The equivalent expression is negative eleven sixths times n minus one twelfth. Option C

Algebraic expressions are expressions that comprises of variables, terms, constants, coefficients and factors.

They are also made up of arithmetic operations such as division, multiplication, addition, subtraction, bracket, etc.

Equivalent expressions are expressions with the same solution but different arrangement of elements.

Given the expression

{ -3 1/3n + 1/6} + { 1 3/6n - 3/12 }

expand the bracket

-3 1/3n + 1/6 + 1 3/6n - 3/12

collect like terms

-10/3n + 1/6 + 9/6n - 3/12

-10/3n + 9/6n + 1/6 - 3/12

find the lowest common multiple

-20n + 9n/6 + 2 - 3 /12

-11n/6 - 1/12

Thus, the equivalent expression is negative eleven sixths times n minus one twelfth. Option C

The area of rectangle  is 1.42×2=2.84

Given,

The area of rectangle is 1.42×2=2.84

The length of rectangle is 1.38×.98=1.3524

A rectangle is a quadrilateral with equal angles and opposing sides that are equal and parallel. There are several rectangle items all around us. Each rectangle form is distinguished by two dimensions: length and breadth. The length of the rectangle is the longer side, while the width is the shorter side. We will study about the rectangle form and its features in this chapter.

The rectangle is a four-sided closed two-dimensional shape. A rectangle's opposite sides are equal and parallel to one other, and all of its angles are equal to 90°.

The value of 9-3-3-3=0 written as division problem is the value of 0.333

According to the Honor algebra:

The symbols for variables used in algebra, which may be found in Greek and Latin literature, can be used to date the creation of algebra to the height of Greek or Latin culture.

9-3-3-3=0 as written as division

⇒ 9÷3÷3÷3 =0

⇒ 9÷3 =3÷3

⇒ 3=1

⇒ x=1/3

⇒ x=0.333

so, the value of 9 divide by 3 and divided by 3 equals to 3 divvied by 3 is the value of 0.333.

When things are more realistic, algebra becomes much more intriguing. With a two-pan balance, some mystery bags, and a ton of jelly beans, solving linear equations is much more enjoyable.

Therefore, the 9-3-3-3=0 written as division is the value of 0.333.

The length of the sides are solved to be

Given data

perimeter of a right angled triangular park is 120m

area is 600m^2

Perimeter of triangle = b + h + √(b^2 + h^2)

Area of triangle = 0.5 * b * h = 0.5bh

120 = b + h + √(b^2 + h^2)   equation 1

600 = 0.5bh                          equation 2

form equation 2

bh = 1200

from  equation 1

120 - b - h = √(b^2 + h^2)  

( 120 - b - h )^2 = (b^2 + h^2)

( 120 - b - h ) * ( 120 - b - h ) = (b^2 + h^2)

14400 - 120b - 120h - 120b + b^2 + bh - 120h + bh + h^2 = (b^2 + h^2)

14400 - 240b - 240h  + b^2 + 2bh + h^2 = b^2 + h^2

14400 - 240b - 240h  + 2bh = 0

and bh = 1200

14400 - 240b - 240h  + 2 * 1200 = 0

14400 - 240b - 240h  + 2400 = 0

16800 - 240( b + h ) = 0

16800 = 240( b + h )

b + h = 70

b = 70 - h

and bh = 1200

h ( 70 - h ) = 1200

70h - h^2 = 1200

h^2 - 70h + 1200 = 0

h = 40 or 30

if h = 30

and bh = 1200

b = 1200/30

b = 40

the hypotenuse is solved from Pythagoras

hypotenuse =  √(b^2 + h^2)

Given that

The quadrilateral ABCD's vertices are located at A(-6,-1), B(-5,2), C(-1,5), and D. (0,-2).

According to the statement

We have to find that the whether the quadrilateral is a parallelogram or not.

So, For this purpose, we know that the

A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.

From the given information:

The coordinates of the vertices of quadrilateral ABCD are A(-6,-1), B(-5,2), C(-1.-5), and D(0.-2).

Then

To show that the diagonals are bisect each other, we have to find the midpoint of both diagonals and if the midpoint is same then they bisect each other.

So,

Midpoint of AC = Midpoint of BD

Midpoint of A(-6,-1),C(-1.-5)  = Midpoint of B(-5,2),D(0.-2)

( -6-1/2 , -1-5/2) = (-5+0/2 , 2-2/0)

( -7/2 , -6/2) = (-5/2 , 0/2)

And these midpoints are not same then they do not bisect each other and then it is not a parallelogram.

Answer:

y= -6/7x+8

Step-by-step explanation:

7x-6y=13

6y=7x-13

y=7/6x-13/6

a perpendicular line has the x-axis as the reciprocal and the opposite

so

y= -6/7x+b

and to find b you take the x-axis, in this case, it is 14, multiply 14 by the slope which is -6/7. 14x-6/7= -12

-12 plus what number is -4? it's 8! -12+8=-4 b=8

so you get y=-6/7x+8

Answer:

70

Step-by-step explanation:

We can actually solve this based on two “rules” that are present in triangles and lines.

The first rule is that the three angles inside a triangle will always add up to 180.

In this case, we have 2 out of 3 angles given like so: 52 + 58 + k = 180

Solve for k and that gives 70

Another rule that reinforces this is that a straight line will have an angle of 180 degrees. With the 180 that is given, we can solve for k again using: 110 + k = 180

Answer:

70°

Step-by-step explanation:

Total angles of a triangle = 180°

Then, 180° = 58° + 52° = k

➟ 180° = 58° + 52° = k

➟ 180° - 180° + k =180° - (58° + 52°)

➟ k = 180° - 110°

➟ k = 70°

The area of the composite figure whose vertices have the  (2,-2), (2,1), (4,2), (6,2), (4,-1) coordinates is 6 square units

We first need to plot all the given points A  (2,-2), B (2,1), C (4,2), D (6,2)and E (4,-1) which is coordinate geometry

After joining the Points which is a pentagon and it can be divided in two shapes one is triangle CDE and a quadrilateral ABCE

Using the distance formula

BC = [tex]\sqrt{(y2-y1)^{2}+(x2-x1)^{2} }[/tex] = [tex]\sqrt{(2-1)^{2} + (4-2^{2} }[/tex] = √5

Since BC = AE and BC ll AE , we can say ABCE is a parallelogram

area of a parallelogram = base × Altitude

                                      = 2 × 2= 4

Area of triangle CDE where CD is perpendicular and CE is the base

                        = 1/2 ( 2×2)

                        = 1/2 (4)

                         = 2 square units

So the area of ABCDE = Area of ABCE + area of CDE

                                     = 4 square units + 2 square units

                                      = 6 square units

Hence, the area of the composite figure whose vertices have the  (2,-2), (2,1), (4,2), (6,2), (4,-1)coordinates is 6 square units
