Help please..! I need the answer to this thank you.
torisob [31]

1. The additive identity is 0. This is because adding 0 to anything leads to the same value. Example: 0+3 = 3.

2. An equation is where you have two expressions separated by an equal sign. In your case it would be "a mathematical sentence whose verb is 'equal' (=)"

3. The multiplicative identity is 1. Multiply 1 with any number and the result is that same number. Example: 1*7 = 7.

4. An open sentence is an equation that contains one or more variables. An example would be x+2 = 4. The reason why we call it open is because the true or false nature of the sentence is up in the air until we know what x is. If we knew that x = 3 for instance, then x+2 = 4 would be false since 3+2 = 4 is false. If we nailed down what x was then it would go from open to closed.

5. The symmetric property is that if a = b then b = a. Think of a mirror how the image reverses.

Given the kite below, if NO = 5 and OM = 12, what is the value of NM?
tester [92]

Answer:

NM = 13

Step-by-step explanation:

pythagorean theorem: a^{2} + b^{2} = c^{2}

a or NO = 5

b or OM = 12

c or NM = ?

plug in what is known:

⇒ 5^{2} + 12^{2} = c^{2}

⇒ 25 + 144 = c^{2}

⇒ 169 = c^{2}

square root each side of the equation:

⇒ \sqrt{169} = \sqrt{c^{2} }

solve:

⇒ 13 = c
