For this case we have that by definition, the area of a rectangle is given by:
Where:
w: Is the width of the rectangle
l: is the length of the rectangle
According to the data of the statement we have:
So, the length is given by:
We factor the numerator:
We simplify:
So, the length is 
Answer:
This is the concept of algebra, we are required to find a number,x, such that 87 decreased by three times a number is great than one hundred and sixty-five.
Supposed the number is x, three times the number will be:
3*x=3x
thus;
87-3x≥165
-3x≥165-87
-3x≥78
dividing both sides by -3 we get:
(-3x)/(-3x)≥78/(-3)
x≤-26
This implies that the number is less than or equal to 26
Answer:
40,550
Step-by-step explanation:
40, 550 is the mod point
-- The trains start moving at the same time.
-- The space between them is initially 252.5 miles.
-- They reduce the distance between them at the rate of (124.7+253.5)=378.2mph.
-- It will take them (252.5 / 378.2) = 0.6676 hour to meet.
That's 40min 3.49sec .
-- After tooting and puffing toward each other for 8 minutes, they still have <em>32min 3.49sec</em> to go before they meet each other. We're all hoping that they're on different tracks.
Answer:
10 cm
Step-by-step explanation:
a^2 + b^2 =c^2
6^2 + 8^2 = c^2
36 + 64 = 100
then find the square root of 100 which equals 10
