A(1, 1)
b (1, 3)
c (4, 3)
rectangle abcd has the coordinates shown.

find the coordinates of point d.
a) (5, 1)
b) (4, 2)
c) (3, 1)
d) (4, 1)

The coordinate of D is (4,1)

D is correct

Step-by-step explanation:

A (1, 1)  

B (1, 3)  

C (4, 3)

ABCD is a rectangle.

Let coordinate of D be (x,y)

As we know mid point of both diagonal is same.

In rectangle ABCD

Diagonals are AC and BD.

So, Mid point of AC =  Mid point of BD

Formula:

Hence, The coordinate of D is (4,1)

898.1666667

step-by-step explanation:

5389/6 = 898.1666667

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
