Answer:
B
Step-by-step explanation:
Cube root 1000x^6 = 10x^2
Cube root of - 27 = 3
So the first part of the factorization process is 10x^2 - 3. There is no help here because all of the answers give this binomial as the first factor.
The second factor is (10x^2)^2 + (3)*10x^2 + 3^2)
Expanding you get 100x^4 + 30x^2 + 9
Be very careful when looking at 100x^4 because that is where the answer is found.
It has to be B
The rope is 3 yards.
1 yard = 3 feet, so 9 ÷ 3 = 3 yards.

The value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.
<h3>What is an expression?</h3>
It is defined as the combination of constants and variables with mathematical operators.
The expression is:
= 13(a×b + a²) + 4
Plug a = 5
b = -3
= 13(5×(-3) + 5a²) + 4
= 13(-15 + 5(25)) + 4
= 13(-15 + 125) + 4
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.
= 13(110) + 4
= 1430 + 4
= 1434
Thus, the value of the expression 13(a×b + a²) + 4 is 1434 after plugging a = 5 and b = - 3.

-6 + 6 = 0
0 + -2x = 12 + 6 -2x = 12 + 6<span>4x+2(x-3)=8x+12 is our main problem right? so...
</span><span>4x + (-3 * 2 + x * 2) = 8x + 12
4x + (-6 + 2x) = 8x + 12
</span><span>So next we do:
</span><span>-6 + 4x + 2x = 8x + 12
Reorder the terms :) </span><span>-6 + 6x = 12 + 8x
</span>Now were going to solve for x
<span>-6 + -2x = 12 + 8x + -8x
</span><span>8x + -8x = 0
-6 + -2x = 12 + 0
-6 + -2x = 12
</span>-6 + 6 = 0
0 + -2x = 12 + 6
-2x = 12 + 6=
<span>-2x = 18
so now were just going to divide each side by -2
and so thats going to be like this
-2x = 18</span>
/ -2 /-2
0 -9
so whats left over is x = -9
So your answer is A.
