Answer:
(y + 7i)(y - 7i)
Step-by-step explanation:
It cannot be factored using real numbers, but consider
7i × - 7i
= -49i² and i² = - 1
= 49
The factoring as a difference of squares to obtain
y² + 49 = (y + 7i)(y - 7i)
10 km in .5 hour. Since it is the same as 20 km in 1 hour. Multiplied by 2.
20 is greater than 15.

Answer:
10 years
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
t = 100 / ( 500 × 0.02 ) = 10
t = 10 years
The time required to
accumulate simple interest of $ 100.00
from a principal of $ 500.00
at an interest rate of 2% per year
is 10 years.
