Sentences with errors in parallel structure have conflicting tense and structure. The correct answer is C.
Lily has set a goal that she has wanted to accomplish for years: she is going to compete in a triathlon.
Answer:
24x^(2)Y
Explanation:
Prime factorization of 12 = 2 x 2 x 3
Prime factorization of 3 = 3
Prime factorization of 8 = 2 x 2 x 2
Compute a number comprised of factors that appear in at least one of 12, 3, 8, which are 2, 2, 2, 3.
Multiply them = 2 x 2 x 2 x 3 = 24
Add in the letters with the biggest value to the number aka x^(2) and Y.
Therefore having 24x^(2)Y.
