Algebra
In order to solve this problem, you would have to distribute the negative (- sign) to the (x-2), making the problem x+2-x+2. The two x's would cancel out, therefore making the final answer 4.

The problem is 3x^2 - 26 + 35 (We have to factor it!) So, I did the problem, but I'm not sure how to write the final answer. This is what my problem looks like so far: 3x^2 - 26 + 35 (3x^2-21x)-(5x+35) 3x(x-7)-5(x+7) and this is where I have the problem. I know I need to put (...

I believe you stated the problem incorrectly. It does not accelerate FROM 96.56 km/h. That is the FINAL velocity after 4.3 seconds. It accelerates TO 96.56 km/h The average speed during acceleration at a constant rate (from a standing start) is half the final velocity.

Since we did not resolve your question, I am curious where you got this problem. Is it from a textbook? Is in an assignment problem? Just curious, since it obviously not a true statement.

If a triangle has an area of 50 square units and has angles that measure 15, 65, and 100 degress, find the length of the shortest side to the nearest tenth. Do not round till the final answer.
