Answer:

(-x - 3) • (x - 1)

Step-by-step explanation:

Step  1  :

           2

Simplify   —

           1

Equation at the end of step  1  :

 ((((x2)+3x)-(2•x2))-5x)+3

Step  2  :

Equation at the end of step  2  :

 ((((x2) +  3x) -  2x2) -  5x) +  3

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  -x2 - 2x + 3  =   -1 • (x2 + 2x - 3)

Trying to factor by splitting the middle term

4.2     Factoring  x2 + 2x - 3

The first term is,  x2  its coefficient is  1 .

The middle term is,  +2x  its coefficient is  2 .

The last term, "the constant", is  -3

Step-1 : Multiply the coefficient of the first term by the constant   1 • -3 = -3

Step-2 : Find two factors of  -3  whose sum equals the coefficient of the middle term, which is   2 .

     -3    +    1    =    -2

     -1    +    3    =    2    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -1  and  3

                    x2 - 1x + 3x - 3

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-1)

             Add up the last 2 terms, pulling out common factors :

                   3 • (x-1)

Step-5 : Add up the four terms of step 4 :

                   (x+3)  •  (x-1)

            Which is the desired factorization

Final result :

 (-x - 3) • (x - 1)

Answer:

-x2 - 8x - 3

Step-by-step explanation:

((((x2)-3x)-(2•x2))-5x)-3

((((x2) -  3x) -  2x2) -  5x) -  3

Pull out like factors :

-x2 - 8x - 3  =   -1 • (x2 + 8x + 3)

Factoring  x2 + 8x + 3

Four loads of stone weigh 2/3 ton. find the weight of 1 load of stone
uranmaximum [27]
4 loads of stone ... 2/3 ton
1 load of stone ... x ton = ?

If you would like to know the weight of 1 load of stone, you can calculate this using the following steps:

4 * x = 2/3 * 1
4 * x = 2/3       /4
x = 2/3 / 4
x = 2/12 = 1/6 ton

The correct result would be 1/6 ton.

Amiraneli [1.4K]

Answer:

A = \pir^{2}

45 = \pir^{2}

45/\pi = r^{2}

14.3 = r^{2}

r = 3.8

ΔXYZ has angles with the following measurements:
k0ka [10]

Answer:

Below in bold.

Step-by-step explanation:

The 3 angles add up to 180 degrees as they are in a triangle.

So 10x - 33 + 4x - 19 + 100 - 2x = 180

12x = 180 + 33 + 19 - 100

12x = 132

x = 11.

So the 3 angles are

10(11) - 33 = 110 - 33 = 77 degrees

4(11) - 19  =  25 degrees

100 - 2(11) = 78 degrees

What is the solution to the system of equations2x + 3y = 40andy=x + 10?
Vladimir79 [104]

Answer:

A is the correct answer

Step-by-step explanation:

If you plug y=x+10 in for the Y variable you just have to solve by multiplying.

1.) It should look like this:

2x + 3(x +10) = 40

2.) You will distribute the three which will make the equation look like this:

2x + 3x + 30 = 40

3.) Add like terms. Then subtract 30 from both sides. Then divide 5 by both sides to get the variable x alone.

Hope that helps
