<h2>3)</h2>

\frac{y}{x}  =  \frac{4}{ - 3}  =  \frac{8}{ - 6}  =  \frac{12}{ - 9}  \\ this \: relation \: holds \: so \: y \: varies \\ directly \: with \: x

\frac{ 4}{3} m =  \frac{8}{ - 6}  \\ m =  \frac{ \frac{ - 8}{6} }{ \frac{3}{ - 4} }  =  \frac{8 \times 4}{6 \times 3}  =  \frac{32}{18}  = 2 \\ multipling \: by \: 2

<h2>2)</h2>

\frac{y}{x}  =  \frac{ - 40}{ - 0.5}  =  \frac{8}{2.5}  =  \frac{5}{4}  \\  \frac{y}{x}  = 80 = 3.2 = 1.25 \\ this \: is \: untrue \: so \: y \: is \: not \\ varying \: directly \: with \: x

no \: constant \: of \: variation

<h2>4)</h2><h2>\frac{y}{x}  =  \frac{21}{3}  =  \frac{31.5}{4.5}  =  \frac{38.5}{5.5 \\  }  \\  \frac{y}{x}  = 7 = 7 = 7 \\ y \: varies \: directl y\: with \: x \\ consant \: of \: var =  \frac{y}{x}  = 7</h2><h2>5)</h2>

\frac{y}{x}  =  \frac{30}{6}  =  \frac{35}{7}  =  \frac{96}{8}  \\  \frac{y}{x}  = 5 = 5 = 12 \\ y \: does \: not \: vary \: directly \: with \: x

A rectangle has length (3x-8) and width (2x-7) cm .Write down and simplify an expression for the perimeter of the rectangle. So
Verizon [17]

Answer:

The perimeter of the rectangle is equal to (10x-30)\ cm

Step-by-step explanation:

Let

L-----> the length of the rectangle

W ----> the width of the rectangle

we know that

The perimeter of rectangle is equal to

P=2(L+W)

we have

L=(3x-8)\ cm\\W=(2x-7)\ cm

substitute

P=2((3x-8)+(2x-7))

P=2(5x-15)

P=(10x-30)\ cm
