How many distinct triangles can be drawn by using three of the seven dots below? (Two triangles are considered different if they

jeka57 [31]

Answer:

35triangles

Step-by-step explanation:

Given

Total distinct points = 7

If we are to form triangles using the dots,

Total points in a triangle = 3

Using the combination rule;

number of triangles formed = 7C3

7C3 = 7!/(7-3)!3!

7C3 = 7!/4!3!

7C3 = 7*6*5*4!/4!3!

7C3 = 7*6*5/6

7C3 = 7*5

7C3 = 35

Hence the amount of triangles that can be formed is 35triangles

(3v^4 - 2) - (7v^4 + 6)

Lera25 [3.4K]

So firstly, you want to foil - (7v^4 + 6) [Think of the minus sign as -1]: $3v^4 - 2 - 7v^4 - 6$

Next, combine like terms and your answer will be: $-4v^4-8$
