The common denominator would be 12 because 3*4=12 and 4*3=12

The common denominator would be 12 because 4x3=12 and 3x4=12
In order to find the common denominator, you need to find the least common multiple (LCM).
3:3,6,9,12,15,18,27,24,27
4:4,8,12,16,20,24,28,32, 36
They both have 12 and 24 but we are looking for the LEAST common multiple so it is 12 (since 12 is the first number that 4 and 3 can make together. That is what the LCM is)

#4 I need help on. Thanks! (?)

To find the area you just find the area of each triangle.

To do this use the formula b×h×.5=A

6×4×.5=A

A=12

Now you just multiply 12 by 4. The reason you multiply by 4 is because you have 4 triangles that make up the rhombus. The area of the rhombus is 48cm²

Factor the expression completely over the complex numbers: 25x2 +144

Paha777 [63]

Answer:

25x² + 144 = (5x + 12i) (5x - 12i).

Step-by-step explanation:

We have to factorize the expression 25x² + 144, using the complex number.

Now, $i = \sqrt{- 1}$ can be treated as the complex number as there is negative value with in square root.

So, $i^{2} = - 1$

Therefore, we can write the original expression as

25x² + 144

= 25x² - (i²)(144)

= (5x)² - (12i)²

= (5x + 12i) (5x - 12i)

So, the factorization is 25x² + 144 = (5x + 12i) (5x - 12i). (Answer)

What is the difference of the polynomials [m²n²-7]-(mn+4)

AleksAgata [21]

You can do addition and substraction operations with polynomials similarly as with simple real numbers.

First of all you have to open brackets and then you can add numbers (-7-4=-11). Then the result is following:
$(m^2n^2-7)-(mn+4) =m^2n^2-7-mn-4=m^2n^2-mn-11$

Can anyone explain the basics of solving systems to linear equations?

Len [333]

Answer:

A system of linear equations is just a set of two or more linear equations. In two variables (x and y) , the graph of a system of two equations is a pair of lines in the plane. ... The lines intersect at infinitely many points.

Martin is making squares by arranging 26 sticks. how many squares can he make? Write and solve the number fact you used to find

Alexxx [7]

He could make 6 squares, because each square has 4 sides. And 24 divided by 4 is 6. The number fact that i used is 24 divided by 4
