Answer:
[see below]
Step-by-step explanation:
V = s^3
V = (x+4)^3
V = x^3 + 3x^2 * 4 + 3x * 4^2 + 4^3
V = x^3 + 12x^2 + 48x + 64
Hope this helps.
Answer:
d) 16x² -56x +49
Step-by-step explanation:
The square of a binomial difference will have the form ...
(ax -b)² = a²x² -2abx +b²
__
The sign of the linear term will be negative, which eliminates choices A and C.
The linear term will be double the product of the roots of the other two terms.
In choice B, the linear term has a factor of 5 that appears nowhere else, so that cannot be a perfect square.
Choice D factors as ...
16x² -56x +49 = (4x -7)² . . . . the square of a difference
"a doll house" and “I Want a Wife,” by Judy Brady. Read the excerpt from the 1971 article. After reading the article, write a full, well-written paragraph which compares Brady with Nora at the end of the play. What points would Brady and Nora feel similarly about? How can you tell? If Brady were to differ from Nora, how do you think they would be unlike each other?
Answer: 3.886 m/s
Step-by-step explanation:
1 A.
The initial velocity (u) = 10 km/hr or 2.77 m/s
1 B.
The final velocity (v) = 60 km/hr or 16.66 m/s
1 C.
5 seconds.
1D. Acceleration = Final velocity - initial velocity / time
= 16.66 m/s - 2.77 m/s / 5 s
= 3.886 m/s.
