Answer:
B. x + 6
C. 4x - 1
Step-by-step explanation:
<em><u>To get the two binomials of the trinomial, you split the middle term, like so:</u></em>
<em><u /></em>
<em><u>Group:</u></em>
<em><u /></em>
<em><u>Take out the GCF (Greatest Common Factor):</u></em>
x(4x - 1) 6(4x - 1)
(x + 6) (4x - 1)
By solving given equations, the value of c is 30.
Given two equations
x + 2y = 10 and
3x + 6y = c
These lines represents the same line for some constant c.
Value of c:
x + 2y = 10-------------(1)
3x + 6y = c-------------(2)
Dividing equation (2) by 3
After solving the above equation, we get
x + 2y = c/3-----------(3)
Remember that a line is written as ax + by = c, in our case, both lines have a =1 and b = 2. Therefore, in orther that the two lines are equal, we need that, 10 = c/3
c = 10 × 3 = 30
c = 30
Therefore,
The value of c is 30.
