The given identity tells you ...
.. (sum of numbers) * (sum of squares - product) = (sum of cubes)
Substituting the given information, you have
.. (sum of numbers) * (29 -10) = 133
Then you can divide by (29 -10) to get
.. sum of numbers = 133/19 = 7
The sum of the two numbers is 7.

Answer:
x = 40 degrees
Step-by-step explanation:
We are given that AB and CD are parallel to each other and they are cut by a transversal.
The angle 40 is complementary to angle z, so this means that they have the same measure by the complementary angles theorem.
Complementary are angles that occupy the same space on one parallel line compared to the other parallel line.
Angle z = 40 degrees
Answer:
d = log 38/log31
d = 1.06
Step-by-step explanation:
31 ^ d = 38
Take log of both sides since the exponential equation have different base (always)
d log 31 = log 38
d = log 38 / log 31
d = 1.58 / 1.491
d = 1.06.
We can actually check to see if this is correct.
Substituting d = 1.06
31^ 1.06 = 38.092
(You see, that's approximately correct)
Keep learning, maths is fun!
