Bens living room is a rectangle measuring 9 yards by 150 inches. By how many feet does the length of the room exceed the width?

defon

Answer:

14.5 ft or 14 1/2 ft

Step-by-step explanation:

36in= 1 yard

9x36= 324in (I'm guessing this is the length)

324in (length) -150in (width)= 174in

12 in= 1 ft

174/12= 14 ft 6 in

6 inches is half a foot

14.5 ft or 14 1/2 ft

Let p = 5. Enter > , < , or = to compare the expressions. 4p4 2p−3

Y_Kistochka [10]

Answer:

The given expression at p = 5 can be written as:

$4(p^4) > 2p -3$

Step-by-step explanation:

Here, the given expressions are:

$(4p^4 ), (2p-3)$

Now, substitute the value of p = 5 in both the given expressions, we get:

$4(p^4) = 4(5^4) = 4 (625) = 2,500\\\implies 4(p^4) = 2,500$

Similarly,

$(2p-3) = 2(5) - 3 = 10 -3 = 7\\\implies 2p - 3 = 7$

So,now comparing both the values at p = 5, we get:

2,500 > 7

$\implies 4(p^4) > 2p -3$

Hence, the given expression at p = 5 can be written as:

$4(p^4) > 2p -3$
