The answer is 8
First you do what's in parentheses and that's 6 times 2 which equals 12
The you subtract by 4 which is 8
Answer:
5
Step-by-step explanation:
you add then all together to get 5
30 = 6 x 5
6 = 3 x 2
8 = 4 x 2
4 x 2 + 3 x 2 + 6 x 5 = 44
Answer:
$99
Step-by-step explanation:
100 - (100 x .10) = 90
90 + (90 x .10) = 99

Equation Given :
-------------------------------------------------------
16x² = 121
-------------------------------------------------------
Take away 121 from both sides:
-------------------------------------------------------
16x² - 121 = 0
-------------------------------------------------------
Make each term a perfect square
--------------------------------------------------------
(4x)² - (11)² = 0
--------------------------------------------------------
Apply algebraic rule : a² - b² = (a + b)(a - b)
--------------------------------------------------------
(4x + 11) (4x - 11) = 0
-------------------------------------------------------
Apply zero product property :
-------------------------------------------------------
4x + 11 = 0 or 4x - 11 = 0
--------------------------------------------------------
Solve for x :
--------------------------------------------------------
4x = - 11 or 4x = 11
x = -11/4 or x =11/4
--------------------------------------------------------------------------
Answer: x = -11/4 or x = 11/4
--------------------------------------------------------------------------
