Step-by-step explanation:
a.) c = 9
To get a perfect square you must divide the bx or 6x in this situation then square it.
6/2 = 3
3^2 = 9
b.) (x - 1)(x - 5)
x^2 - 6x + 9 = -5 + 9
x^2 - 6x + 9 = 4
x^2 - 6x + 9 - 4 = 4 - 4
x^2 - 6x + 5 = 0
(x - 1)(x - 5)
x - 1 = 0
x = 1
x - 5 = 0
x = 5

The angle measures of a triangle are shown in the diagram
what is the value of x?
pls hurry its due soon
Answers
Answer: Subtract the sum of the two angles from 180 degrees. The sum of all the angles of a triangle always equals 180 degrees. Write down the difference you found when subtracting the sum of the two angles from 180 degrees. This is the value of X.
Step-by-step explanation: To find the value of x, bring the variable to the left side and bring all the remaining values to the right side. Simplify the values to find the result.

What is the length of the hypotenuse?
C =
yards
Answers
Answer:
The length of the hypotenuse is 10 yards.
Step-by-step explanation:
Given that this is a right triangle, you could apply the Pythagorean Theorem to it. Although I'm not exactly sure, given as there's no indication in your question.
The Pythagorean Theorem is a^2 + b^2 = c^2, for context.
So, 6^2 + 8^2 = ?^2.
6^2 = 36
8^2 = 64
64 + 36 = 100
However, 100 isn't the side length of c, it's c squared. To "unsquare" it, you need to find the square root of it.
In this case, the square root of 100 is 10.
6^2 + 8^2 = 10^2. Makes sense, right?
36 + 64 = 100
Hope this helps.
There are 4 nickels and 4 dimes in your pocket.You randomly pick a coin out of your pocket and placed it on a counter. Then you randomly pick another coin. The first coin is a nickel and the second coin is a dime. What is the probability
Answers
Answer:
The probability of picking a nickel or a dime is 25%
Step-by-step explanation:
Since we have the same amount of nickels and dimes we can cancel them out. That would make it a 50% chance to get one or the other, or, a 1&1 chance, but since there is 8 coins all together there is a chance to pull out 2 nickels or 2 dimes. 4 possibilities.
1. 1 nickel 1 dime
2. 2 dimes
3. 2 nickels
4. 1 dime 1 nickel
4 x 25% = 100%
each possibility has a 25% chance to happen

Use the diagram below in which P is the incenter of JKL, PN =21 and ML=27 . Find PO, LO, and PL
Answers
Answer:
1. PO = 21
2. LO = 27
3. PL = 34.2
Step-by-step explanation:
1. Since P is the incenter, that means it is equidistant to each side at a right angle. As a result PN, PO, and PM are equal to each other.
We know that PN is 21. Since PN and PO are equal to one another, PO = 21.
2. ML is equal to LO. ML is 27, so LO is also 27.
3. To get PL you will have to do the Pythagorean Theorem. Square the legs and set it equal to the hypotenuse squared.
* It should be: 27^2 + 21^2 = x^2.
Once you solve and round to the nearest tenth, you will get 34.2.

x = 7/10
(substitute x = 7/10 in the ‘x’ spot in either of the two equations)

B. P(K|R) = 0.2
C. P(K|R) = 0.92
D. P(K|R) = 0.08
Answers
Answer:
d. 0.08
Step-by-step explanation:
52 cards in a deck of cards. 26 are red. there are 2 red kings. 2/26= 0.076 which rounds up to 0.08
Half the cards (26) are red
Then there are 2 red kings out of the 26.
Probability of picking a red king out of the red cards is 2/26 = 1/13 = 0.076
Round to 0.08

Marcy purchases a total of 12 adult, child, and senior tickets for an art museum tour. Adult tickets are $5 each, child tickets are $2 each, and senior tickets are $4 each. If she purchases 4 more child tickets than senior tickets and spends a total of $38, which statement is true?
The solution to this system is no viable because it results in fractional values of tickets.
The solution to this system is viable.
The solution to this system is nonviable because it results in negative values of tickets.
The solution to this system is no viable because it results in fractional values of money.
Answers
Answer:
A: The solution to this system is no viable because it results in fractional values of tickets
Step-by-step explanation:
Let number of adult, child, and senior tickets be x, y and z respectively.
Thus;
x + y + z = 12 - - - (eq 1)
she purchases 4 more child tickets than senior tickets.
Thus, y = z + 4
Thus:
x + (z + 4) + z = 12
x + 2z + 4 = 12
x + 2z = 8 - - - (eq 2)
Also, We are told that Adult tickets are $5 each, child tickets are $2 each, and senior tickets are $4 each. She spends a total of $38,
Thus;
5x + 2(z + 4) + 4z = 38
5x + 2z + 8 + 4z = 38
5x + 6z + 8 = 38
5x + 6z = 38 - 8
5x + 6z = 30
Divide through by 5 to get;
x + (6/5)z = 6 - - - (eq 3)
Subtract eq 2 from eq 1 to get;
2z - (6/5)z = 8 - 6
2z - (6/5)z = 2
Multiply through by 5 to get;
10z - 6z = 10
4z = 10
z = 2½
It's not possible to have a fractional value of a ticket and thus we can say that the solution is not viable.
