The model represents a polynomial and its factors. An algebra tile configuration. 4 tiles are in the Factor 1 spot: 1 is labeled + x and 3 are labeled negative. 2 tiles are in the Factor 2 spot: 1 is labeled + x and 1 is labeled negative. 8 tiles are in the Product spot: 1 is labeled + x squared, 4 are labeled negative x, and 3 are labeled +. Which equation is represented by the model? x2 – 2x – 3 = (x – 3)(x + 1) x2 – 4x + 3 = (x – 3)(x – 1) x2 + 2x + 3 = (x + 3)(x – 1) x2 + 4x – 3 = (x + 3)(x + 1)

The correct answer on edge is actually B, I just took the quiz and c was wrong

Step-by-step explanation:

B.    x^2 – 4x + 3 = (x – 3)(x – 1)

Step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺

answer: y = 3/2 x - 3

y = 1/8 x - 3/4 that would be your correct option
