Answer:
Area of rectangle, 
.
Step-by-step explanation:
We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.
The area of a rectangle is equal to the product of its length and breadth. It is given by :
Let us consider, L = (2x-4) units and B = (x+1) units
Plugging the side lengths in above formula:
So, the function that models the area of a rectangle is .
Answer:
the absolute value of an integer is equation to the opposite of the integer
Answer:
1,451.61 cm²
Step-by-step explanation:
A = LW
A = 38.1 x 38.1 (since a checkerboard has to be square)
A = 1,451.61
Answer:
c. (5, -2)
Step-by-step explanation:
as we can clearly see, the 4th vertex has to be on the positive side of x.
therefore, all answer options with negative x are out.
(2, -5) is almost at D (-1, 5). that cannot be right for a rectangle.
that leaves only c as right answer.
FYI - how to get this without predefined answer portions ?
the x- difference of B to A is 4 (from -5 to -1). the x-difference from D to C must be the same (4). 1 + 4 = 5.
so, x of D must be 5.
the y- difference of B to A is 3 (from 3 to 6). the y-difference from D to C must be the same (3). -5 + 3 = -2.
so, y of D must be -2.
Add 5 to both sides to get x alone and you will have your answer which is x= -3
