At carter's birthday party his mom made a cake in a rectangular shape. the length of cake is 8 cm and width of cake is 6 cm. if she wants to add 1 cm of cream around the cake, what will be the perimeter and area of the rectangle cake?

Perimeter of rectangular cake = 36 cm

Area of rectangular cake is 80 square cm.

Step-by-step explanation:

Length of the cake = 8 cm

Width of cake = 6 cm

Since we are given that she wants to add 1 cm of cream around the cake

So, Length becomes: 8+1+1 =10 cm

Width becomes: 6+1+1= 8 cm

Perimeter of rectangular cake =

                                                  =

                                                  =

                                                  =

Thus the perimeter of rectangular cake = 36 cm

Area of rectangular cake =

                                          =

                                          =

Thus the area of rectangular cake is 80 square cm.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
