SVEN [57.7K]
There are many ways to work this out. One way could be:

Add up:
1/4 + 1/4 + 1/4 = 3/4

Find 3/4 of 8 so;
8 / 4 = 2
2 x 3 = 6

Find what's remaining:
8 - 6 = 2

So Mr.Greg has sandwiches left.
Hope it helped :)

Find the area of the shaded region for the given figure in terms of x.
Vlada [557]

Answer:

Area of the shaded region = (6x + 3)

Step-by-step explanation:

Area of the shaded region = Area of the large rectangle - Area of the small rectangle

Area of the large rectangle = Length × Width

                                             = (x + 2)(x + 2)

                                             = (x + 2)²

                                             = x² + 4x + 4

Area of the small rectangle = (x - 1)(x - 1)

                                             = (x - 1)²

                                             = x² - 2x + 1

Area of the shaded region  = (x² + 4x + 4) - (x² - 2x + 1)

                                             = 6x + 3

Area of the shaded region = (6x + 3)
