I was thinking c but I don’t know
Answer:
Step-by-step explanation:
Yes it is C, u are right
Answer:
C (x + 6)(x + 6)
Step-by-step explanation:
Look for 2 factors of 36 that add up to twelve. 6 and 6 do that, so
[tex]x^{2} + 12x + 36 = (x+6)(x + 6)[/tex]

If 1 is subtracted from a number and this difference is tripled the result is 23 more than the number
Answer:
The number is 13
Step-by-step explanation:
Let the number be y
1 is subtracted from the number. This can be written as:
y – 1
The difference is tripled. This can be written as:
3(y – 1)
The result of the difference tripled is 23 more than the number. This can be written as:
3(y – 1) = 23 + y
Thus, we can obtain the value of y as follow:
3(y – 1) = 23 + y
Clear bracket
3y – 3 = 23 + y
Collect like terms
3y – y = 23 + 3
2y = 26
Divide both side by 2
y = 26 / 2
y = 13
Thus, the number is 13.

Please help! Thanks!
Step-by-step explanation:
Put the what given of y in equation 2 to equation of 1
So you get
[tex] \frac{4}{5} x + \frac{2}{5} x - 7 = - 4 \\ \frac{6}{5} x = 3 \\ x = \frac{15}{6 } \\ x = \frac{5}{2} [/tex]
Then put the value of x in second equation
You will get
[tex]y = - \frac{2}{5} \times \frac{5 }{2} + 7 \\ \\ y = 6[/tex]

Find x for brainliest
Answer:
4
Step-by-step explanation:
6/(6+6) = 5/(5+5) = (3x+5)/(5x+14) = 1/2
3x+5 = 1/2*(5x+14)
6x+10 = 5x+14
x = 4
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 50, 60,72,... Find the 8th term.
Answer:
179.159
Step-by-step explanation:
Given the sequence :
50, 60, 72,..
The sequence given is a geometric sequence :
For a geometric sequence ;
ar^(n - 1)
a = first term
r = a2 / a1 = 60 / 50 = 1.2
The 8th term ; n =8
a8 = ar^(n - 1)
a8 = 50*1.2^(8 - 1)
a8 = 50*1.2^7
a8 = 50*3.5831808
a8 = 179.15904
a8 = 179.159 (nearest thousandth )

Solve for the value of k. (k+8) 400
Answer: The answer to this math question about solving for the value of k with the given full of the angles is k = 6.
Step-by-step explanation: As always to remember, all of the forming angles to a straight line with a sum of 180 degrees, so anyways, here are 6 steps in order to solve for the value of k:
Step 1. First, let's find the measures of the value of all 3 angles, the measures of all 3 angles are, 8°, 90°, and 40° that looks in the equation form like this: [tex]7k + 8 + 90 + 40 = 180.[/tex]
Step 2. Next, after finding the measures of the value of all 3 angles, it's time to add all 3 angles up together that looks in the equation form like this: [tex]7k + 138 = 180.[/tex]
Step 3. Then, let's move positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side that looks in the equation form like this: [tex]7k = 180 - 138.[/tex]
Step 4. In addition to that, after moving positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side, it's time to subtract 138 degrees and 180 degrees that looks in the equation form like this: [tex]7k = 42.[/tex]
Step 5. Now last but not least is finally, after subtracting 138 degrees and 180 degrees, it's time to divide the both sides by 7 that looks in the equation form like this: [tex]\frac{7k}{7}=\frac{42}{7}.[/tex]
Step 6. Hence the value of k is 6.
I hope that my full given answer with my full given step-by-step explanation is very helpful to your own math question about solving for the value of k with the given full of the angles, please mark me as Brainliest, take care, always be safe, and have a great rest of the day and a great weekend! :D

There are 9 flash cards with numbers from 20 to 28 written on them. Laura drew the card with 22 on it. She is about to draw another card. What is the probability that the sum of the numbers on these two cards will be a multiple of 5?
Answer:
1 /4
Step-by-step explanation:
Multiples of 5 = (5, 10, 15, 20, 25, 30, 35, 40, 45)
Numbers on card : (20,21,22,23,24,25,26,27,28)
Number on first card = 22
To have a sum which is a multiple of 5 ; number on second card must be either :
23 or 28
22 + 23 = 45
22 + 28 = 50
Since only 2 of the cards will. Result in a sum which is a multiple of 5
Required outcome = 2
Total possible outcomes = (9 - 1) = 8
Probability = required outcome / Total possible outcomes
= 2 / 8
= 1 /4

You kayak up a river at a rate of 36 feet every 30 seconds. You kayak 304 feet every 2 minutes on the way back down the river. How much farther do you kayak in 5 minutes on the way down the river than in 5 minutes on the way up the river?
Answer:
400 feet
Step-by-step explanation:
on way up you travel 35 ft in 30 sec or 144 ft in 120 sec (2 min)
on way down you travel 304 ft in 120 sec (2 min)
the distance traveled for 5 minutes at rate from way 'up' is 360 feet
the distance traveled for 5 minutes at rate from way 'down' is 760 feet
difference is 400 feet
Answer:
400

shine sold two tables at 9900 rupees each.he got 10% profit in one sale and 10% loss in the other.did the total sale result in a profit or loss? what percentage? please give me step by step explanation
the total sale was neither a profit nor loss , 0%
Step-by-step explanation:
1st table :
100%-> 9900
110%-> 10890
10890-9900=990(earned)
------------------------------------------
2nd table :
100%->9900
90%-> 8910
9900-8910=990(lost)
990-990=0
hence the total sale was neither a profit nor loss , 0%

A police officer gets paid $50 per hour. If she works a holiday, she gets paid time and a half. How much would the officer earn if she worked 7 hours on Christmas day (a holiday)?
a.) $500.00
b.) $525.00
c.) $350.00
Answer:
the correct answer is b $525.00
Step-by-step explanation:
half of her earnings is 25 dollars if she makes time and a half it would be 50 + 25 = $75/hr of overtime (overtime wage)
if she works 7 hours of overtime then... (hours she work) x (overtime wage)
7 x 75 = 525
so her pay would be $525.00
the correct answer would be B

Explanation :
First, you need to convert the mixed numbers into improper fractions. Then, you make sure the denominators are the same. (For example, in the first problem, you have to change the 3/4 to 6/8 to match the 17/8.) Then, you subtract the two fractions, and then turn the resulting improper fraction to a mixed number!
