The answer is A
Explanation-
3x + 4= 2x + 6
-4 = -4
3x=2x + 4
-2x= -2x
X=4
Answer:
I think it is either the first or second answer
Step-by-step explanation:
Answer:
The factors are 
Step-by-step explanation:
Given that 
are the zeroes of the polynomial
Let the polynomial be 
For the polynomial , If r is a zero of then 
will be a factor of P(x).
If 
is a factor of P(x) then r will be a zero of P(x).
From the given Zeroes we can write it in form of factors as below:
Answer:
its 7
Step-by-step explanation:
In equation, let x be the number of male students
a be the number of adults
y be the number of female students.
x= 7a+1
a= x/7 -1
y= x/2 or (7a + 1)/ 2
a + b = 82, let b be the number of students.
a + (x + y) = 82
a + [7a+1 + (7a+1)/2] = 82
a + [{2(7a+1) + 7a+1} / 2] = 82
a + [(14a +2 + 7a +1) / 2] = 82
a + [(21a + 3) / 2] = 82
(2a+ 21a + 3) / 2 = 82
(23a + 3) / 2 = 82
23a + 3 = 164
23a = 164 -3
23a = 161
a = 7
x = 7(7) +1, 49+1 = 50 male students
y=x/2, 50/2, 25 female students
50(male students) + 25(female students) + 7 (adults) = 82
