Answer:
-9 and -10
Step-by-step explanation:
![- \sqrt{92 }](https://tex.z-dn.net/?f=%20-%20%20%5Csqrt%7B92%20%7D%20)
= -9.591...
It is in between the integers -9 and -10.
Simple the answer is: n=14
Answer:z=1/9w
Step-by-step explanation:
Area of a rectangle=length×width. If the area is 161 and the length is 14 then that means: 161=14×width. You would then divide 161÷14 and you will find that the width is 11.5.
Answer:
![-8x^2 - 4x + 29 \\](https://tex.z-dn.net/?f=-8x%5E2%20-%204x%20%2B%2029%20%20%5C%5C)
Step-by-step explanation:
Second expression evaluates to:
(1)
For (1) We are using the rule ![(a+b)^2 = a^2 +2ab + b^2\\\\](https://tex.z-dn.net/?f=%28a%2Bb%29%5E2%20%3D%20a%5E2%20%2B2ab%20%2B%20b%5E2%5C%5C%5C%5C)
Here ![a = -x, b = 5\\\\](https://tex.z-dn.net/?f=a%20%3D%20-x%2C%20b%20%3D%205%5C%5C%5C%5C)
First expression evaluates to
(2)
Subtract (2) from (1)
![x^2 - 10x +25 - (9x^2 -6x -4) = x^2-9x^2 -10x - (-6x) +25 -(-4)\\\\= -8x^2 - 4x + 29 \\](https://tex.z-dn.net/?f=x%5E2%20-%2010x%20%2B25%20-%20%289x%5E2%20-6x%20-4%29%20%3D%20x%5E2-9x%5E2%20-10x%20-%20%28-6x%29%20%2B25%20-%28-4%29%5C%5C%5C%5C%3D%20-8x%5E2%20-%204x%20%2B%2029%20%20%5C%5C)
