\frac{3 +  \frac{x - 3}{9 -  {x}^{2} } }{3 -\frac{4}{x + 3} }  \\  =  \frac{ \frac{3(9 -  {x}^{2} ) + x - 3}{9 -  {x}^{2} } }{ \frac{3(x + 3) - 4}{x + 3} }  \\  =  \frac{27 - 3 {x}^{2}  + x - 3}{9 -  {x}^{2} }  \times  \frac{x + 3}{3x + 12 - 4}  \\  =  \frac{ - 3 {x}^{2} + x + 24 }{ - (x - 3)(x + 3)}  \times  \frac{x + 3}{3x + 8}  \\  =   \frac{ - (3x + 8)(x - 3)}{ - (x - 3)}  \times  \frac{1}{3x + 8}  \\  =   \frac{ - (x - 3)}{ - (x - 3)}  \\  = 1

<h3>What are ratio and proportion?</h3>

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A kicker made 10 of his last 12 field goals.

Predict the number of his next 42 field goals the kicker will not make will be

Let x be the number of his next 42 field goals the kicker will not make.

Then we have

x / 10 ≠ 42 / 12

      x ≠ 35

More about the ratio and the proportion link is given below.

Answer:

7.) 53.38

8.) 18.84

9.) 87.92

Step-by-step explanation:

7.)

For the first question, we can see that the diameter is given. So, we will want to divide that diameter by 2 to get the radius. 17 ÷ 2 = 8.5.

The formula for finding the circumference is 2 × π × 8.5

2 × 3.14(π) = 6.28.

6.28 × 8.5 = 53.38

8.)

For the second question, we can see that the radius is now given to us which is 3ft.

The formula for finding the circumference is 2 × π × 3

2 × 3.14(π) = 6.28.

6.28 × 3 = 18.84

9.)

For the third question the raduis is also given to us, which is 14 in.

The formula for finding the circumference is 2 × π × 14.

2 × 3.14(π) = 6.28.

6.28 × 14 = 87.92

How do you simplify 7 (2x+10) thanks in advance

The only thing you should do is to multiply 7 by 2x and 10. 
so you will have: (7*2x) + (7*10) = 14x + 70 :)))
