Answer:
1/10
Step-by-step explanation:
1/2 - 2/5
common denominator is 10 (2x5)
5/10 - 4/10 = 1/10
Using the Fundamental Counting Theorem, the number of potential outcomes is given by: 
<h3>What is the Fundamental Counting Theorem?</h3>
It is a theorem that states that if there are n things, each with
ways to be done, each thing independent of the other, the number of ways they can be done is:

There are five decisions, each with four options, hence:

The number of options is:

Answer:
D) 82 units
Step-by-step explanation:
ΔBCD ≅ ΔEFG
In congruent triangles, corresponding parts are congruent
BD = EG
4x - 9 = 2x + 15
4x - 9 -2x = 15
2x - 9 = 15
2x = 15 +9
2x = 24
x = 24/2
x = 12
EG = 2x + 15 = 2*12 + 15
= 24 + 15
EG = 39 units
FE = CB = 17 units
Perimeter of ΔEFG = FE + EG + GF
= 17 + 39 + 26
= 82 units
