Answer:
A rectangle
Step-by-step explanation:
Plot it carefully on grid paper. You will see that opposite sides are congruent making it a parallelogram, but adjacent sides are not, so it is not a square or a rhombus. Also each two adjacent sides are perpendicular, so it makes it a rectangle.
Answer:
C) never
Step-by-step explanation:
It means the system of equations is true for all values of the variables that satisfy one of the equations. The other equation is identical, so any values that satisfy the first equation will also satisfy the second equation.
There will be an infinite number of solutions. There will never be no solution.

<u>Example</u>:
x + y = 4
-x -y +4 = 0
Adding the two equations gives ...
(x +y) +(-x -y +4) = (4) + (0)
4 = 4
The solutions to this system are all values of x and y such that x+y=4. There are an infinite number of such solutions.
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above: <span>twice the length of the shortest side plus the length of the longest side is 248 inches.
2. Therefore, keeping on mind the information above, you have:
x: the shortest side
x+6: the longest side
2x+(x+6)=248
3x+6=248
3x=242
x=242/3
x=80.66 (The shortest side)
x+6=80.66+6=86.66 (The longest side)
The answer is: 86.66

Answer:
it will be 7×9 = 63 cuz when you times 4×9 =36 or 5×9 =45
