Answer:
A = x^2 + 5x - 14
Step-by-step explanation:
A = L × W
A = (x+7) × (x-2)
A = x^2 + 7x - 2x - 14
Answer: what is the question?
Step-by-step explanation:
the two ratios are equivalent beacuse 4/6 is not like a positive number so 4/6 and 14/21 are equivalent
(27 1/2)/10
(55/2)/10
55/20
11/4
2 3/4 oz per envelope
The association between the given lines is that they are 'neither perpendicular nor parallel.'
To prove, let's convert the given equations in their slope-intercept form i.e. 'y = mx + b'
-7x + 2y = 3
2y = 7x + 3
y = 7/2x + 3/2
-6x + 3y = 2
3y = 6x + 2
y = 2x + 2/3
This shows that both the lines have different slopes, as well as, intercepts of y. And,
= 2 * 7/2 ≠ -1
Thus, it is not perpendicular also.
Therefore, <u>option D</u> i.e. 'neither perpendicular nor parallel' is the correct answer.
