This should help-
Triangle Total angle measures = 180
Right angle= 90
Line = 180
The easiest way is if it doesn't need to be simplified. Multiply -2.105 by

. You get the fraction

. While this is technically the answer, you can simplify this down to

. Because 421 is a prime number, this can not be simplified any further. Therefore, the solution is

.

.
Lateral area is the area of the faces, while surface area is the area of the faces and and bases.
Answer:
w = -19
Step-by-step explanation:
-6w + 4(w +3) = 26
-6w + 4w + 12 = 26
simplify
-2w + 12 = 26
now get the variable and the numbers on different sides
-2w + 12 - 12 = -2w
26 + 12 = 38
-2w = 38
now divide each side by -2
-2w / -2 = w
38 / -2 = -19
w = -19
First of all it is always a good idea to graph a question like this one. Here are the three graphs
y = x^4 - x^2 Color: Red This is the base graph
y = x^4 - x^2 - 4 Color Blue This has - 4 added to it.
y = x^4 - x^2 + 4 Color Green This has 4 added to the base graph
Which one is correct? The red and blue one are not. The graph you want is plotted upward from the base graph. The base graph (red nothing added to it) is not right because it has points on the x axis. The graph you want does not.
The same is true of the blue graph. It cuts the x axis. That only leaves the green one.
