Negative 1 times the square root of 61 is -7.81
A. An integer is a whole number without decimals
If this is rounded to the nearest integer, the number is -8
B. Rounded to the nearest tenth is the first decimal place. Therefore the number would be -7.8.
2x^2 + 2y^2 + 2xy I think
Mean of a data = Sum of all observations ÷ Total number of observations
Mean of this data will be :
Sum of all observarions = 17 + 13 + 18 + 20 + 17 + 15 + 12 = 112
Total number of observations = 7
Mean = 112 ÷ 7
Mean = 16
Therefore the mean of this data set <em>=</em><em> </em><em>1</em><em>6</em><em> </em>
Answer:
x=-9
Step-by-step explanation:
first you make the coefficients equal to each other by doing a common factor which in this case is 5. Then you have to do the variable for each time the common number is repeated which is 5^x * 5^x= 5^(x+3)*5^(x+3)*5^(x+3) This would make it equal to 5^2x=5^(3x+9). Since the non exponents are common factors you can get rid of them and solve for the exponent by doing 2x=3x+9. You solve that equation to get x=-9.
