Which test should I take the SAT or the ACT?
I would recommend that you take both. Both tests are equally as challenging, however, some students perform better on one test compared to the other. However, while most schools don't have a preference on which you take some may. In terms of content covered by tests, the ACT has Scientific reasoning portion while the SAT does not. Both tests cover High School Math, Reading, and English (grammar) skills. When it comes to grading both test score differently. On the SAT You receive 1 point for every question answered correctly and no points are taken away for incorrect responses. Furthermore, the essay is graded on a scale of 1 - 4 by two graders. The scores are added for a total possible score of 8. On the ACT You receive 1 point for every question answered correctly and no points are taken away for incorrect responses. Furthermore, the essay is graded based on four different domains; Ideas and Analysis, Development and Support, Organization, and Language Use and Conventions. Each domain is graded on a scale of 1 - 6 by two graders. The scores are added for a total possible score of 12. Furthermore, the final grade for the essay is the sum of the scores on all four domains with a maximum score of 36
How do I solve for x in the quadratic equation 2(x^2) + 7x - 15 = 0
First, you must factor the quadratic equation: Since 2(x^2) can be factored to x and 2x Thus 2x times some number plus x times a different number must be equal to 7x which we can find by factoring the coefficient -15 The coefficient -15 can be factored 4 different ways 1. 1*(-15) 2.(-1)*15 3. 3*(-5) 4.(-3)*5 Since 2x time 5 plus x times -3 equals 7x The quadratic equation 2(x^2) + 7x - 15 = (2x-3)(x+5) = 0 Since 0 times some number is equal to 0 We can solve the quadratic equation by finding an x that will solve for 0 Thus if 2x-3 = 0 and x+5 = 0 then we can solve algebraically for x 2x - 3 = 0 ---> 2x = 3 ---> x = 3/2 x + 5 = 0 ---> x = -5 Thus 2(x^2) + 7x - 15 = 0 when x is equal to 3/2 and -5
Which essay should I write A, B, or C?
It depends on the university your applying to. I would recommend that you write all three of them. Some universities may take non-required essays into considering when deciding whether or not to admit you. Furthermore, writing all three essays may allow you to save time in the future if you decide to apply to more universities with different essay requirements.
