Which equation demonstrates the additive identity property?
0 (7+4i)+(7-4i) = 14
O (7+4i)+ 1 = 7+4i
(7+4)(1) = 7+4)
O (7+4i)+(-7-4i)= 0
Answer:
A
Step-by-step explanation:
The Explication 0 (7+4i)+(7-4i) = 14
The correct equation which demonstrates the additive identity property is,
⇒ (7 + 4i) + 0 = 7 + 4i
What is Addition?The process of combining two or more numbers is called the Addition. The 4 main properties of addition are commutative, associative, distributive, and additive identity.
Now, If we add a real number to zero or add zero to a real number, then we get the same real number back.
Hence, The number zero is known as the identity element, or the additive identity.
For example: a + 0 = a
Hence, we can see that;
⇒ (7 + 4i) + 0 = 7 + 4i
Since, 0 is the additive identity here.
Thus, The correct equation which demonstrates the additive identity property is,
⇒ (7 + 4i) + 0 = 7 + 4i

Answer:
69.9 (nice)
Step-by-step explanation:
To solve this, use the order of operations: PEMDAS (Parenthasis, exponents, Multiplication/Division, Addition/subtraction) In order.
1. Solve in the parenthasis, (2+3³). 3³ = 27, so 2+27 is 29. Plug in 29 to the equation: 5³-29×1.9
2. Next is exponents. 5³ has an exponent, which equals 125. Now you plug that into the equation to be 125-29×1.9
3. Now comes multiplication/division. In this case, it's multiplication. -29×1.9 . This equals -55.1, and you once again plug this into the equation to simplify which gives you 125 - 55.1
4. Last in the order of PEMDAS is addition/subtraction. The final simplification of the equation is 125 - 55.1 which is subtraction and this equals 69.9 (nice)
So in conclusion, your answer is 69.9 (nice)

The perimeter of the elliptical table is given by the path traced with the
string attached to the foci of the ellipse.
The distance between the two thumbtacks is 2·√(5)Reasons:
The shape of the table top = An ellipse
The dimensions of the plywood = 4 foot by 6 foot
Required:
The distance between the thumbtacks of the largest possible ellipse
Solution:
The major axis of the largest possible axis = 6 foot
The minor axis of the ellipse = 4 foot
[tex]The \ semi \ major \ axis, \ a = \dfrac{6}{2} = 3[/tex]
[tex]The \ semi \ minor \ axis, \ b = \dfrac{4}{2} = 2[/tex]
Which gives;
The focus, c² = a² - b²
Therefore;
c² = 3² - 2² = 5
c = √(5)
The distance between the two thumbtacks = c - (-c) = c + c = 2·c
Therefore;
The distance between the two thumbtacks = 2·√(5)

-18 = 3 (-z + 6) + 2z
Answer:
z = 36
Step-by-step explanation:
1) Distribute
-18 = -3z + 18 + 2z
2) Combine like terms
-18 = -z + 18
3) Subtract 18 from both sides of the equation
-18 - 18 = -z + 18 - 18
4) Simplify
a. Subtract the numbers
-36 = -z + 18 - 18
b. Subtract the numbers
-36 = z
5) Divide both sides of the equation by the same term
-36/ - 1 = -z/-1
6) Simplify
a. Divide the numbers
36 = -z/-1
b. Cancel terms that are in both the numerator and denominator
36 = z
c. Move the variable to the left
z = 36
