Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle. Hope this helps :))
Answer:
1) Cubic
2) 2
3) -3
4) 
5) 
Step-by-step explanation:
The given polynomial is:

The degree i.e. the highest exponent of the variable involved is 3. So the polynomial is a Cubic polynomial.
The terms in a polynomial can be distinguished by addition and subtraction symbols. So, for the given polynomial there are 2 terms.
The constant term is the term without any variable. So the constant term in given polynomial is -3.
Leading term is the term with variable having highest exponet which defines the degree of the polynomial. So leading term of the given polynomial is 
Leading coefficient is the coefficient of the leading term. So for given polynomial the leading coefficient would be 
Answer:
x = 11
Step-by-step explanation:
The student didn't divide two on both sides in the step 1. This the mistake that the student made.
The correct solution
2√( 3x + 3 ) = 12
Divide 2 on both sides,
2√( 3x + 3 ) / 2 = 12 / 2
√( 3x + 3 ) = 6
Square on both sides,
[ √( 3x + 3 ) ]² = 6²
3x + 3 = 36
3x = 36 - 3
3x = 33
x = 33 / 3
x = 11
