The width of border is 1.5 feet
<h3><u>
Solution:</u></h3>
Given that small garden measures 9 ft by 13 ft
A uniform border around the garden increases the total area to 192 ft square
To find: width of border
Let the width of border be "x"
Then the new measures of garden are (9 + 2x) feet and (13 + 2x) feet
The total area of garden = 192 square feet
<em><u>Let us solve the above equation by quadratic formula</u></em>
Using the above formula,
For , we have a = 4 ; b = 44 ; c = -75
Substituting the values of a = 4 ; b = 44 ; c = -75 in above quadratic formula we get,
Since "x" cannot be negative,
we get x = 1.5
Thus width of border is 1.5 feet
What do you need help with and what subject
Given inequality
=> −2(x+1)≥3x+8
=>
now multiply with - on both sides.
As we know now sign will change
=> 5x >_ -10
Now divide by 5 on both sides
=> x >_ -2
HOPE IT HELPED YOU.
Are you able to expand everything first? from there you would be able to combine line terms. basically if you have 3x+2x it would combine to 5x because they have x in them.
