Answer:

7x4+2x3-4x2-5

Step-by-step explanation:

We will start solving this question by opening the bracket first

So let's solve

(7x4+2x3-3)-(4x2-9x+2)

7x4+2x3-3-4x2+9x-2

Collect like terms

7x4+2x3-4x2-3-2

7x4+2x3-4x2-5

So the final answer is 7x4+2x3-4x2-5

Can someone please help me?
Oliga [24]
1/36 because you have 36 different possibilities when rolling it twice and getting and a 4 then a 6 is only 1 possibility out of the 36
1/4 because there is 3/6 chance on one roll and second roll
We said with 2 rolls there is 36 possibility (6x6)
So 3x3=9 which the amount of possibility to get a even number
9/36 simplify is 1/4 (divided by 9 the top and bottom)
Hope this helps!
