calculate the slopes of the lines using the gradient formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
(x₁, y₁ ) = A(- 4, - 1) and (x₂, y₂ ) = B(-1, 2 )
= 
= 
= 1
(x₁, y₁ ) = B(-1, 2) and (x₂, y₂ ) = (5, 1)
= 
= - 
(x₁, y₁) = C(5, 1 ) and (x₂, y₂ ) = D(1, - 3)
= 
= 
= 1
(x₁, y₁) = A(- 4, - 1) and (x₂, y₂) = D(1, - 3 )
= 
= - 
Quadrilateral ABCD is not a parallelogram since only one pair of opposite sides is parallel , that is AB and CD
I think so it all looks right good luck
Answer: C 900
Step-by-step explanation:
Given: Requirement of carpeting in an apartment = 36 square yards
Then, the number of square yards require of carpeting do 25 identical apartments is given by :-
Hence, 900 square yards require of carpeting do 25 identical apartments .
Answer:
31 and 24
Step-by-step explanation:
63 divided by two is 31.5 and then minus 7 is 24.5
Multiply everyone by 100 gets:
56, 58, 53, 65, 60
thus
53/100<14/56<29/50<3/5<13/20
