Answer:
7 units
Step-by-step explanation:
Answer:Although the Quadratic Formula always works as a strategy to solve quadratic equations, for many problems it is not the most efficient method. Sometimes it is faster to factor or complete the square or even just "out-think" the problem. For each equation below, choose the method you think is most efficient to solve the equation and explain your reason. Note that you do not actually need to solve the equation. a. x2+7x−8=0x
2
+7x−8=0, b. (x+2)2=49(x+2)
2
=49, c. 5x2−x−7=05x
2
−x−7=0, d. x2+4x=−1x
2
+4x=−1.
2.3 meters per second = 7.546 feet per second
Formula: multiply the value in meters per second by the conversion factor '3.2808398950087'.
So, 2.3 meters per second = 2.3 × 3.2808398950087 = 7.54593175852 feet per second.
