Solve by factoring 3x²-x-4=0

Mathematics
1 answer:
Ivenika [448]3 years ago
3 0

Answer:

( 3x + 1 ) ( x - 1)

Step-by-step explanation:

The given fraction is three 'x' to the power of two that is minus from 'x' minus from four. Simplifying that into three 'x' to the power of two. After this three minus 'x' plus four 'x' minus four. By taking common values which is three 'x' multipled by 'x' and minus one adding the entire by the value four which is further multipled by 'x' and minus one. Finally we obtain our answer that is three 'x' plus one multipled the entire by 'x' and minus one.

3x^2-x-4

3x^2

-3x+4x -4

Take common

3x ( x - 1 ) + 4 ( x - 1 )

( 3x + 1 ) ( x - 1)

Determine if the two triangles are congruent and write the conjecture.<br> pls help
viva [34]

Answer:

(see below)

Step-by-step explanation:

First, to make it easier for yourself, "flip" the triangles so that they "match." To see what I'm talking about, refer to IMAGE.A.

Now that you can tell that the congruent side and angles are corresponding, you have to prove them congruent.

There is one side and two angles, so it's AAS or SAA.

What is the area of a triangle with vertices at (-4,1), (-7,5) and (0,1)
Arlecino [84]

Answer:

62.1467 square units (correct to four decimal places)

Step-by-step explanation:

Let's say the triangle is;

A(-7,5)

B(-4,1)

C(0,1)

Let's say also that AB = a , BC = b  and AC = c

By measurement BC = 4 units , AB = 5 units (applying Pythagorean theorem) and AC = 8.1 units (correct to one decimal place) also through Pythagorean theorem.

Area of this triangle = \sqrt{p(p-a)(p-b)(p-c)} , where p is half the perimeter of the triangle

p = \frac{1}{2}(4 + 8 + 8.1) = 8.55 units

Area = \sqrt{8.55(8.55-5)(8.55-4)(8.55-8.1)} = 62.1467 square units (correct to four decimal places)
