Alexis has a piece of red paper that is 4 centimeters wide. its length is twice its width. she glues a piece of blue paper on top of the red piece measuring 3 centimeters by 7 centimeters. how many square centimeters of red paper will be visible on top?

It is given:Alexis has a piece of red paper that is 4 centimeters wide. Its length is twice its width .If  length is 4cm then width = 4x2= 8cm.

Area of red paper= length x width = 4x8=32 square cm.

Alexis glues a piece of blue paper on top of the red piece measuring 3 centimeters by 7 centimeters.

Area of blue paper= 3x7=21 square cm.

Area of  red paper  that will be visible on top =32-21= 11 square cm.

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
