Answer:
no
Step-by-step explanation:
(k-9)²
=(k-9)(k-9)
=k(k)-9(k)-9(k)-9(-9)
=k²-9k-9k+81
=k²-18k+81. As a result, the product of (k – 9)2 using the perfect square trinomial rule shown on the left is k²-18k+81. Hope it help!
6%
You want to calculate the interest on $12000 at 6% interest per year after 5 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $12000.00.
r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.
t is the time involved, 5....year(s) time periods.
So, t is 5....year time periods.
To find the simple interest, we multiply 12000 × 0.06 × 5 to get that:
The interest is: $3600.00
Answer:
1/5x+5
Step-by-step explanation:
Answer:
-45
Step-by-step explanation:
Let the number be represented by x.
The question can be solved as x/9 + 8 = 3
This is because the quotient of the number and 9 is same as (x/9)
and it is expected to be eight more (+ 8)
Therefore, x/9 = 3 - 8
x/9 = -5
x = -5 x 9
x = -45
