Answer:
Step-by-step explanation:
1.) 6C4= 15
2.) (1C1)*(6C3)= 20
3.) (2C2)*(6C2)= 15
Y-4=5(x-6)
y-4=5x-30
5x-y=26
5x+(-1)y=26
Answer:
A) P = 6n + 8
Step-by-step explanation:
Given:
Perimeter of the 1 triangle = 24
Perimeter of the 2 triangle = 30
Perimeter of the 3 triangle = 36
Let's check with option A.
P = 6n + 18, where "n" is the number in the figure.
Plug in n = 1, we get
P = 6(1) + 18
= 6 +18
P = 25 True.
Plug in n =2, we get
P = 6(2) + 18
= 12 +18
P = 30 True.
Plug in n =3, we get
P = 6(3) + 18
P = 18 + 18
P = 36, true.
Therefore, the answer is A. P = 6n + 18
Thank you.
