Answer:
Distributive property
Explanation:
You are distributing the 3 to the parenthesis to get 12x+21 =43
<span>x^2-2x-24 = (x - 6)(x + 4)
cause
</span>(x - 6)(x + 4)
= x^2 - 6x + 4x - 24
= x^2 - 2x - 24
answer
(x - 6)(x + 4)

Answer:
3/10
Step-by-step explanation:
Subtract the sum of 1/3, 4/15 and 1/10 from 1:
10/30 + 8/30 + 3/30 = 21/30, or 7/10
Then: 1 - 7/10 = 3/10
precedence is:
1 Parentheses (simplify inside 'em)
2 Exponents
3 Multiplication and Division (from left to right)
4 Addition and Subtraction (from left to right)
(7+41) = 48
48 ÷ 2 = 24
24 -15 = 9
