The expression that's always true is that D. a+c > b+d.
<h3>How to illustrate the information?</h3>
From the information given, it should be noted that we are told that a is less than b and c is less than d.
We are also informed that all the variables that are given are less than 0. Let's say a = -1, b = -2, c = -3 and d = -4.
Therefore, the expression that's always true is that. a+c > b+d. This will be:
= (-1 - 2) > (-3 - 4)
= -3 > -7
Based on the information given, the expression that is true is a+c > b+d.
Therefore, the correct option will be D.

Answer:
cant see the picture sorry
Step-by-step explanation:
Answer:
B. 1690.5 million VND
Step-by-step explanation:
Half of the perimeter of a rectangular piece of land is equal to 21 m
The full perimeter of the Land = 2 × 21m
= 42 m
Step 1
Find the Length and Width of the rectangle
Perimeter of a rectangle = 2L + 2W
Length is twice its width.
L = 2W
Hence:
42 = 2(2W ) + 2W
42 = 4W + 2W
42 = 6W
W = 42/6
W = Width = 7m
L = Length = 2W
L = 2 × 7
L = 14m
Step 2
Find the Area of the Land
Area of the rectangle = Length × Width
= 14m × 7m
= 98m²
Step 3
Given that 1 m² of the piece of land
costs 17.25 million VND. If someone wants to buy it, he or she has to
pay:
1m² = 17.25 million VND
98m² = x
Cross Multiply
1 m² × x = 98m² × 17.25 million VND
x = 1690.5 million VND
Option B is the correct answer
B quotient means divide so it is x/3 then 8 less means to subtract
