Answer:  The answer is AB = CD.

Step-by-step explanation: We are given a quadrilateral ABCD with AB ║ CD.

We know that a quadrilateral is said to be a parallelogram if any one of the following conditions is satisfied:

(i)  If both pairs of opposite angles of a quadrilateral are equal, then it is a parallelogram.

(ii) If one pair of opposite sides of a quadrilateral is both equal and parallel, then it is a parallelogram.

(iii) If the diagonals of a quadrilateral bisect each other, then it is a parallelogram.

We are given that AB is parallel to CD, so by the condition (ii), if we get the additional information that AB = CD, then ABCD will be a parallelogram.

Thus, the answer is AB = CD.

A square purple rug has a orange square in the center. The side length of the orange square is x inches. The width of the purple
Liono4ka [1.6K]

Answer:

578 + 48 square inches

Step-by-step explanation:

The computation of the area of the purple band is as follows:

Area of the green square = side^2 = x^ square inches

And, the area of the orange square = side^2

The side would be = = 12 + 12 +x  = 24 + x

And, now the area would be = (x + 24)^2

Now the area of the orange band is

= Area of the orange square  area of the green square

= (x + 24)^2 - x^2

= x^2 + 24^2 + 48  - x^2

= 578 + 48 square inches

Which constants could each equation be multiplied by to eliminate the x-variable using addition in this system of equations? 2x+
Elden [556K]

Answer:

The first equation can be multiplied by 3 and the second equation by 2.

Step-by-step explanation:

Given

2x+3y=25

-3x + y=22

Required

How to eliminate x

To eliminate x using addition, we have to do the following;

1. Take the coefficient of x in equation 1; Coefficient = 2

2. Take the coefficient of x in equation 2; Coefficient = -3

3. Multiply equation 1 by 3

3(2x + 3y = 25)

6x +9y = 75

4. Multiply equation 2 by 2

2(-3x + y = 22)

-6x + 2y = 44

5. Add both resulting equations

6x +9y = 75  +  -6x + 2y = 44

6x - 6x + 9y + 2y = 75 + 44

11y = 75 + 44

Notice that x has been eliminated;
