It would be -145 if its below sea level.

348in²

Step-by-step explanation:</h2>
6*8 = 48. This is the surface area of the largest rectangle.
6*9 = 54. This is the surface area of the top rectangle.
8*9 = 72. This is the surface area of the smallest rectangle.
The total is 72+54+48, so 174.
Because there are two of each rectangle, you times this number by 2.
174 * 2 = 348in².
7.81
Round the 2 to get 7.81
I assume we are solving for x?
You need to isolate x on one side of the equation.
subtract 4x from both sides. This leaves -2x+3=-3. Because we need to isolate x we subtract 3 from both sides, leaving -2x=-6. Again we isolate x, divide both sides by -2. x=3
2x+3=4x-3
-2x+3= -3
-2x= -6
x=3
Answer:
Step-by-step explanation:
For two angles x and y to be supplementary, the sum of the angles must be 180°
x+y = 180
x = 180-y... 1
If the measure of the angle is five times greater than its supplement this is expressed as:
x = 5y…. 2
Substitute equation 2 into 1
5y = 180-y
5y+y = 180
6y = 180
y = 30°
Hence the measure of the supplement is x = 5y
x = 5(30)
x = 150°
