a walkway surrounds a rectangular garden. the width of the garden is 8 feet, and the length is 6 feet. the width x of the walkway around the garden is the same on every side. write an expression that represents the total area of the garden and walkway.

  =4x^2 +28x+48

Step-by-step explanation:

Width of the garden is 8

There is walkway on each side of width so add x on each side

With the walkway is x+8+x = 2x+8

Length of the garden is 6

There is walkway on each side of length so add x on each side

With the walkway is x+6+x = 2x+6

The area of the garden is

A = lw

A = 8*6 = 48

The area of the walkway and garden is

A = lw

   = (2x+8) (2x+6)

   FOIL   (first outer inner last)

  = 4x^2 + 12x + 16x +48

  =4x^2 +28x+48

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
