Answer: 7

Step-by-step explanation:

As tangents drawn from a common external point to a circle are congruent,

8x - 7 = 6x + 7
2x - 7 = 7 [subtract 2x from both sides]
2x = 14 [add 7 to both sides]
x = 7 [divide both sides by 2]

Write a quadratic function f(x) for the area of a rectangle length x+5 width 3x-7

Semmy [17]

The area of a rectangle is the product of its length and width.
$l=x+5 \\
w=3x-7 \\ \\
A=lw=(x+5)(3x-7)=3x^2-7x+15x-35=3x^2+8x-35 \\ \\
\boxed{f(x)=3x^2+8x-35}$
