Solve this problem out

Virty [35]

Option C

When $(2x - 3)^2$ is subtracted from $5x^2$ then the result is $x^2 + 12x - 9$

<h3><u>Solution:</u></h3>

Given that $(2x - 3)^2$ is subtracted from $5x^2$

We have to find the result

Subtraction is a mathematical operation that tells us the difference between two numbers.

When "a" is subtracted from "b", we write in mathematical expression as "b - a"

So $(2x - 3)^2$ is subtracted from $5x^2$ is written mathematically as:

$\rightarrow 5x^2 - (2x - 3)^2$

<em><u>Expanding the above expression using algebraic identity:</u></em>

$(a-b)^2 = a^2 - 2ab + b^2$

$\rightarrow 5x^2 - ((2x)^2 -2(2x)(3) + (3)^2)\\\\\rightarrow 5x^2 - (4x^2 - 12x + 9)$

Multiplying the nnegative sign with terms inside bracket

<em><u>There are two simple rules to remember: </u></em>

When you multiply a negative number by a positive number then the product is always negative.

When you multiply two negative numbers or two positive numbers then the product is always positive.

$\rightarrow 5x^2 - (4x^2 - 12x + 9)\\\\\rightarrow 5x^2 - 4x^2 + 12x -9\\\\\rightarrow x^2 + 12x - 9$

Hence the result is: $x^2 + 12x - 9$

The surface area of each face of a cube is (x

Assoli18 [71]

Answer:

length of each edge = (x + 3)

Step-by-step explanation:

The surface area of each face of the cube = ( $x^{2}$ + 6x + 9) $m^{2}$ . But the surface of a cube has the shape of a square. So that,

Area of a square = length x length

= $l^{2}$

By factorizing the area,

$x^{2}$ + 6x + 9 = $x^{2}$ + 3x + 3x + 9

= ( $x^{2}$ + 3x) (3x + 9)

= x(x +3) + 3(x + 3)

= (x + 3)(x + 3)

= $(x + 3)^{2}$

$x^{2}$ + 6x + 9 = $(x + 3)^{2}$

Thus,

$(x + 3)^{2}$ = $l^{2}$

find the square root of both sides

l = (x + 3)

length of each edge = (x + 3)

Please please help me dayson is covering a package in the shape of a rectangular prism with wrapping paper. the package is 50 ce

olga2289 [7]

The package has a surface area of 4520cm². The area of the package is less than the area of the wrapping paper. So, dayson can cover the package with the wrapping paper.

According to the question,

The first step is to determine the surface area of the package.

Total surface area of a cuboid = 2 (l w + w h + l h)

where:

• l = length

• w = width

• h = height

2[(50 x 20) + (50 x 18) + (20 x 18)] = 4520cm²

The second step is to convert 1 square meter to cm

1m² = 100 cm²

100 x 100 = 10,000
