Step-by-step explanation:
hey the answer is 25.47 .....
what exactly do you want here?
Answer:
DF = 7.5
Step-by-step explanation:
Since the 3 sides are congruent, then
EF = DE , that is
4.5m - 42 = 1.5m - 9 ( subtract 1.5m from both sides )
3m - 42 = - 9 ( add 42 to both sides )
3m = 33 ( divide both sides by 3 )
m = 11
Thus
DE = 1.5m - 9 = 1.5(11) - 9 = 16.5 - 9 = 7.5
Then
DF = 7.5
Assuming your original expression was 3√(27x¹⁸), the answer is 9x⁹√(3).
We split up the radicand into perfect squares. Once we do, we take out the things that were squared:

Answer:
Infinitely many
Step-by-step explanation:
for example,
a triangle of 1 - 1 -
is 45 - 45 - 90 based on the 45-45-90 triangle theorem
if I multiply the three side lengths listed above by the same number, I will still have a 45 -45 -90 because of the definition of similar triangles
