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.

The answer is C 43-(16+11)
A shows 11 plus the sum of 43 minus 16
B shows the sum of 16 plus 11 minus 43
Answer:
x = 7
Step-by-step explanation:
3x/2 - 10 = 1/2
3x/2 - 20/2 = 1/2
3x - 20 = 1
3x = 21
x = 7

Area covered by the forest in the beginning = 1500km²
Decrease in area each year = 5.8% = 5.8/100 × 1500 = 87km²
Decrease in the area of the forest in <em>t</em> years = 87t
Area of forest now = y
y = 1500 - 87t
Answer:
Step-by-step explanation:
Midpoint of the diameter is the center.
<u>Use midpoint formula to determine the coordinates:</u>
- x = (2 - 4)/2 = -1
- y = (5 + 13)/2 = 9
<u>Find the radius using the midpoint and one of the endpoints and the distance formula:</u>
- r =
<u>Use the equation of the circle:</u>
- (x - (-1))² + (y - 9)² = 5²
- (x + 1)² + (y - 9)² = 25
Correct choice is 4
