6.28 (equation for circle perimeter is 2πr)
Answer:
The Blue box is your answer
Step-by-step explanation:
Multiply 4, 8, and 7 and you get 224. The problem states that it should not be over 250, and 224 is not over 250. So the blue box is your best go.
Answer:
<em>Option D</em>
Step-by-step explanation:
Take a look at the steps below;
To derive the second step we multiplied either side by 4, and as the 4 and 4 cancel each other out on one side of the equation, the other side being 4 * 4 = 16, we receive 6 + n = 16. The third step was found through the subtraction of 6 on either side of the equal sign. 16 - 6 = 10, so your <em>solution is Option D</em>
Answer:
1/8
Step-by-step explanation:
You're trying to make the coefficient of x equal 1
Answer:
905
Step-by-step explanation:
So your original equation is f(x) = x² + 5
First lets work with the stuff inside the parentheses.
f(5) = 5² + 5 = 30
So now you are finding,
f(f(5)) => f(30)
f(30) = 30² + 5 = 900 + 5 = 905
