There are 4 multiplication equations that need to be done:1) (2x) x (9x) = 18x²2) (2x) x (-4) = -8x3) (5) x (9x) = 45x4) (5) x (-4) = -20Write this out as an equation: 18x² - 8x + 45...

The lock and key model of enzyme action describes how enzymes are specific for their substrates. The enzyme is the lock and the substrate is the key. Much how every key is specific for a lock, every enzy...

First we have to multiply 8 and 2 together to get 16. We then need to find all the factors for this number.These are:1 and 162 and 84 and 4 From these sets of factors, we have to find which has a differen...

We know that the turning point of this quadratic will be a minimum point because the coefficient of x2 is positive (1). To find the turning point, we must complete the square: y= (x-4)² -16 +10...

Parliamentry and Presidential systems are two of the most common governmental systems used. The two oldest and most prominent examples of these systems are the British and American systems respectively. T...
