Answer:

Area of a square = Length × Length

Area of a triangle = 1/2 base × height

Area of a rectangle = Length × breadth

Area of a parallelogram = base × height

Area of a trapezoid = 1/2 × sum of parallel sides × height

Area of circle = π × square of the radius

Area of ellipse = π × product of major and minor radii

Area of equilateral triangle = 1/2 base × height

Step-by-step explanation:

The area of a square is calculated by multiplying the length by itself.

The area of a triangle is calculated by multiplying half the base of the triangle by its height

The area of a rectangle is found by multiplying the length of the rectangle by its breadth

The area of a parallelogram is calculated by multiplying the base of the parallelogram by its height

The area of a trapezoid is found by multiplying half the sum of the two parallel sides by its height

The area of a circle is calculated by multiplying pi by the square of the radius of the circle

The area of an ellipse is found by multiplying pi by the product of the major and minor radii of the ellipse

The area of an equilateral triangle is calculated by multiplying half the base of the triangle by its height. The height is calculated using Pythagoras theorem

Solve: 1 5 x = -10 A) -50 B) -20 C) -2 D) 2
Inessa [10]

Answer:

In order to find x, you will have to use the operation of equality to isolate the x.


15x=-10

<em>Now, use the division property of equality and divide by 15 on both sides. This will cancel out the 15 on the left side of the equation and isolate the x completely.</em>

-10/15=\frac{-2}{3}

<em>Thus, this is your answer:</em>

\boxed{x=-\frac{2}{3} }

Solve for r.<br> –5 ≥ 5 (r+5)
aleksandr82 [10.1K]

Answer:

-6 ≥ r

Step-by-step explanation:

–5 ≥ 5 (r+5)

Divide each side by 5

–5/5 ≥ 5/5 (r+5)

–1 ≥  (r+5)

Subtract 5 from each side

-1-5 ≥ r+5-5

-6 ≥ r

Identify the property used in the first five steps to solve the equation 2(x-5)-6x=-22
Alona [7]
To answer this question, you need to multiply the number inside the bracket first. Then you can move the number to the right side of the equal sign and keep the x on the left side of the equal sign. The step would be like this
2(x – 5) - 6x= -22(2x - 10) - 6x = -222x - 6x  = -22 +10-4x= -12x= -12/-4x=3
Hope this helps!!!
