In the figure below cef is an equilateral triangle. points b, c and e are collinear; points a, c and f are collinear; g=40 degrees and k =45 degrees. find j

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

40 points. given: two congruent angles ∠c and ∠r are supplementary. prove: ∠r and ∠c are both right angles. it doesn't have to be exactly 10 rows.statements reasons1. 1. 2. 2. 3. 3. 4. 4. 5. 5. 6. 6. 7. 7. 8. 8. 9. 9. 10. 10.

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]
