Answer: $\huge\boxed{\boxed{15}}$

Step-by-step explanation:

Given expression

$\large\boxed{\frac{12[30 - (9+4^2)]}{|10|-|-6| } }$

Simplify the exponents

$\large\boxed{=\frac{12[30 - (9+16)]}{|10|-|-6| } }$

Simplify values in the parenthesis

$\large\boxed{=\frac{12[30 - 25]}{|10|-|-6| } }$

$\large\boxed{=\frac{12[5]}{|10|-|-6| } }$

Simplify absolute values (all positive)

$\large\boxed{=\frac{12[5]}{10-6 } }$

$\large\boxed{=\frac{12[5]}{4 } }$

Simplify by division

$\large\boxed{=3~[5]}$

Simplify by multiplication

$\huge\boxed{\boxed{=15}}$

Hope this helps!! :)

1.) Explain how u can use absolute value to tell whether the sum of two integers is positive or negative?

stealth61 [152]

Answer:

To find the sum of a positive and a negative integer, take the absolute value of each integer and then subtract these values. The result takes the sign of the integer with the larger absolute value. The sum of any integer and its opposite is equal to zero.
