Answer:
7 millimeters
Step-by-step explanation:
Volume is the area of the base times it's length.
140/10 is 14
so the area of the triangle is 14
the formula for area of a triangle is base times height divided by 2
so
d x 4/ 2 = 14
multiply both sides by 2
d x 4 = 28
divide both sides by 4
d=7
Answer:
2m + 22
Step-by-step explanation:
Use the distributive property.
2(m + 11)
2 x m = 2m
2 x 11 = 22
Therefore, 2m + 22
AC = 8.9
BC = 6.5
(90% angle)
8.9 x 6.5 = <span>57.85
57.85/2 = 28.925
Area of ^ABC = 28.925 cm squared
DE = 55.1
55.1/ 11.02 = 5
DEF is 5 times as big as ABC
DF = 44.5
FE = 32.5
44.5 x 32.5 = 1446.25
1446.25/2 = 723.125
I am not positive but I believe DEF = 723.125 cm squared
Good Luck on the Test!! :D

It depends on what type of Triangle or what the volume or area is. This question is missing information.
