When integrating a long chain of functions, we can integrate each term seperately and combine them. Let us now integrate:∫21x 6 dx = 21∫x 6 dx. Using the Power Rule [∫x a dx = (x a+1 /a+1)], we can say that ...

Rectangle A has a length of 3y cm and a width of 2x cm. Rectangle B has a length of (y + 4)cm and a width of (x + 6)cm. Rectangle A has a perimeter of 94cm and Rectangle B has a perimeter of 56cm. Solve x and y and calculate the areas of each rectangle.

To calculate the perimeter of a shape, you have to add up the lengths of all of its sides. So:A: 3y + 2x + 3y + 2x = 94 ; B: (y + 4) + (x + 6) + (y + 4) +(x + 6) = 56Simplifying both equations give:4x + 6y =...
