Additive inverses, because their sum is 0
Well it's 10 inches all the way around. So multiply 10 by 10 which is 100. So 100 inches area.
Answer:
x = -4/3 and x = 5/2.
Step-by-step explanation:
6x² - 7x = 20
6x² - 7x - 20 = 0
To solve this, we can use the quadratic formula to solve this.
[please ignore the A-hat; that is a bug]

In this case, a = 6, b = -7, and c = -20.

=
= -8 / 6 = -4 / 3
=
= 15 / 6 = 5 / 2
So, x = -4/3 and x = 5/2.
Hope this helps!
Step-by-step explanation:
1/6 (3 - 2x) < 1/3 x
let's multiply everything by 6
3 - 2x < 6/3 x
3 - 2x < 2x
3 < 4x
3/4 < x
so, x > 3/4
since 3/4 is never equal to x but is purely smaller than x, the interval of valid x values starts right after 3/4 and goes to infinity.
x = 3/4 is not valid, because 3/4 is not smaller than 3/4 (it is equal to) ...
