Answer:
8.6
Step-by-step explanation:
The square root of 74 is 8.602325267. If you round this number to the nearest tenth you get 8.6
Remember to follow PEMDAS, and to only combine terms with like variables.
First, distribute the 2 to all terms within the parenthesis:
2(2p + 4t) = 2(2p) + 2(4t) = 4p + 8t
3 + 4p + 8t, or (D), is your answer choice, for it cannot be simplified anymore.

Answer:
A
Step-by-step explanation:
So we have the equation:
To solve for x, subtract 4 from both sides:
The left side cancels. Subtract on the right:
So, the value of x is 3.
And our answer is A.
And we're done!
The mean is the average.
Total the numbers and divide by the quantity of numbers.
2 +2 + 3 + 3 +4 +4 +4 +5 +5 +5 +5 + 6 = 48
48 / 12 = 4
The answer is B.4
