-9/1*4/3=-36/3
-36/3 is known as -12. The answer is -12.
26,300 = 1/2x + 3200......with x being last years population
The resulting expression for the variable v is u - e - g
<h3>Subject of formulas</h3>
Subject of formula is a way of representing a variable in terms of another variable.
Given the expression below;
u=e+g-v
We are to make v the subject of the formula
Subtract e + g from both sides
u- (e + g)=e+g-v - (e+g)
u - (e+g) =v
Expand the left hand side of the expression
u - e - g = v
Swap
v = u - e - g
Hence the resulting expression for the variable v is u - e - g

The area of the shaded region is 46,77
Step-by-step explanation:
To determine the area of the shaded hexagon, we must first calculate te area of the whole shaded hexagon and minus that by the white little hexagon.
The formula to calculate the area of a hexagon is (3√3 s2)/ 2
(where s = one side of the hexagon)
if one side a the little white hexagon equals 6 ft;
3√3 6ft.2/2 = 18√3/2 = 9√3
now for the bigger hexagon where one side is 12 ft;
3√3 12 ft.2/2 = 72√3/2 = 36√3
now the area of the bigger one minus the area of the smaller one;
36√3 - 9√3 = 46,77
Sin 20 is the answer
Using the trigonometry rule
Sin cos tan
Sin x = opposite side (a) / hypotenuse side (c)
A/c = sin x
x= 20 ( angle formed by side c and b )
