Answer:

Area = 138in^2

Step-by-step explanation:

Given

L = 9; W =3; H =3\frac{1}{2}

Required

The surface area

This is calculated as:

Area = 2(LW + LH + WH)

So:

Area = 2(9*3 + 9*3\frac{1}{2} + 3*3\frac{1}{2})

Area = 2(27 + 31\frac{1}{2} + 10\frac{1}{2})

Area = 2*69

Area = 138in^2

Answer:

  • \frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}

Step-by-step explanation:

<u>Given</u>

  • \frac{5}{3}xz^a*bx^cy^dz^2 = 15x^7z^{10}

<u>Simplify</u>

  • \frac{5}{3}b*x^{1+c}z^{a+2}y^d = 15x^7z^{10}y^0

Compare left and right sides and

<u>Find b:</u>

  • <u />\frac{5}{3} b = 15 ⇒ b = 15*3/5 = 9

<u>Find c:</u>

  • 1 + c = 7 ⇒ c = 7 - 1 = 6

<u>Find a:</u>

  • a + 2 = 10 ⇒ a = 10 - 2 = 8

<u>Find d:</u>

  • d = 0

<u>Solution is:</u>

  • \frac{5}{3}xz^8*9x^6y^0z^2 = 15x^7z^{10}

The length of a rectangle is twice it’s width.The length is 12cm.Work out the area of the rectangle
aliina [53]

Answer:


Step-by-step explanation:

As with all word problems we first have to convert it to an equation or equations.

L = length of the Rectangle and W = its width

So L = 2 * W

A = area of the rectangle which is 128 cm^2

So    A = L * W = 128 cm^2

substitute 2W for L from the 1st equation to give    A = 2 * W * W = 2 * W^2 = 128 cm^2

Thus    W^2 = 64 cm^2

finally  W = 8 cm  and therefore  L = 2 * W = 16 cm

The perimeter P = 2 * (L+W) = 2* (8cm + 16cm) = 2 * 24cm = 48 cm
