Answer:
x = 6 and DF = 3*6-3 = 15
Step-by-step explanation:
Given triangles are similar and their side lengths are proportional
the similarity ratio for this pair is 4/8 = 1/2
the length of DF:
(7.5)/(3x - 3) = 1/2 cross multiply expressions
3x - 3 = 15 add 3 to both sides
3x = 18 divide both sides by 2
x = 6 and DF = 3*6-3 = 15
Answer:
10x -4
Step-by-step explanation:
3+2(5x)-7
Multiply
3 +10x -7
Combine like terms
10x -4
2<3+x
subtract 3 on both sides
2-3<3-3+x
simplify
-1<x
this can also be rewritten as
x>-1
Simple....
so we have to determine if the value is less than the base....
.... is 8<2? No.
No....
Is 3<3? No....
No.....
No.....
