Answer: B
Step-by-step explanation: You make the values in the parentheses equal to zero.
(X + 3) = 0
X = -3
A is wrong because the root would be 3, not negative 3. C is wrong because 3 isn’t guaranteed to be a root. D is wrong because -3 is a real solution.

I believe your answer is:
The square root of 5 () is irrational.

Here’s why:
- A <em>rational number</em> is a number that can be rewritten as <u>a fraction of two integers with a </u><u>nonzero </u><u>denominator</u>.
- <em>Rational numbers </em>include<em><u> integers, fractions, terminating decimal, or repeating decimals.</u></em>
- A <u>square root that is perfect would be rational</u>. A <u>non-perfect square root is irrational</u>.

Since <em>the square root of 5 is not a perfect square</em>, it would be irrational.

Hope this helps you. I apologize if it’s incorrect.
First find Y
using the Pythagorean theorem
y = sqrt (3^2 -1^2)
y = sqrt(8)
y = 2sqrt(2)
now you can use Y to find Z
Z= sqrt( y^2 + 8^2)
z = 6sqrt(2)
the answer is D
Answer:
$193.20
Step-by-step explanation:
First, find 15% of 168
168* 0.15=25.2
