The original expression is given by:

The correct way to rewrite the expression is given by:

For this, we use two properties:
Associative property:
The way of grouping the factors does not change the result of the multiplication:
Commutative property:
The order of the factors does not vary the product:
9514 1404 393
Answer:
340
Step-by-step explanation:
The ratio of natural to synthetic is give as ...
5 : 8
Then the ratio of natural to total would be ...
5 : (5+8) = 5 : 13
The amount of natural oil in 884 total liters of oil will be ...
(5/13)(884 L) = 340 L
884 liters of Petrolyn oil will contain 340 liters of natural oil.
Answer:
C. (2x – 1)(2x + 1)
Step-by-step explanation:
4x² – 1 = (2x)(2x) – 1 = (2x – 1)(2x + 1)
To answer this question, we must find the slope of line b.
We have then:
b = (3 - (- 2)) / (2 - (- 3))
b = 5/5
b = 1
Since the lines b and c are parallel, it follows that their slopes are equal.
Then
mc = b = 1
Answer:
The slope of line c is:
mc = 1
So it would by 4/10. simplify that and its B. 2/5
