A slide with size 20 text font and one or two images.
change=100(63-58)/58
change=100(5/58)
change=500/58
change=250/29
change=8.62
Answer:
Step-by-step explanation:
(1): "a2" was replaced by "a^2"
((2a2 + 8ab) - 3a) - 12b
2a2 + 8ab - 3a - 12b
Is this a multiple choice
One approach is to express
8x2y
so that the numerator and denominator are expressed with the same base. Since 2 and 8 are both powers of 2, substituting 23 for 8 in the numerator of 8x2y gives
(23)x2y
which can be rewritten
23x2y
Since the numerator and denominator of have a common base, this expression can be rewritten as 2(3x−y). In the question, it states that 3x−y=12, so one can substitute 12 for the exponent, 3x−y, which means that
8x2y=212
The final answer is A.
