Been trying to figure it out for a while and when you answer tell me how to do it and explain

Jeyden will need 128 square feet of cardboard.

Step-by-step explanation:

Notice that you need to calculate the area of the figure. Now, the figure is formed by four equal rectangles and two equal squares. If you are not convinced of this fact, just check the shape of any box.

So, in order to calculate the total area , we only need to calculate the area of  one rectangle and the area of one of the squares . Because of the deductions of the above paragraph

.

From the figure we already know that the length of the rectangles is 6 ft. Also, notice that the height of the rectangles is given: 4ft. Then, square feet. Now, the squares have length 4 ft, so square feet.

Thus,

square feet.

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
