Answer:
a. 79
Step-by-step explanation:
Use this theorem
![x = \frac{101 + 57}{2 } \\ x = \frac{158}{2} \\ x = 79](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B101%20%2B%2057%7D%7B2%20%7D%20%20%5C%5C%20x%20%3D%20%20%5Cfrac%7B158%7D%7B2%7D%20%20%5C%5C%20x%20%3D%2079)
Add 7 to Y and 5 To x he would be square root of 74
The formula for compound interest is : A = P(1+r/n)^nt
A = 4000 (1+0.021/4)^4x4
A = 4000 (1.021)^16
A = 5,577.91
Sergio's total interest would be : 5,577.91 - 4,000 = $ 1,577.91
hope this helps
Solve what? (ugh why is there a least amount of character limit)
Answer:
x +5
Step-by-step explanation:
Time to simplify!
The answer is x +5
We can do long division to solve this
x^2 + 7x + 10.
------------------
x + 2
The x cancel out and we have x.
10/2 = 5, so now we get x + 5
