The perimeter of a triangle with length of sides a, b and c:
P = a + b + c
a = 2, b = 5, c = 10x
Substitute:
P = 2 + 5 + 10x = 7 + 10x
<h3>Answer: 7 + 10x</h3>

Answer:
C) 15
Step-by-step explanation:
Here we have to use the combination to find the number of possible combinations.
Total number of classmates (n) = 6
We are selecting 2 individuals. So r = 2.
The combination formula nCr = 
Plug in n = 6 and r =2, in the above formula, we get
= 
= 
Simplifying the above factorial, we get
= 15
So the answer is C) 15
Answer:
a = 10.36m
B = 47.7º
C = 90º
Step-by-step explanation:
we know the angle of A so we do the sin of A; Spoiler: its 0.67
0.67 = a / 15.4
0.67 * 15.4 = a
a = 10.36
----------
B = 90 - 42.3 = 47.7º
Let x = the minutes that Tom has remaining before exceeding 500 minutes.
Because he has already used 230 minutes, the total minutes he has is
x + 230
We want this total to be less than or equal to 500 minutes.
Therefore
x + 230 ≤ 500
Answer: x + 230 ≤ 500
