Think of the squares of the whole numbers.
0^2 = 0
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
5^2 = 25
6^2 = 36
7^2 = 49
39 is between 36 and 49, so sqrt(39) is between 6 and 7.
Hi!
Explanation:<em> </em><u><em>First you had to add by 8 from both sides. Then simplify, you can subtract by 4x from both sides. Simplify again, you can divided by 2 and it gave us 2x/2=8/2. And the answer is x=4 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>
Answer:
g(x) = 3
Step-by-step explanation:
Simply substitute -4 in for x in the equation (as you can see -4 takes the place of x in g(-4), so just do the same thing for all of the other x's in the equations). Therefore, g(-4) = (-4) + 7. Well, since -4 is negative and 7 is positive, you can think of it as 7 - 4, which gets you 3. Voila! 3 is your answer :)
Answer:
6 3/4
Step-by-step explanation:
27/4
4 goes into 27 6 times
4*6 = 24
27-24 = 3 is the remainder
Put the remainder over the denominator
6 3/4
