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

Sorry. If I’m late! & Explanation? I just took the test Nd scored an 100%
If you are solving for x then here’s how:
(3x2 + 4x - 12) = (x + 5)
Remove the x on the left by remove one x from both of the sides.
(3x2 + 3x - 12) = 5
Add 12 onto both sides
(3x2 + 3x) = 17
Multiply
(6 + 3x) = 17
Take away 6 from both sides
3x = 11
Divide by 3 on both sides
x = 3.666 recurring
