Answer:
7 is the mean
Step-by-step explanation:
because you add 5 in Jan 8 in Feb 6 in Mar 9 in April and then divide by 4 because that how many numbers there are in total
5+8+6+9=28
28/4=7
divide 28 and 4
For this case we must indicate an expression equivalent to:
By definition of properties of powers and roots we have that:
![\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}](https://tex.z-dn.net/?f=%5Csqrt%20%5Bn%5D%20%7Ba%20%5E%20m%7D%20%3D%20a%20%5E%20%7B%5Cfrac%20%7Bm%7D%20%7Bn%7D%7D)
Then, we can rewrite the expression as:
Answer:
OPTION A
Answer:
14
Step-by-step explanation:
Two negatives equal a positive so
15+3-4
In order we solve from left to right
18-4
14
Our answer is 14!
3(4) + 12 + 12[4(6) - 10]
12 + 12 + 12(24 - 10)
12 + 12 + 288 - 120
192
(2x² + 6x + 10) + (4x² + 2x + 3)
Remove the parentheses and bring like terms together ( as there's a positive outside the parentheses the terms inside keep their signs):-
= 2x^2 + 4x^2 + 6x + 2x + 10 + 3
= 6x^2 + 8x + 13 answer
