Answer:
x=6
Step-by-step explanation:
Since it's a parallelogram both of these parallel sides are equal so you can set up an equation like this:
4x-8=2x+4
Now solve.
4x=2x+12
2x=12
x=6
Answer: One approach is to express
8x
2y
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
8x
2y
gives
(23)x
2y
which can be rewritten
23x
2y
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
8x
2y
=212
The final answer is A.
D) is your answer
Note that your answers is out of order. However, note that there are 3 groups of 7's. All other choices have either only one 7 or two 7. Therefore, D) is your correct answer.

Correct. 357 × 20 = 7,140 (Just make sure the 20 × 7 column is 140, not 14).
Checking this:
7,140 ÷ 20 = 357
Hope this helps!
Answer: it is equal
Step-by-step explanation: you subtract 15-4 which equals 11. the exponent is the only thing being subtracted since it's a fraction. therefore it equals 10(11)
