DF=9x-39
DE=47
EF=3x+10
47+3x+10=9x-39
47+10+39=9x-3x
96=6x
16=x
Answer:
33
Step-by-step explanation:
The surface area of a solid is just the total area of all its faces. We know a cube has 6 identical faces with area s^2 where s is the side length.
So 6s^2 is the surface area. We can use this to find s.
6s^2 = 600
s^2 = 100
s = 10 cm
Answer:
.08
Step-by-step explanation:
Answer:
add 33 to both sides
Step-by-step explanation:
Given
-
x - 33 = 33 ( add 33 to both sides )
-
x = 66 ( multiply both sides by - 2 to clear the fraction )
x = - 132
