How do you factor completely x square+5x-6

Mathematics

You find two numbers that add up to the  5  and multiply to the  -6 .

It looks like  6  and  -1  can do the job ...

              adding:           6 + (-1)  =  5
              multiplying:     6 x (-1)  =  -6 .

See ? OK.  So now, the factors of the expression are

     ==>  (x plus one of the numbers)
and
     ==>  (x plus the other number).

           (x + 6) (x - 1)  =  x² + 5x - 6

goldfiish [28.3K]

Answer: 11, 30

Step-by-step explanation:

Given

There were a total of 41 national battlefields and national memorials

Suppose there are x national battlefields

So, national memorials are 3x-3

The sum of the two must be 41

\Rightarrow x+3x-3=41\\\Rightarrow 4x=44\\\Rightarrow x=11

So, there are 11 national battlefields and 3\times 11-3=30 national memorials.

What is true about the dilation?<br> Pre-Image<br> Image
Andrews [41]
A dilation is a transformation that changes the size but not the shape of a figure. Therefore, the image created by the dilation is not congruent to the pre-image, the original figure; it is similar. Each point of the image is distinguished from those of the pre-image by using a prime symbol.

Drag a vertex of the triangle to change its shape.
likoan [24]

Answer:

The correct option is;

45°

Step-by-step explanation:

By angle sum theorem, we have that the sum of angles in a triangle = 180°

Therefore, we have;

When the interior angles of the triangle are constructed to be 60° and 75°, we have by the angle sum theorem;

The third angle + 60° + 75° = 180°

Which gives;

The third angle  = 180°- 60° - 75° = 180°- 135° = 45°

The measurement of the third angle by the angle sum theorem will be 45°

The correct option is ∠third angle = 45°.
