Answer:
Perimeter of the windows is P = 4s, or (here) P = 4(x+9) ft.
Step-by-step explanation:
If the area of the square is x^2 + 18x + 81 (ft^2), then the length of one side is given by the square root of that, and is x + 9 (ft). Note that (x + 9)^2 = x^2 + 18x + 81.
The perimeter of a square window of side length s is P = 4s.
Here, the perimeter of the square is P = 4(x+9) (ft).
Answer:
1/15 per min
Step-by-step explanation:
3 times 5 equals 15 and so 1/15.
Try making a visual picture to see yourself.
The answer is 16773.6 because you just find the 34.8 percent of 48,200
He ran 4 miles per hour for one hour, which means he ran 4 miles.
He cycled 6 miles at 12 miles per hour, which means he cycled for one half an hour.
His total miles was 4 + 6 = 10 total miles.
His total time was 1 hour + one half an hour = 1.5 hours.
His average speed is total distance divided by total time:
10 / 1.5 = 6 2/3 miles per hour.
Answer:
<h2>x = 29°</h2>
Step-by-step explanation:
From the question the angles lie on a straight line which means that the sum of their angles add up to 180°
Since angles on a straight line add up to 180°
To find the value of x add up all the angles and equate it to 180 to find x
That's
x + 4 + 147 = 180
x + 151 = 180
x = 180 - 151
We have the final answer as
<h3>x = 29°</h3>
Hope this helps you
