Answer: C. \frac{x-3}{3x+1}

Step-by-step explanation:

\frac{x+2}{x^2+5x+6} ÷ \frac{3x+1}{x^2-9} =

\frac{x+2}{x^2+5x+6} * \frac{x^2-9}{3x+1} = \frac{x+2}{(x+3)(x+2)} * \frac{(x-3)(x+3)}{3x+1} =

multiply and cancel out same terms / simplify

first x+3 and x+3 cancel out

then x+2/x+2 cancels out to make 1

\frac{x+2}{(x+2)} * \frac{(x-3)}{3x+1} = \frac{x-3}{3x+1}

The isosceles trapezoid ABDE is part of an isosceles triangle ACE. Find the measure of the vertex angle of ACE
tensa zangetsu [6.8K]
You can solve this problem by folllowing the steps below:
 
  1. Draw a segment from the point C to the line AE, as you can see in the figure attached.
 2. You have now two equal right trapezoids, then: m∠ABG=m∠EDG.
 3. m∠ACE=m∠EDG
 3. The sum of the interior angles of the trapezoid is 360º.
 4. Then, you have:
 
 m∠EDG+m∠D+m∠G+m∠F=360º
 
 m∠D=115º
 m∠G=90º
 m∠F=90º
 
 5. When you clear m∠EDG, you obtain:
 
 m∠EDG=360º-m∠D-m∠G-m∠F
 m∠EDG=360º-115º-90º-90º
 m∠EDG=65º
 
 6. Therefore:
 
 m∠ACE=m∠EDG
 m∠ACE=65º
 
 The answer is: C.65º

Step-by-step explanation:

n(h)=36h because there are 3 dozen cupcakes made per hour, to get C(h) you just plug in 36h in place of n and simplify, and then for the final answer 2 is plugged into the equation from the second answer.

What is the value of f(x) = 2 • 2^x for f(–2)? Will Give brainliest answer!!!
Sedbober [7]
For f(-2), x will equal -2.

Plug the x-value into the equation:

2 \times 2^{-2}

A negative exponent means that the term turns into a fraction, with 1 as the numerator and the positive exponent as the denominator. 
Solve 2^(-2):

2^{-2} =  \frac{1}{2^{2}} =  \frac{1}{4}

Solve the problem:

2 \times \frac{1}{4} = \frac{1}{2}

f(-2) will equal 1/2.
