Answer= 1/4 7+6+11= 24 Green =6/24 Simplifies to 1/4, by division by 6.

Final Answer: a² +3a -18 Using FOIL (First, outside, inside, last) we multiply the terms in the brackets together. First: 3a multiplied by a = 3a²  Outside: 3a x 3 = 9a Inside: -6 x ...

y = 4x³ To differentiate you must find dy/dx. To calculate dy/dx, look at this example using just letters from algebra: y = ax^b dy/dx = (ab)x^(b-1) As you can see, to calcu...

Acceleration is the rate of change of velocity, so we subtract the final velocity from the initial velocity and divide it by the time taken for the change. In this case the acceleration i...
