multiply polynomials
(2n+2)(6n+1)
The multiplication of the expression ( 2n + 2 )( 6n + 1 ) is 12n² + 14n + 2.
Given the expression in the question:
( 2n + 2 )( 6n + 1 )
To multiply the expression ( 2n + 2 )( 6n + 1 ), we use the distributive property and the FOIL method.
( 2n + 2 )( 6n + 1 )
Using the Foil method:
2n( 6n + 1 ) + 2( 6n + 1 )
Using the distributive property:
2n × 6n + 2 × 1 + 2 × 6n + 2 × 1
Multiplying, we get:
12n² + 2n + 12n + 2
Collect and add the like terms:
12n² + 14n + 2
Therefore, the simplified form is 12n² + 14n + 2.

B. describe in words what happens to the x coordinates and y coordinates of the original triangle's vertices as a result of this reflection
Answer:
(-1,3) (-3,1) and (-4,5)
Step-by-step explanation:
Given is a triangle ABC with coordinates (1,3)(3,1) (4,5)
First transformation is reflection over yaxis i.e. x=0
Reflection in the y -axis: A reflection of a point over the y -axis is shown. The rule for a reflection over the y -axis is (x,y)→(−x,y)
Hence x coordinate will change sign
The resulting coordinates would be
(-1,3) (-3,1) and (-4,5) respectively
y coordinates will remain the same because of this reflection.
Hence new coordinates would be
(-1,3) (-3,1) and (-4,5) For A, B and C in the same order
Robin’s graph is a reflection of Giselle’s graph over the y-axis.
Robin’s graph is a translation of Giselle’s graph 1 unit down.
Robin’s graph is a translation of Giselle’s graph 1 unit left.
Answer:
First Option
Step-by-step explanation:
The graphs that match the function given are:
(a) VI, (b) III, (c) I, (d) II, (e) V, (f) IV
Consider the equations of the graphs given :
(a) y = 0.5 x²
This is a quadratic equation and thus will be a parabola.
This matches VI.
y is directly proportional to the square of x.
(b) y = 5/x²
Here negative values of y are not possible since x is squared.
Also, the values of y will be equal to a and -a.
This matches III.
y is inversely proportional to the square of x.
(c) y = x³
Here negative values of x will have the y values also negative.
Also, the value increases when x increases.
This matches I.
y is directly proportional to the cube of x.
(d) y = 1/x³
y value for x = -a is the negative of the y value for x = a.
Also, as x increases y decreases.
The function is not defined at 0.
This matches II.
y is inversely proportional to the cube of x.
(e) y = 3√x
Here since x is inside the cube, not defined for negative values of x.
As x increases, y also increases.
This matches V.
y is directly proportional to the square root of x.
(f) y = (0.5)ˣ
For negative values o x, the value of y will be high and for positive values of x, the value of y will be lower.
This matches IV.
y is exponentially related to x.
