Answer:
x = 9
Step-by-step explanation:
angle 1 plus angle 2 equals 90 because they are complementary. combining like terms gives you 8x + 18 = 90. then you get 8x = 72, which means that x equals 9
Answer:
Option D.
Step-by-step explanation:
The given expression is
It is a polynomial.
(x-c) is a linear factor of polynomial p(x) if p(c)=0.
Substitute x=-1 in the given expression.
It means (x+1) is not a linear factor of given expression.
Substitute x=-2 in the given expression.
It means (x+2) is not a linear factor of given expression.
Substitute x=-4 in the given expression.
It means (x+4) is not a linear factor of given expression.
None of the given options are a linear factor of given expression.
Therefore, the correct option is D.

Step-by-step explanation:
As it is proved that the equation has no solution, Derick is correct
Step-by-step explanation:
Given
We have to solve the equation in order to check if Derick was solved the equation correctly or not.
So,
Applying distributive property first
As the variable is already cancelled in the equation there is no unique solution.
In order for an equation to have infinite solutions the constant on both sides of equation should be same which is not the case in the given equation
So,
As it is proved that the equation has no solution, Derick is correct
