An octagon has 8 sides. Each side is given as 2a + 1

Perimeter = 8(2a + 1)

as we all know ... an octagon has 8 corners / sides

and they told that each side is equal to 2a + 1

so we need to make an equation which will be 8 (2a+1)

ans now we need to multiply 8 with both 2a and 1

so, 8 ( 2a + 1 )

16a + 8

we cant do this further as its not "like"

so the answer is 16a + 8

If a 25 in. by 32 in. window has a wooden frame 2 inches wide surrounding it, what is the total area of the window and frame?

d1i1m1o1n [39]

Answer:

1044 sq. inches

Step-by-step explanation:

The frame adds 2 inches on each side of the window, so the width becomes 29 in. and the length becomes 36 in.

Area = width × length

So the total area of the window and the frame is:

A = 29 × 36 = 1044 in²

You want to find the value of x for which the area under the curve to the left of x is 0.6. One way to do that is to create the cumulative distribution function (CDF) for the given PDF, then see where it is equal to 0.6.

Doing that, we find a = 5.
