Amanda and Trinity each wrote an expression, but only Amanda’s expression is equivalent to 2x+5. What could be Trinity’s expression? A

2(x+3)−1

B

5x−3(x−1)

C

5(x+1)−3x

D

3x−(x−5)

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer: 48

just remember to use pemdas:

parentheses

multiplication

division

addition

subtraction

the image is given below

since the options are not given so we draw it from the equation

the given equation is

y = (x-1) (x+4)

y = y² + 3x - 4

the above equation is a quadratic equation which will have two roots. if we draw the graph for it, it will look like this
