Answer:
2x+12=22
Step-by-step explanation:
the side we don't know is x and there are 2 and there are 2 lengths the same in a rectangle. we know one of them and it is 6 so we do 6 x 2 which is 12.
It equals 2(x+1) blah blah blah
there is 1 number 3 on a 6 sided die
so the probability or rolling a 3 is 1/6
