A rectangular shaped garden has an area of 80 square feet. The length is 5 less than twice the width. What are the dimensions of
Gnom [1K]

Answer:

Width=28 1/3 Length=51 2/3

Step-by-step explanation:

1. Create an equation

x+(2x-5)=80

2. Solve

x+(2x-5)=80

3x-5=80

3x-5+5=80+5

3x/3=85/3

x=28 1/3

So, if x=28 1/3

85/3x2=170/3

56 2/3-5

So, Length=51 2/3

Find the distance between the two points.
Ksenya-84 [330]

Hey there!

Distance formula:

d = \sqrt{(x_{2}-x_{1})+(y_{2}-y_{1}) }

Plug in variables:

d = \sqrt{(0-(-6))+(0-(-7))}

Simplify.

d = \sqrt{6+7}

d = \sqrt{13}

The distance between the two points is \sqrt{13}  units.

Hope this helps!

f(x) = 2x^2 - 5x

Let x=4

f(4) = 2 (4)^2 -5(4)

Exponents first

     = 2*16 -5*4

Multiply

     =32 -20

subtract

A área de um retângulo é igual a 44, sabendo que as suas medidas são iguais a 4 e (3x+2), calcule a medida do lado maior deste r
jekas [21]

Responda:

11

Explicação passo a passo:

Área do retângulo = comprimento * largura

Dado

Comprimento = 4

Largura = 3x + 2

Área = 44

Substitua na fórmula e obtenha x

44 = 4 (3x + 2)

44 = 12x + 8

12x = 44-8

12x = 36

x = 36/12

x = 3

Obtenha os lados mais longos

Lado mais longo = 3x + 2

Substitua x = 3

Lado mais comprido = 3 (3) + 2

Lado mais comprido = 11

Portanto, a medida do lado mais longo deste retângulo é 11
