Step-by-step explanation:
In order to calculate the volume of a triangular prism you need 2 things:
The triangles area and the prism's height.
Any prism's volume can be calculated by multiplying its base area with its height.
The Area of a triangle can be calculated in different ways.
The most used and "normal" way is:
(width * height) / 2
Another way is by using herons formula, which looks like this:
a, b, c = different sides of the triangle (length)
s = (a + b + c) / 2
a = 
When you have the prism's base area (
) you just have to multiply:
(V = volume)

Answer:
A 29 is the answer to the problem
Answer:
8/21
Step-by-step explanation:
The total job is 1
Mike has done 1/3 and Dena has done 2/7 of the job We still need to do x of the job to complete it
1/3 + 2/7+ x = 1
We need to get a common denominator 3*7 = 21
Multiply each side by 21
21(1/3 + 2/7+ x) = 1*21
21(1/3) + 21*(2/7)+ 21x = 21
7+ 3*2 +21x =21
7+6+21x = 21
13+21x = 21
Subtract 13 from each side
13-13+21x=21-13
21x = 8
Divide each side by 21
21x/21 = 8/21
x = 8/21
We need to complete 8/21 of the job
Trust me: You must know how to do this basic factoring yourself.
x^2 -5x - 6 factors into (x-6)(x+1). Note how I got that: -6 is the product of 1 and -6, and -6 + 1 = -5.
You could also factor this by grouping:
x^2 -5x - 6 = x(x-6) + 1(x-6). Note how the middle terms combine to produce -5x and how (x-6) is a factor common to both terms; this leaves (x+1). So the factors are (x-6)(x+1).
