Answer:
can you help me on my question
Hey there! :)
-(3x)² + 3 = -6
Simplify.
-(9x²) + 3 = -6
Simplify.
-9x² + 3 = -6
Subtract 3 from both sides.
-9x² = -6 - 3
Simplify.
-9x² = -9
Divide -9 from both sides.
-9x² ÷ -9 = -9 ÷ -9
Simplify.
x² = 1
So, x = 1 OR x = -1
~Hope I helped!~
To divide the expression we proceed as follows:
12x⁴y²÷3x³y⁵
=12x⁴y²/3x³y⁵
=(12÷3)×(x⁴÷x³)×(y²÷y⁵)
when you divide number with the same base, you subtract the numerators:
=4×(x⁴⁻³)×(y²⁻⁵)
simplifying this we get
=4xy⁻³
Answer: 4xy⁻³
Answer:
Median = 7; Mode = None; Mean = 7.14
Step-by-step explanation:
Measures of Central Tendency represent the distribution of a set of numbers or data. Median represents the middle number when ordered from least to greatest, Mode represents the most occuring number and Mean represents the average. In this case, the first step is to number the data set in order from least to greatest (2, 5, 6, 7, 8, 10, 12). Then you find the middle number in the set of data, which in this case is 7. Next, you look for the most occuring number, but since all numbers in this data set occur only once each, there is no Mode. Mean is the average, or the sum of all the numbers divided by the total numbers in the data set (50/7), or 7.14.
Assuming the sum of the opposite angle would be 180. We can easily calculate for x and ultimately solve for the angle of B. We do as follows
B + D = 180
3x-12 + x = 180
4x - 12 = 180
4x = 192
x = 48 degrees
Therefore angle B would have a measurement of 132 degrees. Hope this helps.
