HIGHSCHOOL ALGEBRA!!!!! PLS HELP :) <br> Find the root of the equation: (6x–1)(6x+1) - 4x(9x+2) = −1

My name is Ann [436]

(6x–1)(6x+1) - 4x(9x+2) = −1

Simplify the left side:

36x^2-1 -36x^2-8x = -1

Combine like terms:

-1 -8x = -1

Add 1 to both sides:

-8x = 0

Divide both sides by -8:

x = 0 / -8

x = 0

The root is 0

Write an absolute value inequality that describes the acceptable weights, w, of a 20-ounce bottle of sports drink.

Shtirlitz [24]

Answer: $0\leq w\leq 20$

Step-by-step explanation:

Since, Here w represents the weight of the bottle.

And, According to the question, he acceptable weights, w, of a 20-ounce bottle of sports drink.

That is, weight of the bottle can not be higher than 20 or the it can be atleast 20.

Therefore, $w\leq 20$

And, the weight can not be negative.

Therefore, $0\leq w$

Thus, the required inequality is,

$0\leq w\leq 20$
