5 x 5/2 = 25/2
answer
25/2 units
Answer: 
Step-by-step explanation:
Given : In a sociology class there are 14 sociology majors and 11 non-sociology majors.
Total students = 14+11=25
Number of students are randomly selected = 3
Then, the number of ways to select 3 students from 25 students :-

Number of ways to select at least 2 of the 3 students re non-sociology majors :-

The probability that at least 2 of the 3 students selected are non-sociology majors will be :-

Answer:
a(x)=2x^2+9x+4
Step-by-step explanation:
We have been given the length and width, as well as the formula to find the area:
Length: 2x + 1
Width: x + 4
A = l * w
A = (2x + 1)(x + 4)
2x^2 + 8x + x + 4
We can add like terms now:
2x^2 + 9x + 4
Our area is 2x^2 + 9x + 4
Our answer would be a(x)=2x^2+9x+4
Answer : 4
Explanation : you minus the 2 on both sides bc they have the same "last name" by doing this you get 12 on the left and elimination 2 on the right which leaves you with 12=3x. Divide 3 on both sides which 12/3 =4 and ur left with x. So the final equation is 4=x
Answer:
i hope this helps, i got x + 5 ≤ 13 as ur equation
