The answer is .9 bc you have to add the negative numbers, which is 1.6 then subtract the result to the other number, 2.5
(x-4)^2=36
take square roots,
± (x-4) =6
=>
x-4=6 => x=10
-(x-4)=6 => x-4 = -6 => x=-2
Answer:
Equilateral triangle (Green)
60° rhombus (2 triangles) (Blue) that can be matched with two of the green triangles
30° Narrow rhombus (Beige) with the same side-length as the green triangle
Trapezoid (half hexagon or 3 triangles) (Red) that can be matched with three of the green triangles
Regular Hexagon (6 triangles) (Yellow) that can be matched with six of the green triangles
Square (Orange) with the same side-length as the green triangle
All the angles are multiples of 30° (1/12 of a circle): 30° (1×), 60° (2×), 90° (3×), 120° (4×), and 150° (5×).
we are given
The water level in Ricky lake changes at an average of -7/48 inch for 1 year
It means that
In 1 year , the water level changes at 
and we have to find the water level change after 5 years
so, we can multiply both sides by 5
In 5*1 year , the water level changes at 
In 5 years , the water level changes at 
Hence,
the water level change after 5 years is
