Answer:
a = 1
Step-by-step explanation:
The problem is written as a linear equation:
((1/8)^-3)a = 512
512a = 512 . . . . simplify
a = 1 . . . . . . . . . divide by the coefficient of a
___
We suspect you might intend the exponential equation:
(1/8)^(-3a) = 512
512^a = 512 . . . . . simplify
a = 1 . . . . . . . . . . . compare bases and exponents
equivalently, take the log to the base 512:
a·1 = 1
a = 1
Answer:
C. 6x² + 12xy
Step-by-step explanation:
Distribute the 3x to both terms in the parenthesis by multiplying them together...
3x(2x) + 3x(4y)
6x² + 12xy
Answer:
(4x2 - 2x) - (-5x2 - 8x)
= 4x2 - 2x + 5x2 + 8x.
= 4x2 + 5x2 - 2x + 8x.
= 9x2 + 6x.
= 3x(3x + 2).
Answer: 3x(3x + 2)
