Answer:
a = -5
Step-by-step explanation:
To solve for A we must get A on one side of the equation by itself. So, we must divide 30 by 6.

The answer is: B (-1 3/4, -1 2/3, -1.25, -5%)
Answer:
To make given quadratic equation a whole number , we have to add 6 in the equation.. (3 x - 4 )²
Step-by-step explanation:
The given quadratic equation is
9 x² - 24 x + 10 = 0
(3 x )² - 24 x + 10 = 0
(3 x )² - ( 2 × 3 x × 4 ) + 10 = 0
Now if we add 6 to the equation , it will become whole square as (a + b)²
I.e (3 x )² - ( 2 × 3 x × 4 ) + 10 + 6 = 0
Or, (3 x )² - ( 2 × 3 x × 4 )+ 16 = 0
Or, 9 x² - 24 x + 16 = 0
Or, (3 x - 4 )² = 0
Hence to make given quadratic equation a whole number , we have to add 6 in the equation.. Answer
This is a ratio problem. You only need solve the ratio of the sand.

7,488 pounds
To check: The pool deck is 156 times larger than the original amount of concrete so the amount of sand needs to be 156 times more.
