hundred thousand

Step-by-step explanation:
Answer:
a) The probability that a 5 is rolled is
b) The probability that a number greater than 2 is rolled is
Step-by-step explanation:
a)
On this cube, there are sides labeled 1-6. Only one of the six sides is labeled 5. This means that the probability of rolling a 5 is
b)
Again this cubes has sides labeled 1-6.
The numbers on the cube that are greater than 2 are 3,4,5, and 6. This is 4 of the 6 sides of the cube. when simplified is
