Which polynomial expression represents a sum of cubes? (6 – s)(s2 + 6s + 36) (6 + s)(s2 – 6s – 36) (6 + s)(s2 – 6s + 36) (6 + s)

Nadusha1986 [10]

Answer:

Option 3 is correct that is $(6+s)(s^2-6s+36)$

Step-by-step explanation:

We have general formula for sum of cube which is

$a^3+b^3=(a+b)(a^2+b^2-ab)$

Here, we have a=s and b=6

on substituting the values in the formula we will get

$6^3+s^3=(6+s)(s^2+6^2-6s)$

After simplification we will get

$6^3+s^3=(6+s)(s^2+36-6s)$

After rearranging the terms we will get

$6^3+s^3=(6+s)(s^2-6s+36)$ which exactly matches option 3 in the given options.

Therefore, option 3 is correct that is $(6+s)(s^2-6s+36)$

a factory manufactures a metal piece in 32 minutes now technology allowed the factory to cut the time by 8% then another Improve

aliya0001 [1]

Answer:

28 minutes

Step-by-step explanation:

First you have to find what 8% off of 32 is

If you take away 8% of 100% you have 92%

In order to find 92% of 32 you must divide 92 by 100 and multiply it by 32

.92 x 32 = 29.44

Then you have to take off another 5%

Of you take 5% off of 100% you have 95%

.95 x 29.44 =27.97

Then round to the nearest minute

28 minutes
