The height of a trapezoid can be expressed as x – 4, while the bases can be expressed as x + 4 and x + 9. if the area of the tra
AlexFokin [52]

Answer: 19 cm

<u>Step-by-step explanation:</u>

A_{trapezoid}=\frac{b_{1}+b_{2}}{2}*h

                99 = \frac{(x+4 + x+9}{2}*(x - 4)

                99 = \frac{(2x + 13}{2}*(x - 4)

              198 = (2x + 13)(x - 4)

              198 = 2x² + 5x - 52

                 0 = 2x² + 5x - 250

                 0 = 2x²- 20x + 25x - 250

                 0 = 2x(x - 10) + 25( x - 10)

                 0 = (2x + 25)(x - 10)

0 = 2x + 25     or        0 = x - 10

  -\frac{25}{2} = x      or          x = 10

Since length cannot be negative, -\frac{25}{2} can be disregarded

Larger base: x + 9  = 10 + 9   = 19

F<br> (<br> x<br> )<br> =<br> 3<br> x<br> −<br> 12<br> f(x)= <br> 3x−12<br> ​
Nina [5.8K]

The inverse of the given function 3x - 12 is determined as f⁻¹(x) = x/3 + 4.

<h3>What is inverse of a function?</h3>

An inverse of a function is a function that serves to replace another function.

That is, if f(x) produces y, then putting y into the inverse of f produces the 0ut-put x .

Thus, an inverse function or an anti function is defined as a function, which can reverse into another function.

The inverse of the given function; f(x)= 3x − 12 is calculated as follows;

y = 3x - 12

replace y with x and x with y as shown below;

x = 3y - 12

now, solve for y

x + 12 = 3y

divide both sides of the equation by 3

x/3 + 12/3 = 3y/3

x/3 + 4 = y

f⁻¹(x) = x/3 + 4

Thus, the inverse of the given function 3x - 12 is determined as f⁻¹(x) = x/3 + 4.
