Answer:

always

Step-by-step explanation:

for the 2 sides to be equal then x must always be equal to a

given

x² = a² ( take square root of both sides )

\sqrt{x^2} = \sqrt{a^2} , that is

x = a

3x2 + 2(x2 – 20) = 16 - 2x2
lana66690 [7]

3x(2) + 2(2x - 20) = 16 - 2x(2)

6x + 4x - 40 = 16 - 4x

10x - 40 = 16 - 4x

14x - 40 = 16

14x = 56

x = 4

Hope this helps! ;)

Regina, courtney, and Ellen hiked around bear pond. Regina hiked 7/10 of the distance in an hour. Ellen hiked 3/8 of the distanc
Kitty [74]
7/10 > 3/8

I found this by first finding a common denominator, so for this it will be 40. 10 can go into 40 four times, so you do 7x4 and that is 28, so 7/10 is 28/40.
3/8 is 15/40 because 8 goes into 40 five times, so you do 5x3 which is 15, so the fraction is 15/40. 15/40 is less than 28/40 because 28 > 15
