Answer:
d. 40 units
Step-by-step explanation:
The length of the horizontal side of this rectangle on the line y=20 is the difference of the x-coordinates, 12 and 20, so is 8. The length of the vertical side on the line x=20 is the difference of the y-coordinates, 20 and 8, so is 12.
Two sides are of length 8 and two are of length 12. The perimeter is the sum of the side lengths, so is ...
P = 2·8 +2·12 = 40 . . . units

Answer:</h3>
B). y = (x -3)(x +1)(x -1)
<h3>
Step-by-step explanation:</h3>
The zeros of the function are -1, 1, and 3, so the factors are (x +1), (x -1), and (x -3).
Selection B is the only choice that has these three factors.

<em>Comment on zeros and factors</em>
When x = a is a zero of a polynomial function, (x -a) is a factor.
7x+(x+20)=180
Just simplify. Hope this helped:)
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
5.2v - (30 ÷ 6) + 12
<u>9) We need to determine which part of the expression represents a quotient?</u>
We know that when we divide one rational expression by another, the result would be termed as 'quotient'.
Here, it is clear that:
(30 ÷ 6) represents the expression part for a quotient.
When we divide 30 by 6, we get the result 5 which would be the quotient of the expression 30 ÷ 6.
10. Which part of the expression represents a product of two factors?
We know that when a multiply two number, we get the product. The multiplying numbers are the factors of the product.
For example, 4 × 9 = 36 therefore, 4 and 9 are the factors of 36.
In our case, 5.2v represents a product of two factors 5.2 and v. In other words, 5.2 and v are the factors of the product of 5.2v.
