Answer:
x=6 because 6x13 =78
Step-by-step explanation:
do u have to use the exact same number for all the substitutions?
Let width be x
Length: 2x-3
44=(x)(2x-3)
44=2x²-3x
0=2x²-3x-44
0=(2x-11)(x+4)
x=+11/2 or x=-4
Since dimensions cannot be negative, we have to use 11/2 or 5.5
The Width is 5.5ft , length is (2(5.5)-3)=8 ft
Hope I helped :)
Answer:
2^x+3= 2^2(x-2)
Step-by-step explanation:
as 4 can be written as 2^2
2^x+3= 2^2(x-2)
so 2^x+3= 2^2x-4 is the answer..
In this question the main trick lies in the fact that Umesh is getting paid at the rate of 75 cents per kilometer. It has to be converted to dollars for getting to the correct answer. Now let us get down to the problem in hand
75 cents = 0.75 dollars
Then
For 1 kilometer of travel Umesh gets paid = 0.75 dollars
So
For 120 kilometers of travel in a day, Umesh will get paid = 120 * 0.75 dollars
= 90 dollars
From the above deduction we can easily conclude that the travel allowance for Umesh for the day will be $90. I hope this has helped you.
