Given:
The base of the prism is a right triangle with legs 1 m and 2 m.
The height of the prism is 17 m.
To find:
The volume of the given prism.
Solution:
The area of a triangle is:
So, the area of base of the prism is:
Now, the volume of the prism is:
Where, B is the base area and h is the height of the prism.
Substituting 
, we get
The volume of the prism is 17 cubic m. Therefore, the correct option is (d).
First, add all of the working hours.
1
+ 2
+ 1
Since the denominators are different, make them all the same.
1
+ 2
+ 1
Add everything together.
4
+ 1
= 5
Then, simplify.
5
or 5.5
Multiply the time by the salary.

So legnth is 7 more than 6 times width
l=7+6w
area=10 cm^2
lw=area
subsitute
7+6w for l
(7+6w)(w)=10
7w+6w^2=10
subtract 10 from both sides
6w^2+7w-10=0
factor
multiply 6 and -10
get -60
now find what 2 numbers multiply to get -60 and add to get 7
the answe ris -5 and 12
split up 7w into that
6w^2+7w-10=0
6w^2+12w-5w-10=0
group
(6w^2+12w)+(-5w-10)=0
undistribute factors
(6w)(w+2)+(-5)(w+2)=0
reverse distribute (ab+ac=a(b+c)
(w+2)((6w)+(-5))=0
(w+2)(6w-5)=0
set each to zero
w+2=0
subtract 2
w=-2
false, legnths cannot be negative
6w-5=0
add 5
6w=5
divide both sides by 6
w=5/6
subsitute
l=7+6w
l=7+6(5/6)
l=7+5
l=12
legnth=12 cm
width=5/6 cm
This does not appear to make sense, could you perhaps add signs such as multiplication, division, etc.
