The perimeter of a rectangle is 52 cm. If its width is 2 cm more than one-third of its length, find the dimensions of rectangle.
Jobisdone [24]

Answer:

(B) 18 cm x 8 cm

Step-by-step explanation:

let the length be x,

then the width is \frac{1}{3}x + 2

2( \frac{1}{3}x + 2 + x ) = 52

\frac{1}{3}x + 2 + x  = 26

\frac{4}{3} x = 24

x = (24*3)/4

x = 18

then the length is 18 cm

and width is (1/3)*18 + 2 = 8

Therefore the dimensions are length:width = 18 cm : 8 cm

What is the distance between ( 8 , − 3 ) (8,−3)left parenthesis, 8, comma, minus, 3, right parenthesis and ( 4 , − 7 ) (4,−7)lef
Elena L [17]

Given Information:

Point 1 =  (8, −3)

Point 2 =  (4, −7)

Required Information:

Distance between points = d = ?

Answer:

Distance between points = d = √32 = 5.657

Step-by-step explanation:

We are given two points,

(x₁, y₁) = (8, −3)

(x₂, y₂) = (4, −7)

We are asked to find the distance between these two points.

The distance is given by

d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 }

Substitute the given coordinates into above equation

d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 } \\\\d = \sqrt{(4 - 8)^2 +(-7 - (-3))^2 } \\\\d = \sqrt{(-4)^2 +(-7 +3)^2 } \\\\d = \sqrt{(-4)^2 +(-4)^2 } \\\\d = \sqrt{16 +16 } \\\\d = \sqrt{32} \\\\d = 5.657

Therefore, the distance between (8, −3) and (4, −7) is 5.657 units.

Im dumb as heck so plez halp​
spayn [35]
The answer is 4
The area is length X width
It is also a square meaning all sides are equal
So with this is mind we can ask the question what times what equals 16 and is the same number
This would be 4 since 4 times 4 is sixteen
