Which is a correct way of evaluating the expression 15x + 30x for x = 2?

How many heads would you expect if you flipped a coin twice? first, fill in the table below with the correct probabilities. hint: the sample space for flipping a coin twice is {hh, ht, th, tt}. a = b = c =

Solve the following: 12(x^2–x–1)+13(x^2–x–1)=25(x^2–x–1) 364x–64x=300x

Solve for b. ab + c= d b= a + old ob=allc-ch b= (d-c/a
