The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.
Answer:
Answer is B
Step-by-step explanation:
If point D with coordinates (a,b) is reflected over the line y=x then the image point D' coordinates are (b,a) (see picture for details).
The middlepoint M of segment DD' lhas coordinates and lies on the line y=x (since its coordinates are equal), DD' is perpendicular to the line y=x and DM=D'M. All these remarks show that the point D' is the image point of D.
Answer:
x = 6
Step-by-step explanation:
The product of x and 3 is 3x
5 increased by this product is 5 + 3x, thus
5 + 3x = 23 ( subtract 5 from both sides )
3x = 18 ( divide both sides by 3 )
x = 6
