184 - 124 = 60
so it has grown by 60 in 18 months. That is 3 1/3 per month.
so Number of citizens depending on month is 124 + (1 1/3)n
or 124 + 4n/3:
At population 1000:-
124 + 4n/3 = 1000
4n/3 = 1000-124
n = (1000-124) * 3/4 = 657 months

Step-by-step explanation:
<u>Step 1: Define</u>
P = 2L + 2W
<u>Step 2: Solve for </u><em><u>L</u></em>
- Subtract 2W on both sides: P - 2W = 2L
- Divide 2 on both sides: (P - 2W)/2 = L
- Distribute division: P/2 - W = L
- Rewrite: L = P/2 - W
Pythagorean theorem:
a² + b² = c²
a is the long leg of the triangle
b is the short leg of the triangle
c is the hypotenuse
side lengths ; 3 inches, 4 inches, 5 inches of a right triangle.
a = 4 inches
b = 3 inches
c = 5 inches
4² + 3² = 5²
16 + 9 = 25
25 = 25
Answer:
21 unit square
Step-by-step explanation:
First you want to find the length and width of the rectangle using the distance formula:
d=√(x2-x1)²+(y2-y1)²
AB=√(6-3)²+ (-2 - -2)²
AB=√3² + 0
AB=√9
AB=3
BC=√(6-6)²+ (5 - -2)²
BC=√0 + 7²
BC=√49
BC=7
We can find the area by multiplying these two distances together:
A=(3)(7)
A=21 units square.
