The length of a rectangle is 3 inches longer than it is wide. if the 46 inches what are the dimensions of the rectangle

Hello from MrBillDoesMath!

10 and 13

Discussion:

Let "w" be the width of the rectangle.  Then

Perimeter= 46

2w + 2l = 46

2w+ 2(w+3) = 46                               => as l = w+ 3

2w + 2w + 2*3    = 46                       =>

2w + 2w + 6 = 46                             => 2 + 6 = 8

6 + 4w = 46                                      => subtract 6 from both sides

4w = 46 - 6  = 40                             => divide both sides by 2

w = 40/4 = 10

As l = w + 3, l = 10+ 3 = 13

Thank you,

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
