Answer:
Step-by-step explanation:
1. Parallelogram and rectangle
Sides: The opposite sides of both parallelogram and the rectangle are parallel and are equal.
Angles: Opposite angles of both parallelogram and rectangle are equal and adjacent angles of both parallelogram and rectangle are supplementary.
Relationship: Not all parallelograms are rectangle but all rectangles can be parallelograms.
2. Parallelogram and square:
Sides: Opposite sides of both the square and the parallelogram are parallel, but all sides are same in square but opposite sides are equal in parallelogram.
Angles: Opposite angles of both parallelogram and square are equal and adjacent angles of both parallelogram and square are supplementary.
Relationship: All squares are parallelograms but not all parallelograms are squares.
Answer:
i believe it is 0.2143
Step-by-step explanation:
To solve this equation, you know you have two numbers which you can represent with x and y.
Larger number = y Twice the smaller number subtracted from the larger
Smaller number = x is equal to 13:
y - 2x = 13 Solve for y: y = 2x + 13 Then substitute your value for y into the equation they gave you at the beginning:
(2x + 13) + x = 52 Solve the equation by simplifying:
3x = 52 - 13 3x = 39 x = 13 Then substitute your value for x (13) into the equation we made to solve for y:
y - 2(13) = 13 y - 26 = 13 y = 39
So your answer is, "The two numbers are 13 and 39."
Answer: I believe the answer to that question is no
Step-by-step explanation: So you see, when there are not symbols that represent addition or subtraction, or any other operation, it's not considered a question.
Answer:
-3, 9
Step-by-step explanation:
x^2 -6x - 27=
= x^2 - 9x + 3x - 27
= x(x - 9) + 3(x - 9)
= (x + 3)(x - 9)
x = -3, x = 9
