Shown is a regular pentagon, find y.
timama [110]

Answer:

54 degrees

Step-by-step explanation:

Every side of a regular pentagon is same.

So we have an  isosceles triangle. The  correspond angle of y, must equal to y (degree) too.

Also, every inner angle of a regular pentagon is 360/5=72. So we can calculate angle y, by the equation y+y+72=180.

y=54

At the rate that Darla is reading, how long will it take her to read 540 pages?
True [87]

Answer:

B: 15 hours

Step-by-step explanation:

Since Dara spends 2 hours reading 72 pages, we can conclude that she spends 1 hour reading 36 pages.

Since we are finding how long it would take for her to read 540 pages, we would divide 540 by 36, which is 15.

If the area of a rectangle is x^2+7x+12, what is the expression for the perimeter?
Cerrena [4.2K]

Length = 13 = (x + 3)

Width = 14 = (x + 4)

x2 + 7x + 12 = area of the rectangle

can be factored into

(x + 3)(x + 4)

Let L = one of the factors (x + 3)

Let W = the other factor (x + 4)

If x = 10 then

(10 + 3) = 13 = L

(10 + 4) = 14 = W

Checking this can be checked a couple of ways

Plug x = 10 into the original equation

x2 + 7x + 12

102 + 7(10) 12 = 100 + 70 + 12 = 182 = Area

Multiplty the factors

L x W = 13 x 14 = 182 = Area

I hope you find this useful if you have any questions please send me a message.
