Answer:
x(x + 8)(x - 8)
Step-by-step explanation:
Given
x³ - 64x ← factor out x from each term
= x(x² - 64) ← x² - 64 is a difference of squares
= x(x + 8)(x - 8) ← in factored form
Okay so...
There are 21 groups of 3.
21 x 3 = 63.
63 people are in the room.
Answer:
3x^2 + 3xz + 2y^2 - 2yz - xy
Step-by-step explanation:
(1) multiply it to get
3x^2 - 3xy + 3xz and 2yx + 2y^2 - 2yz
add similar variables (-3xy + 2yx)
( the order of the variables doesn't matter xy or yx is the same)
we get -xy
and then after that simplifying we get 3x^2 + 3xz + 2y^2 - 2yz - xy
Answer:
62.5 interest on 2500 loan
Step-by-step explanation:
Given that,
amount of loan bank has granted = 2500
number of years = 90 days
90 days = 3 month
3 months = 1/4 year = 0.25 year
interest rate = 10%
= 10 / 100
= 0.1
Formula to use
Principal * interest rate expressed as a decimal * time in years
2500 * 0.1 * 0.25
62.5
Hence, the interest on the loan of 2500 with 10% interest rate for 90 days is 62.5
