29. Which of the following expressions will result in a real answer after being simplified? Select all that apply.
A. (4+5i)(4-5i)
B. (4+91)(41-9)
C. (3+2i)(3-2i)
D. (2i+5i) (21-3)
E. (312+7i) (312-7i)
F. (3i2+7i)(312+7i)
Answers
Answer: A, B, C, and E
Step-by-step explanation:
If both sides are real numbers, then the product will be a real number.
If in at least one of the sides we have a complex number, then the product will be real if:
The other number is zero.
The other number is the conjugate of the first.
This is when:
Suppose we have a number:
z = a + b*i
The conjugate will be:
w = a - b*i
And the product between them is:
(a + b*i)*(a - b*i) = a^2 + a*b*i - a*b*i + b^2 = a^2 + b^2
Then the options that will have a real answer are:
A. (4+5i)(4-5i) = 4^2 + 5^2 = 16 + 25 = 41
B. (4 + 91)*(41 - 9) = 3040
C. (3 + 2*i)*(3 -2*i) = 3^2 + 2^2 = 9 + 4 = 13
E. (312 + 7i)*(312 - 7i) = 312^2 + 7^2 = 97,393

A triangular flower bed is to be created. The following figure represents the layout of the flower bed. How many feet of landscape edging would be
required to outline the edge of the bed?
15 ft
17 ft
Answers
Answer:
8 feet
Step-by-step explanation:
The diagram is attached below.
Note that the values are different but the diagram is similar. In this case,
Hypotenuse =17ft
Adjacent = 15²
Required
Opposite side
To get the feet of landscape edging would be required to outline the edge of the bed, we will use the Pythagoras theorem as shown;
Hyp² = Opp²+Adj²
Opp² = Hyp²-Adj²
l² = 17²-15²
l² = 289-225
l² = 64
l = √64
l = 8feet
Hence the feet of landscape edging would be required to outline the edge of the bed is 8 feet

⇒ x = 6
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
⇒ 17x - 23 = (8x - 4) + (3x + 17)
Now,
Solve the expression as;
The expression is,
⇒ 17x - 23 = (8x - 4) + (3x + 17)
⇒ 17x - 23 = 8x - 4 + 3x + 17
⇒ 17x - 23 = 11x + 13
⇒ 17x - 11x = 23 + 13
⇒ 6x = 36
⇒ x = 6
Thus, The value of x will be;
⇒ x = 6

When Lauren left her house in the morning her cell phone battery was partially charged the charge remaining in Lawrence battery as a percentage can be modelled by the equation B equal 63 - 70where T is the number of hours since Lauren left her house what is the X intercept of the equation and what is its interpretation in the context of the problem
Answers
Answer: Intercept of the equation = (9,0)
Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)
Step-by-step explanation:
Given: When t= the number of hours since Lauren left her house, the charge remaining in Lauren's battery, as a percentage, can be modeled by the equation B=63-7t .
To find the x-intercept, put B =0 (as x denoted the independent variable , here independent variable is 't')
Hence, the x-intercept of the equation = (9,0)
i.e. Charge remaining in Lauren's battery is 0 after 9 hours( since Lauren left her house)

A hiker is 345 feet above sea level and a diver is 35 feet below sea level. How far apart are they?
Answers
Answer: 310
Step-by-step explanation:
You would think it’s 380 because 345 + 35 but since it says the diver is BELOW, that means it’s -35 so, -35 + 345, and the 345 stays as a positive number because they’re above the sea level. 345 + -35, hope this helped.
On Saturday, Simone’s volleyball team will be having a family picnic. Hot dogs are sold at the local store with 10 hot dogs in a package. Hot dog buns, however, are only sold in packages of 8 hot dog buns. Simone’s team wants to buy the exact same number of packages for hot dogs as hot dog buns.
What is the least number of packages of hot dogs and hot dog buns that Simone’s team should buy to have exactly the same number of hot dogs as hot dog buns? Show your work.
Answers
Answer:The correct answer is 4 packages of hot dogs and 5 packages of hot dog buns
Explanation:
To find the least number of packages of each item the team has to buy, it is necessary to find the Least Common Multiple of the two numbers (10 and 8), which is the lowest integer that is multiple of both 10 and 8, and therefore represents the least number of hot dogs and hot dog buns the team has to buy to get the same number of the two items. Now, to find the LCM follow this process:
1. List the two numbers
10
8
2. Now, find the multiplies of each number
10 x 1 = 10 / 10 x 2= 20/ 10 x 3= 30 / 10 x 4 = 40...
8 x 1= 8/ 8 x 2 = 16 / 8 x 3 = 24 / 8 x 4 = 32 / 8 x5 = 40...
3. Notice the first common number in both, in this case, 40 because 10 x 4 = 40 and 8 x 5= 40.
This means the Least Common Multiple is 40, and therefore the team should buy 40 of each item. Additionally, this means they need to buy 4 packages of hot dogs (each package contains 10 units) and 5 packages of hot dog buns (each package contains 8 units).
