Answer:

${3x}^{2} + 24x - 6$

Step-by-step explanation:

To find the area of a rectangle you have to multiply the length by the width.

In your problem, the length and width are both equations, so you just have to multiply each part of the equation separately.

For example, if you were to put both equations with one over the other, you just have to multiply the aligned numbers.

The length is: x2 + 6x + 3

The width is: 3x2 + 4x - 2

and if you multiply the aligned numbers together, you get

3x2 + 24x - 6. Because:

x2 × 3x2 = 3x2,

6x × 4x = 24x,

and 3 × -2 = -6

The sum of the ages of Mr Lin and his son Ethan is 38 years. In three years' time, Mr Lin will be three times as old as his son.

Sati [7]

Answer:

Mr.Lin's present age is 30 years now. His son is 8 years old now.

Step-by-step explanation:

Let L = Mr.Lin's present age,

S = his son's present age.

First equation is

L + S = 38. (1)

The second equation is

L + 3 = 3*(S+3) (2) ("In three years' time, Mr.Lin will be three times as old as his son.")

From (1), express S = 38-L and substitute it into (2). You will get

L + 3 = 3*((38-L)+3), or

L + 3 = 114 - 3L + 9,

4L = 114 + 9 - 3,

4L = 120,

L = 30.

(5) Rewrite the integral Z 1 0 Z x 0 Z √ 1−x2 0 z dz dy dx in the order dy dx dz, and evaluate it. Hint: You will need a reasona

Natalija [7]

Looks like the integral is supposed to read

$\displaystyle\int_0^1\int_0^x\int_0^{\sqrt{1-x^2}}z\,\mathrm dz\,\mathrm dy\,\mathrm dx$

The same integral in the required order is

$\displaystyle\int_0^1\int_0^{\sqrt{1-z^2}}\int_0^xz\,\mathrm dy\,\mathrm dx\,\mathrm dz$
