The quadratic equation (3k-2)x^2 +12x+3(k+1) =0 has equal roots. Find the two possible values of k.
romanna [79]
x_1=x_2 \Rightarrow \Delta=0\\
\Delta=12^2-4\cdot(3k-2)\cdot3(k+1)\\
\Delta=144-(36k-24)(k+1)\\
\Delta=144-36k^2-36k+24k+24\\
\Delta=-36k^2-12k+168\\
-36k^2-12k+168=0\\
-3k^2-k+14=0\\
-3k^2+6k-7k+14=0\\
-3k(k-2)-7(k-2)=0\\
-(3k+7)(k-2)=0\\
k=-\frac{7}{3} \vee k=2

Sara covers the top of a box with squares of paper that are 1 square centimeter: she uses 48 squares with 6 squares in each row.
scZoUnD [109]

Answer:

Sarah makes 8 rows of squares.

Step-by-step explanation:

Given:

Number of squares she uses = 48

Number of squares in each row = 6

We need to find the number of rows she can makes.

Solution:

Let the number of rows she can make be 'x'.

Now we can say that;

Number of rows she can make is equal to Number of squares she uses divided by number of squares in each row.

framing in equation form we get;

x=\frac{48}{6}=8\ rows

Hence Sarah makes 8 rows of squares.

What does the m in 4m-4=4m mean
Hoochie [10]
Hello there ^ _ ^

When you have 4m - 4 = 4m
The m means that you are looking for a number, but the number is unknown and you usually need to find it.

M is like blank space.
For example : She .... two apples
The blank space can be eats. right?

well it is the same thing for M
4..-4 = 4..
The blank space is missing a letter and you need to go look for that letter or number.

Now, let me solve it for you just in case if you would like to know how to find that unknown number.

4m - 4 = 4m
You need to put the common terms together ( the common terms are the one that looks alike)
we have two 4m, right ? so we gonna put them together.
-4 = 4m - 4m
-4 = 0
Add 4 to both sides
-4+4 = 0+4
0 = 4
In this case there are no solutions.

This mean that there no number you can replace m with that will make them equal. Does that make sense ?

I hope this help! Comment if you have more questions!
