Answer:

[tex]40.32cm^{2}[/tex]

Step-by-step explanation

4*1.2=4.8

7*1.2=8.4

8.4*4.8=40.32

A rectangle is a two-dimensional shape where the length and width are different.

The length and width of the larger rectangle are 4.8 cm and 8.4 cm.

The area of the larger rectangle is 40.32 cm².

A rectangle is a two-dimensional shape where the length and width are different.

The area of a rectangle is given as:

Area = Length x width

We have,

Two similar rectangles:

Smaller rectangles:

Length = 4 cm

Width = 7 cm

Larger rectangles:

Length = 4.8 cm

We need to find the width of the larger rectangle.

Since the two rectangles are similar.

4 cm = 4.8 cm

Multiply 7/4 on both sides.

7/4 x 4cm = 7/4 x 4.8 cm

7 cm = 8.4 cm

Now,

Larger rectangle:

Length = 4.8 cm

Width = 8.4 cm

Now,

The area of the larger rectangle:

Area = Length x width

Area = 4.8 x 8.4

Area = 40.32 cm²

Thus,

The area of the larger rectangle is 40.32 cm².

Answer:

remainder = 0

Step-by-step explanation:

Using the remainder theorem

If f(x) is divided by (x - h) then the remainder is f(h)

Here f(x) = x³ - x² - 17x - 15 and h = 5 , thus

f(5) = 5³ - 5² - 17(5) - 15 = 125 - 25 - 85 - 15 = 0 ← remainder

Since remainder is zero then (x - 5) is a factor of f(x)

[tex] \sqrt{x + 9} = x - 3[/tex]

Sides gets power 2

[tex] ({ \sqrt{x + 9} })^{2} = ( {x - 3})^{2} [/tex]

[tex] |x + 9| = {x}^{2} - 6x + 9 [/tex]

_________________________________

[tex]x + 9 = {x}^{2} - 6x + 9[/tex]

Subtract sides 9

[tex]x + 9 - 9 = {x}^{2} - 6x + 9 - 9[/tex]

[tex]x = {x}^{2} - 6x[/tex]

Subtract sides x

[tex]x - x = {x}^{2} - 6x - x[/tex]

[tex] {x}^{2} - 7x = 0[/tex]

[tex]x(x - 7) = 0[/tex]

[tex]x = 0[/tex]

OR

[tex]x - 7 = 0[/tex]

[tex] x = 7[/tex]

_________________________________

[tex]x + 9 = - ( {x}^{2} - 6x + 9)[/tex]

[tex]x + 9 = - {x}^{2} + 6x - 9[/tex]

Subtract sides 9

[tex]x + 9 - 9 = - {x}^{2} + 6x - 9 - 9 \\ [/tex]

[tex]x = - {x}^{2} + 6x - 18 [/tex]

Subtract sides x

[tex]x - x = - {x}^{2} + 6x - 18 - x [/tex]

[tex] - {x}^{2} + 5x - 18 = 0[/tex]

Multiply sides by -1

[tex] {x}^{2} - 5x + 18 = 0 [/tex]
