Answer:
B
Step-by-step explanation:
I think the answer is B because the expression shows 3 times x (Representing the number), and the diagram shows 3 xs. I was very confused about the first diagram but I still think it's B. Sorry if I'm wrong.
The complete factorization of the polynomial x² – x – 12 is (x – 4)(x + 3). The 3 positive unit tiles. Then the correct option is B.
<h3>What is polynomial?</h3>
Polynomial is an algebraic expression that consists of variables and coefficients. Variable are called unknown. We can apply arithmetic operations such as addition, subtraction, etc. But not divisible by variable.
The partial factorization of x² – x – 12 is modeled with polynomial tiles.
The factorization will be
x² – x – 12
x² – 4x +3x – 12
(x – 4)(x + 3)
The complete factorization of the polynomial x² – x – 12 is (x – 4)(x + 3). The 3 positive unit tiles. Then the correct option is B.

Answer:
x > 2 and x < -2
Step-by-step explanation:
Answer: B. Shifts right 5
Explanation:
When the number after the variable is in the parentheses, the transformation will be opposite of the sign. In this problem, the sign for 5 is negative so you would be going right 5 units because right is positive so that would be the opposite of the sign.
Monday : x
tuesday : 3x
wednesday : 3x - 20 = 40
thursday: 20
3x - 20 = 40
3x = 40 + 20
3x = 60
x = 60/3
x = 20
monday : 20 minutes
tuesday : 3x....3(20) = 60 minutes
wednesday : 40 minutes
thursday: 20
for a total of : 140 minutes <===
