Answer:
16a^2+16a-5
Step-by-step explanation:
set the equations up as a binomial and use FOIL to distribute then add like terms:
(4a+5)(4a-1)
=16a^2-4a+20a-5
=16a^2+16a-5
Given right triangle ABCABC with altitude \overline{BD} BD drawn to hypotenuse ACAC. If AD=3AD=3 and AC=12,AC=12, what is the length of \overline{AB}? AB ? (Note: the figure is not drawn to scale.)
Answer:
The answer is "6"
Step-by-step explanation:
[tex]\to x^2 = 3 \times 12 \\\\\to \sqrt{6^2 +3^2} = \sqrt{45} =\sqrt{9} \sqrt{5} = 3\sqrt{5} \\\\\to x= 6[/tex]
The value of [tex]\overline{AB} =6[/tex]
Write 24 as a product of primes.
Use index notation when giving your answer.
Answer:
2^3 * 3
Step-by-step explanation:
Here are the first several prime numbers: 2, 3, 5, 7, 11, 13, 17, 19, 23
To find the prime factorization of a number, start by dividing the number by the smallest prime number it is divisible by. Keep dividing by that prime number until you can't anymore. You only divide by prime numbers that divide evenly. Then move on to the next prime number that divides evenly, and do the same. You eventually will get to 1. Then you put together all the prime factors.
This is much easier to do than it sounds like in this explanation.
Start with 24.
24/2 = 12
12/2 = 6
6/2 = 3 3 is not divisible by 2, so we move on to 3.
3/3 = 1 We got to 1, so we are done.
The prime factorization is the product of all the prime numbers we divided by which are in bold.
24 = 2 * 2 * 2 * 3
Now we index it:
24 = 2^3 * 3

2. When 9 is added to the number that is produced by tripling the number x, the result is
equal to 6 times the number that is 3 less than x. Write an equation to represent the
situation and use it to find the value of x.
The equation that represents the situation is:
9 + 3x = 6(x - 3)
The value of x is x = 9
Word problem on linear equationLet the number be represented by x
Triple the number = 3x
9 added to the number that is produced by tripling the number x = 9 + 3x
3 less than x = x - 3
6 times the number that is 3 less than x = 6(x - 3)
Therefore, the equation that illustrates the situation is:
9 + 3x = 6(x - 3)
Solve for x in the equation above
9 + 3x = 6x - 18
6x - 3x = 9 + 18
3x = 27
Divide both sides by 3
3x/3 = 27/3
x = 9

There are 2.54 cm in 1 inch. they are 100 cm in 1 m, to the nearest meter, how many meters are in 474 inches
Multiply total meters by 100 to get total centimeters:
6 meters x 100 = 600 centimeters.
Now divide total centimeters by 2.554 to get total inches:
600 centimeters / 2.54 = 236.22 inches.
Rounded to the nearest inch = 236 inches.

Garden soil costs $5.00 per a 2 cubic foot bag at lows. You have raised rectangular garden thag is 8 feet by 4 feet and you wish the depth of the soil to be 6 inches deep. How much will it cost to buy the bags of soul for your garden
Answer:
$40
Step-by-step explanation:
Step one:
given data
Garden soil costs $5.00 per a 2 cubic foot bag
dimension of rectangular garden raised
8 feet by 4 feet , depth is 6 in
6 in to feet= 0.5ft
the volume of the soil in the garden is
volume= 8*4*0.5= 16ft^3
Step two:
now if 2ft^3 cost $5
16ft^3 will cost x
cross multiply
x*2=16*5
divide both sides by 2
x= 16*5/2
x=80/2
x=$40

The access code to a houses security system consists of 6 digits. How many different codes are available if each digit can be repeated? Please show work.
Answer:
1,000,000
Step-by-step explanation: Since there are 10 possible digits, we know that there is a 1/10 chance for any possible digit in any slot. So, since there are 6 slots we can do 1/10^6, or 1 in 1 million.
So, 720 ways are available if each digit can be repeated
Combination:A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order.

CJ wants a new video game but is not sure which one to buy. His choices are 5 sports games, 3 role-playing games, and 8 action games. He writes the game titles on pieces of paper and puts them all in a bag. He wants to buy two different games. If he randomly selects two names from the bag, what is the probability that CJ selects two sports games?
Answer:
1 /12
Step-by-step explanation:
Given that:
Number of sports game = 5
Role playing games = 3
Action games = 8
Total = (5 + 3 + 8) = 16
The probability of selecting two sports game from the bag :
First selection = sport game and second selection will also be a sport game.
This scenario with be a selection without replacement pattern
First selection :
Number of sports game / total number of options
5 / 16
SEcond selection : total left = 16 - 1 = 15 ; number of sports game = 5 - 1 = 4
Hence
P(sports on second selection) = 4 / 15
P(sports on first and second) :
5/ 16 * 4/15 = 20/ 240 = 1 / 12

The Video Club charges a $100 membership fee and then charges $5 per movie. The Movie Market has a $25 membership fee and then charges $10 per movie. When will both clubs have the same cost? What is the cost?
Answer:
At 15 movies, both will cost $175
Step-by-step explanation:
Set it up algebraicly. Let x be the number of movies
100 + 5x = 25 + 10x
75 + 5x = 10x
75 = 5x
x = 15
Lets substitute x into one equation
100 + 5(15)
100+75
175
