The answer is 0 < x ≤ 7

First, we know that width = x
Which means that length = x +18

So, the possible equation for the Table's area is

X (X + 18) ≤ 175

X^2 + 18x - 175 ≤ 0

Next, we need to calculate is by using complete square method
x^2 + 18x + 81 ≤ 175 + 81

(x + 9)^2 ≤ 256

|x + 9| ≤ sqrt(256)

|x + 9| ≤ +-16

-16 ≤ x + 9 ≤ 16

-16 - 9 ≤ x ≤ 16 - 9

-25 ≤ x ≤ 7

Since the width couldn't be negative, we can change -25 with 0,

so it become
 0 < x ≤ 7

Find the unit rate. 180 miles in 3 hours

leva [86]

Answer:

60 miles per hour

Step-by-step explanation:

First, put the equation in a fraction.

You would put 180 up top because people always say miles per hour not the other way around.

You can see the dividing line as your "per" and your "hour" would be the bottom number.

To find the unit rate, you will divide the numerator (180) and the denominator (3).

Your final answer should be 60 miles per hour.

$\frac{180}{3} = \frac{60}{1}= 60$
