love history [14]

Answer:

12

Step-by-step explanation:

Well, I am pretty sure you are looking for the length.

Since area = length x width, I would say that you could divide as well.

120 = 10 x 12

I am pretty sure the length is 12.

If sin(2x + 7)degrees =cos(4x-7)degrees, what is the value of x?

nikklg [1K]

Answer:

x = 15

Step-by-step explanation:

$cosx = sin(\frac{\pi}{2} - x)$

$sin x = sin y = > x = sin^{-1}(sin y) = y => x = y$

$sin(2x + 7)^{\circ} = cos(4x - 7)^{\circ}\\\\sin(2x + 7)^{\circ} = sin(\frac{\pi}{2} - (4x - 7))\\\\(2x + 7) = (\frac{\pi}{2}- (4x -7))\\\\2x + 7 = \frac{\pi}{2} - 4x + 7\\\\6x = \frac{\pi}{2}\\\\x = \frac{\pi}{12}$

x = 15

Solve the equation by completing the square. Round to the nearest hundredth if necessary. x^2+2x=17

Dahasolnce [82]

We have that
x²+2x=17
Group terms that contain the same variable
(x²+2x)=17
Complete the square. Remember to balance the equation
(x²+2x+1)=17+1

Rewrite as perfect squares

(x+1)²=18

x+1=(+/-)√18

x=(+/-)√18-1

x1=√18-1----> 3.24

x2=-√18-1----> -5.24

the answer is

the option

4.) 3.24, –5.24
