Answer:
The surface area of the triangular prism is
.
Step-by-step explanation:
The surface area of any prism is the total area of all its sides and faces. A triangular prism has three rectangular sides and two triangular faces.
An equilateral triangle is a triangle with all three sides of equal length.
To find the surface area, the area of each face is calculated and then add these areas together.
The formula
is used to find the area of the triangular faces, where A = area, b = base, and h = height.
The formula
is used to find the area of the three rectangular side faces, where A = area, l = length, and w = width.
The surface area of the triangular faces is:

The surface area of the three rectangular side faces is:

The surface area of the triangular prism is
.
Answer:
Between 19 and 55, inclusive
Step-by-step explanation:
70 < Average < 79 (inclusive)
4×70 < sum < 4×79 (inclusive)
280 < sum < 316
280 < 92 + 84 + 85 + X < 316
280 < 261 + X < 316
19 < x < 55
Fourth score can be between 19 and 55, inclusive

Answer:
-1y+1x-2
Step-by-step explanation:
if you are combining like terms this is how you do it at all of the same variables together to simplify the expression
Answer:
Step-by-step explanation:
n is perpendicular. - 1/(2/5) = - 5/2. n is the negative reciprocal of the given line.
m is neither.
p is parallel to the given line. For example y = 2/5x
and y = 2/5 x + 9 are parallel to each other.
