Answer:
The sum of this entire line is 180, so to solve this we would subtract 20 from 180, which means x = 160.

Answer:
Step-by-step explanation:
a. 16b^2c^12-0.25 can be rewritten as follows because it is the difference of two squares:
(4bc^6 - .5)(4bc^6 + .5)
b. 81x^6y^2-0.36a^2
is the difference of two squares, just like (a) (above); its factors are:
(9x^3y - 0.6a)(9x^3y + 0.6a)
The answer is 4 and 9, this is because 2*2=4 and 3*3=9, so their square roots are 2 and 3
It is true because every term is the previous term multiplied by -2. So, -40 x -2 = 80, 80 x -2 = -160
