Elimination is where you aline two equations with the varibles in the same place and the second equation substracts the first equation. Important to know that in the second equation all varibles and constant or y - intercepts are negative. Now with this just start with the first two equations, 5x + 2y -3z = 10 and 2x - 2y + 4z = 6.

5x + 2y - 3z = 10

- 2x + 2y - 4z = -6

3x + 4y - 7z = 4

Do the same thing with the last equation.

3x + 4y - 7z = 4

-x + y - 2z = -3

2x + 5y -9z = 1

Please tell me if I got it wrong, but from what I concluded there's no solution.

What is s squared +2x-35 factor
Evgen [1.6K]
X^2 + 2x - 35

(a x b) = -35
(a + b) = 2

(7 x -5) = -35
(7 + -5) = 2

Plug them in: 

x^2 - 5x + 7x -35
x(x - 5) + 7(x - 5)

Therefore, you can conclude that our final answer is...

(x + 7)(x - 5)

If you have any questions or do not understand, comment below my answer. :)

The area of a door is 3024 square inches. If
olasank [31]

Answer:

Lets take all factors into consideration first

The door is a rectangle and the area of a rectangle is length times width

Let the width be w

Let the length be l

Equation length × breadth = area

(w+48)w = 3024

w^2 + 48w = 3024

w^2 + 48w - 3024 = 0

w^2 + 84w - 36w - 3024 = 0

w(w + 84) -36 ( w + 84) = 0

(w + 84) (w - 36) = 0

w + 84 = 0 AND w - 36 =0

w = -84 and w = 36

Since width cannot be negative, the right answer is 36

How did I get 84 and 36? Well, I had to factorize 3024 and since 84 times 36 is 3024 and 84 minus 36 is 48, I chose them.
