The perimeter of a rectangular fence is to be at least 144 feet and no more than 216 feet. If the length of the fence is to be three times the width, what is the range of values for the width of the fence? __ ft ≤ width ≤ __ ft

let width be x

then length= 3x

in first case

2(x+3x)= 144

8x=144

x=18

again

2(x+3x)= 216

8x= 216

x=27

the range for width is

18≤ width ≤27

Step-by-step explanation:

4th option is correct xy=-10

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.
