39 = 1 1/10b
----------
Simplify and flip
39 = 13/10b
13/10b = 39
---------------------
Multiply each side by 10/13
10/13 * 13/10b = 10/13 * 30
b = 30

First make the equation 39=1-((3/10)*b / / - 1-((3/10)*b. Next it should look like (3/10)*b-1+39=0. After that do 3/10*b+38=0//-38. Then do 3/10*b= -38// : 3/10. Your answer after simplifying b= -38/3/10 should be b= -380/3.

PLEASE ANSWER ASAP *picture attached*

Answer:

$x^{2} -2x-8$

Step-by-step explanation:

(f g)(x) is equal to f(x) times g(x). So you just need to multiply both of the equations together. Use the foil method to multiply (x+2)(x-4)

$(fg)(x)=f(x)*g(x)\\\\(fg)(x)=(x+2)(x-4)\\\\(fg)(x)=x^{2} -4x+2x-8\\\\(fg)(x)=x^{2} -2x-8\\$

I have attached an image to better explain the foil method

Can someone please help!! I will give all stars

Verizon [17]

Well we know that sin(angle) = opposite/hypotenuse. using the angle of 38 degrees we see that the opposite is 24 and the hypotenuse is x. So we fill in equation:
sin (38) = 24/x
x *sin (38) = 24
x = 24/ sin (38)
x = 38.98
x = 39.0
