Answer:

D

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplifying each radical

[tex]\sqrt{27}[/tex]

= [tex]\sqrt{9(3)}[/tex] = [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex] = 3[tex]\sqrt{3}[/tex]

[tex]\sqrt{12}[/tex]

= [tex]\sqrt{4(3)}[/tex] = [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex]

[tex]\sqrt{48}[/tex]

= [tex]\sqrt{16(3)}[/tex] = [tex]\sqrt{16}[/tex] × [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex]

Then

3[tex]\sqrt{3}[/tex] - 2[tex]\sqrt{3}[/tex] + 4[tex]\sqrt{3}[/tex]

= 5[tex]\sqrt{3}[/tex] → D

Answer:

The area of the trapezium for the given figure is 35 cm².

A trapezium is a quadrilateral with four sides where two sides are parallel to each other.

We have,

The area of the trapezium.

= 1/2 x (sum of the parallel sides) x height

Now,

Parallel sides = 6cm and 8cm

Height = 5 cm

Now,

Area.

= 1/2 x (6 + 8) x 5

= 1/2 x 14 x 5

= 35 cm²

Thus,

The area of the trapezium is 35 cm².

Answer:

x=3

Step-by-step explanation:

4x+5=17

    -5=-5

4x=12

divide both sides by 4

x=3

The solution of the equation 4x + 5 = 17 gives x equals to 3.

Given Equation:

4x + 5 = 17

Now, subtract 5 from both side of the equation is

4x + 5 - 5 = 17 - 5

Then, simplifying the expression

4x = 12

Now, divide both side of the equation by 4 as

4x/ 4= 12/4

x = 3

Therefore, the value of x is 3.

Answer:

C'(4, 4)

Step-by-step explanation:

Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, translation and dilation.

Dilation is the enlargement or reduction in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new point would be at A'(kx, ky).

Given that quadrilateral ABCD is dilated by a scale factor of 1/2 to form quadrilateral A'B'C'D'.

The vertices of quadrilateral ABCD is given by A(2, 2), B(4, 8), C(8, 8) and D(6, 4).

If quadrilateral ABCD is dilated by 1/2 to form quadrilateral A'B'C'D, the vertices of quadrilateral A'B'C'D would be A'(1, 1), B'(2, 4), C'(4, 4) and D'(3, 2).

The value of the inequality is x ≤ 20/3

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

3x + 10 ≤ 30   be equation (1)

On simplifying , we get

Subtracting 10 on both sides , we get

3x ≤ ( 30 - 10 )

3x ≤ 20

Divide by 3 on both sides , we get

x ≤ 20/3

x ≤ 6.333

Therefore , the value of x is less than or equal to ( 20/3 )

Hence , the inequality is x ≤ 20/3
