Solve the system using elimination 3x+2y=17 and 2x+5y=26
Arte-miy333 [17]

Answer:

3x + 2y = 17

2x + 5 y = 26

Step-by-step explanation:

3x + 2y = 17 }

2x + 5 y = 26}

x - 3y = - 9

x = -9 + 3y

=> 2 (-9+3y)+5y=26

-18+6y+5y=26

-18+11y=26

11y=26+18

11y=44

y= 4

3x + 8=17

3x = 17 - 8

3x = 9

x = 9 : 3

x = 3

Can someone help me with factoring? 4x^3 + 43x^2 + 30x
Sergio039 [100]
4x^{3}+43x^2+30x
First in factoring, you must find out what is common in the whole equation
x(4x^2+43x+30)
Now, make 2 sets of parentheses and "split up" the rest of the equation
Try to experiment which numbers work out
We are not subtracting anything so both parentheses are positive
x(4x+3)(x+10)
Therefore, the factored version of 4x^3+43^2+30x is
x(4x+3)(x+10)

PLS HELP I WILL GIVE BRAINLIEST
mr_godi [17]

Answer:

21 square feet

Step-by-step explanation:

To find out the area of this irregular figure, divide it into two rectangles and add their areas.. This can be done in two ways.

Version 1: 6 * 2 rectangle and 3 * 3 square

(6 * 2) + (3 * 3)

12 + 9

21 sq. ft.

Version 2: 5 * 3 rectangle + 2 * 3 rectangle

(5 * 3) + (2 * 3)

<em>You could really just do 7 * 3 here.</em>

7 * 3

21 sq. ft.

Either way, you still get 21 square feet as your answer.
