Match the formula with the polygon.
kherson [118]

Step-by-step explanation:

Lets sort out the areas of the polygons to match the areas with the corresponding polygons.

1. Triangle

The formula of the area of the triangle will be:

A\:=\:\frac{1}{2} \:\:b\:h

where b is the base and h is the height of the given triangle

2. rhombus

The formula of the area of the rhombus will be:

A\:=\:\frac{pq}{2}

where p and q being the diagonals

3. Parallelogram

The formula of the area of the parallelogram will be:

A = bh

where b is the base and h is the height

4. square

The formula of the area of the square will be:

A\:=\:s^2

where s being the length if any side, as all sides are equal in square

5. trapezoid

The formula of the area of the trapezoid will be:

A\:=\:\frac{1}{2}\:h\left(b1\:+\:b2\right)

where h is the height and b1 and b2 being the bases.

6. regular polygon

The formula of the area of the regular polygon will be:

A\:=\:\frac{\left(ap\right)}{2}

where a is the apothem and p is the perimeter.

7. equilateral triangle

The formula of the area of an equilateral will be:

A\:=\:1/4\:s^2\:sqrt\left(3\right)

where s is the length of one side of the triangle

Keywords: area, Triangle, square, parallelogram, rectangle, trapezoid, regular polygon, equilateral triangle

Hello, I'm trying to solve 6x + y = 4, x - 4y = 19. I have found the y but I cant seem to find the x. Plz help and we cant use d
gizmo_the_mogwai [7]

Answer:

x=\frac{7}{5}

y=-\frac{22}{5}

Step-by-step explanation:

Given:

The given expressions are.

6x+y=4

x-4y=19

We need to find x and y values.

Solution:

Equation 1⇒ 6x+y=4

Equation 2⇒ x-4y=19

First solve the equation 1 for y.

6x+y=4

y = 4-6x --------(3)

Substitute y = 4-6x in equation 2.

x-4(4-6x)=19

Simplify.

x-(4\times 4 - 4\times 6x)=19

x-(16-24x)=19

x-16+24x=19

Add 16 both side of the equation.

25x-16+16=19+16

25x=35

x=\frac{35}{25}

Divide Numerator and denominator by 5.

x=\frac{7}{5}

Substitute x value in equation 3 and simplify.

y=4-6(\frac{7}{5})

y=4-\frac{6\times 7}{5}

y=4-\frac{42}{5}

y=\frac{5\times 4-42}{5}

y=\frac{20-42}{5}

y=-\frac{22}{5}.

Therefore, the value of x=\frac{7}{5} and y=-\frac{22}{5}.
