It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.
n + n + 5 = 41 (4) 5n + n + 1 = 41
<em>n and "5 larger than n"
</em>
'5 larger than n' = equivalent to n + 5
We now have n + n + 5
The problem says 41, thus;
<em>n + n + 5 = 41</em>
the correct answer for this is the last choice:
It is incorrect because the length of the unknown side is the square root of 7,225.
Your answer is h (20’mm) x^c’’
Answer:
-7
Step-by-step explanation:
f(3) = 2(3)+3 = 9
g(4) = 2^4 = 16
9 - 16 = -7
