Answer:
<em>The length of the side along the river is 140 m</em>
Step-by-step explanation:
<u>Equations</u>
To solve the problem, we need to recall the area of a trapezium is:
Where b1 and b2 are the lengths of the parallel sides and h is the height of the trapezium.
The field to be bought by Mohan has a trapezium shape with a side along the road of side x and a side along the river of side 2x, as stated in the problem.
Knowing the height is h=100 m, and the area is 10500 m2:
Simplifying:
Dividing by 150:
x = 70 m
2x = 140 m
The length of the side along the river is 140 m
Answer:
The triangles are congruent because:
- QP = ST
- angle P = angle T
- the side PT is in both triangles
We know when 2 sides of two triangles and the angle between them is congruent, the triangles are congruent.
Answer:
9(r + 8) = 9r +72
Step-by-step explanation:
9(r + 8)
9r + 72
Hope this helps!
F(x)=-2e^x
x=3
f(3)=-2e^3
pemdas so exponents first
e^3
e=2.718281828454590
cube that
20.0855
now we have
-2 times 20.0855=-40.1711
answer should be -40.1711
(I see what you did wrong, if -6=-2 times e^3, divide -2, 3=e^3, maybe you just put -2 times 3 by mistake)
Answer: if solving for x....
x= 6
Step-by-step explanation:
2x-5=7
2x-5+5=7+5
2x-5+5=7+5
2x/2= 12/2
x= 6
