Answer:Hi,
Let the number be x
Twice the number is 2x
Five less than twice the number is 2x-5, which is given as 9
Therefore, 2x-5 = 9
or, 2x = 9+5
or, 2x = 14
or x=7
Thus the number is 7.

Step-by-step explanation:
(4x^4-1)÷x+1
(256x-1)÷x+1
256-1+1
256
The first step shows the problem
The second step powers 4x 4 times
The third step removes x
The 4th step shows the problem after x is removed.
The 5th step is the answer: 256
Answer: 5.4
--------------------------------------
Explanation:
Angle D = 43 is the given reference angle
side FE = 5 is the side opposite the reference angle (since its the leg furthest away from angle D)
We want to find side DE which is the other leg. This is the adjacent side with angle D as the reference angle
Use the tangent rule
tan(angle) = opposite/adjacent
tan(D) = FE/DE
tan(43) = 5/DE
DE*tan(43) = 5
DE = 5/tan(43)
DE = 5.36184355 <<-- use a calculator here; this is approximate
DE = 5.4 <<-- round to the nearest tenth
That's why 5.4 is the answer
