Answer:
(20+2) (20-2) = 20² - 2²
20² - 2² = 396
Step-by-step explanation:
from the rule of the difference of two square which states thate
(a + b)(a − b) = a² − b²
therefore, 22 can also be written as (20 + 2),
while 18 can be written as (20 -2)
therefore by the rule of the difference of two square the product of both expression will give
(20+2) (20-2) = 20² - 2² = 400 - 4 = 396
So 45 in 30mins
we ususlly want to make the smallest number equal to one or as close to one as possible so
45/30=3/3 times 15/10
3/3=1
1 times 15/10=15/10
15/10=5/5 times 3/2
5/5=1
1 times 3/2=3/2
3 divided by 2 is 1.5

Both claims are false. In fact, 
and 
are one the multiplicative inverse of the other. This means, by definition of multiplicative inverse, that
So, it doesn't matter if is positive or negative: the multiplication of one number and its inverse will always be 1: for example,
Similarly, when you multiply two number, the sign of the product depends on the sign of the factors as follows:
So, the multiplication of two negative numbers is a positive number.
