Which ones? which months?
Step-by-step explanation:
(2a+3b)(4a²-6ab+9b²
(2a+3b){(2a)²-2a×3b+(3b)²}
Because (a³+b³)=(a+b)(a²-ab+b²)
Therefore,
(2a+3b){(2a)²-2a×3b+(3b)²}
=(2a)³+(3b)³
By substituting the values , we get
- (2a)³+(3b)³
- (2×3)³+(3×(-5))³
- 6³+(-15)³
- 216+(-3375)
- 216-3375
- -3159
Answer:
71.4699, 81.7301.
Step-by-step explanation:
So, the following are the scores: 74
90
84
78
61
65
62
67
73
75
76
95
71
98
80
The length of the score : 15
Then, let the size of the scores be n : 15.
Then, we have to find the mean.
Answer:
(B) -6
Step-by-step explanation:
If D is to be a functions, the value of x cannot repeat any of the other values listed first in the ordered pairs. Values of 6, 8, and -3 must be rejected. The only remaining answer choice is -6.
the slope of the given line is 2/3. The slope of a line perpendicular to this given line is the negative reciprocal of 2/3, or -3/2.
The line passes thru (6,4). We can immediately write the desired equation as follows:
y - 4 = (-3/2)(x-6). This could, of course, be written differently:
y = 4 - (3/2)x + 9, or y = (-3/2)x + 9 (in slope-intercept form).
