Answer:
-3 2 6
Step-by-step explanation:
Consider this expression.
-3x2- 24x - 36
What expression is equivalent to the given expression?
-3 (x + 2)(x+6)
Drop down answer is in bold
The equivalent expression will be : - 3 (x + 2) (x + 6)
We have the following expression -
[tex]-3x^{2}[/tex] - 24x - 36
We have to find out the equivalent expression of above expression.
Expand the following expression - (x + 2)(x + 4).Above expression can be expanded in the following way -
(x + 2)(x + 4) = x(x + 2) + 4(x + 4) = [tex]x^{2}[/tex] + 2x + 4x + 16 = [tex]x^{2}[/tex] + 2x + 16
According to question -
[tex]-3x^{2}[/tex] - 24x - 36
- 3 ([tex]x^{2}[/tex] + 8x + 12)
-3 ([tex]x^{2}[/tex] + 6x + 2x + 12)
-3 [x(x + 6) + 2(x + 6)]
-3(x + 2)(x + 6)
Hence, the equivalent expression will be : -3(x + 2)(x + 6)

Answer:
1 banana = 0.25
Step-by-step explanation:
Find the proportion. Simply divide the cost from the amount of bananas given:
0.50/2 = 0.25
1.00/4 = 0.25
1.50/6 = 0.25
$0.25 is the cost per banana, and is your proportion.

Answer:
1 banana = + $0.25
2 bananas = + $0.50
Step-by-step explanation:
If it is increasing %0.50 for every 2 bananas then that also means it's increasing $0.25 for every 1 banana.

What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

Step-by-step explanation:
Hello!!!
I can understand how you feel about this. I hope to do my best in helping you understand quadrant numbering and signs.
Now for the number start form the top right and move counter-clockwise, that is
Top right =1st quadrant
Top left = 2nd quadrant
Bottom left = 3rd quadrant
Bottom right =4th quadrant
Basically moving counter-clockwise you will get this
Now for the sign convection
Up and right are both positive
Down and left are both negative.

write 843 in scientific notation.
a x 10b
Follow the steps below to see how 843 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 843New Number: 8.43Step 2
Now, to find b, count how many places to the right of the decimal.
New Number:8.43Decimal Count:12
There are 2 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 8.43
b = 2
Now the whole thing:
8.43 x 102
Step 4
Check your work:
102 = 100 x 8.43 = 843

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirrels. The total number of animals she caught is ten more than four times the number of deer caught. How many rabbits did Katniss catch? Help steps
Answer:
10 rabbits
Step-by-step explanation:
Let us represent
Number of rabbits = x
Number of squirrels = y
Number of deer = z
Katniss caught three times as many squirrels as deer.
y = 3z
She also caught five less rabbits than squirrels.
y = x - 5
The total number of animals she caught is ten more than four times the number of deer caught.
x + y + z = 4 × z + 10
x + y + z = 4z + 10
How many rabbits did Katniss catch?
Number of rabbits = x
We make x subject of the formula
x + y + z = 4z + 10
x = 4z + 10 - y - z
y = 3z
x = 4z + 10 - 3z - z
x = 4z - z - 3z + 10
x = 4z - 4z + 10
x = 0 + 10
x = 10
Therefore, the number of rabbits Katniss caught is 10 rabbits

between which two consecutive integers does the negative square root of 20 lie
Janet bought same bars of choclate to share equally with her friends. she bought between 35 and 50 bars altogether. if she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over. If she shares the bars equally with 6 friends she will have 5 bars left over. How many bars of chocolate did she buy?
a.47
b.45
c.46
d.48
For the conditions to be fulfilled number of chocolate bars Janet bought is 35.
What is an equation?An equation is a statement in form of numbers and variables that both sides are equal.
Janet bought the same bars of chocolate to share equally with her friends and it is between 36 and 50.
There are two possible cases,
Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'A'.
(i) If she shares the bars of chocolate equally with 7 friends, she will have 7 bars left over,
∴ N = 7A + 7...(i).
(ii) If she shares the bars equally with 6 friends she will have 5 bars left over,
Let the number of chocolates be 'N' and no. of chocolates each friend gets be 'B'.
∴ N = 6B + 5...(ii)
Now, we have to equate these two equations,
7A + 7 = 6B + 5.
7A = 6B - 2.
A = (6B - 2)/7.
From here we have to find such integer value of B which also makes the value of A an integer and also when we put the values of either A or B in our equations it should lie between 35 and 50.
So,
A = (6B - 2)/7.
When B = 5 then A = 4. Or when B = 12 the A = 10.
But the B = 12 and A = 10 is inadmissible.
Now, we'll put the value of A or B in eqn (i) or (ii).
Which results in N = 35.
So, the number of chocolate bars she bought is 35.
