Factor the four term polynomial by grouping.<br>10x^3-15x^2+6x-9​
goldfiish [28.3K]

Answer:

(5x²  + 3) (2x-3)

Step-by-step explanation:

10x³ - 15x² + 6x - 9   (rearrange)

10x³+ 6x - 15x²  - 9  (group using parentheses)

(10x³+ 6x) - (15x²  + 9)  (factor out 2x from first term and 3 from second term)

2x (5x²+ 3) - 3(5x²  + 3)   (factor out (5x²+3) )

(5x²  + 3) (2x-3)  (answer)

Lena [83]

Answer: D

Step-by-step explanation:

To find the perimeter of the square, you want to first find the length of each side. Since the figure is a square, we know that each side is equal to each other. We can set the expressions equal to each other to find x.

\frac{3}{4}x-1=\frac{1}{2}x+7           [subtract both sides by 1/2x]

\frac{1}{4}x-1=7                    [add both sides by 1]

\frac{1}{4}x=8                           [multiply both sides by 4]

x=32

Now that we know x, we can plug it into each expression to find teh length of each side.

\frac{3}{4}(32)-1                       [multiply]

24-1                           [subtract]

23

Now that we know each side is equal to 23, we can add all the sides together to find the perimeter.

23+23+23+23=92        or          23×4=92

Since we know that the perimeter is 92 units, the answer is D.

I need help on number 2. A

You should use a protractor to help you with this answer; without one it's really hard to draw a 62 degree angle on your own. Sorry!!!

Can someone please explain how I would figure this out
skad [1K]
[1], [3] => a = 49,000/2 = 24,500 => b +c = 24,500 => c = 24,500 - b;
[2] => 25*24,500 + 20b + 15c = 1,052,000 => 20b + 15c = 1,027,500;
20b + 15*(24,500 - b) = 1,027,500 => 5b = 733,500 => b = 146,700 =>
c = - 122,200;
