Mathematics

zepelin [54]3 years ago
5 0

Since 216 is the cube of 6, 64 is the cube of 4 and x^3 is the cube of x, we have

216x^3 + 64= (6x)^3+4^3

so the expression is the sum of the cubes of 6x and 4

bagirrra123 [75]
     9y - 5x = 20
or, (9y - 5x) / 20 = 1
or, 9/20 y - 1/4 x = 1
compare with x/a + y/b = 1
you'll get
x intercept (a) = -4
y intercept (b) = 20/9

NARA [144]

Answer:

Avoid Using too many statistics

Step-by-step explanation:

when a speaker is giving a speech, the listeners prefer main points to hearing too much of statistics. Too many statistics bore the audience and sometimes divert their attentions from the crux of the speech. If statistics are to be given, they must be clearly expressed and the source should be clearly stated.

Numbers that are of large decimal points can be rounded off so as not to confuse the audience and to make them grasp the main idea.
