Answer:
1. (2x^2+x-1)
Step-by-step explanation:
expanding (2x^2-1)^2. multiplying (x-2) (1-2x)
= 4x^2-4x+1. = x-2x^2-2+4x
= -2x^2+5x-2
(4x^2-4x+1-2x^2+5x-2)
=2x^2+x-1
For example if we have 7/10 we have one 0 in the denominator so we move the decimal spot 1 to the left
So:
7.0 becomes 0.70 or .7
To make a decimal into a fraction:
0.32
Just add two zeros to the right and that means 2 0's will be added in the denominator
so:
0.32
32.0/100 or 32/100
Hope that helps :)
25% chance because there are 8 total “slices” and there are 2 A’s.
2/8=1/4=25%
