How would get the area?
yuradex [85]

Answer:

x > 5

Step-by-step explanation:

Formula: length x width

First, you must substitute in the numbers.

16-2x*10 < 60

Work:

(16-2x)10 < 60

Then, distribute the 10 to the 16 and to the 2x.

160-20x < 60

Next, substract 160 from both sides.

-20x < -100

Now, divide -20 from both sides.

x < 5

This isn't the answer yet because you have to flip the sign because you divided by a negative.

x > 5

Given the function f ( x ) = x^2 + 7 x + 10/ x^2 + 9 x + 20 Describe where the function has a hole and how you found your answer
ryzh [129]

{x}^{2}  + 7x +  \frac{10}{ {x}^{2} }  + 9x + 20 \\  =  {x}^{2}  + 16x +  \frac{10}{ {x}^{2} }  + 20 \\ x = 0 \\  \frac{10}{ {x}^{2} }  =  \frac{10}{0}

= undefined

It is undefined as you cannot divide by zero. Hence, there is a hole at x = 0.
