Point F is the midpoint of segment DE. DF = 2x+6 and DE = 2x+36. Find DE.
1 answer:
Answer: It already tells you what DE= 60
Step-by-step explanation:
Since F is the midpoint of DE that means DF=FE
So create equation
When DF and FE is added your answer should equal DE
So you write the equation to find x and once x is found substitute your answer for x
subtract 12 on both sides 36-12= 24
subtract 2x on both sides 4x-2x=2x
divide 2 into both sides 24/2=12 x=12
4x12=48+12=60 2x12=24+36=60

Answer:
30 cubic feet
Step-by-step explanation:
Here we are given the volume of rectangular pyramid as 90 cubic feet as we are required to find the volume of rectangular prism.
For that we need to use the theorem which says that
the volume prism is always one third of the volume of the pyramid . Whether it is rectangular of triangular base. Hence in this case also the volume of the rectangular prism will be one third of the volume of the rectangular pyramid.
Volume of Rectangular prism = * Volume of rectangular pyramid
= * 90
= 30
