78%
14/18 is 77.78%
Rounded to the nearest percent is 78%
Hope this helps!
SOLUTION:
Let whole number = x
x + 2x^2 = 21
2x^2 + x - 21 = 0
2x^2 + 7x - 6x - 21 = 0
x ( 2x + 7 ) - 3 ( 2x + 7 ) = 0
( 2x + 7 ) ( x - 3 ) = 0
2x + 7 = 0
2x = - 7
x = - 7 / 2
OR
x - 3 = 0
x = 3
ANSWER:
Therefore, as 3 is a whole number while - 7 / 2 isn't a whole number, the whole number must be 3.
Hope this helps! :)
Have a lovely day! <3
Answer:
Step-by-step explanation:
,,,
F(x + 1) =
3(x+1) +2 =
3x + 3 + 2 =
3x +5
step 1: insert x+1 in place of x in the equation
step 2: distribute 3 to x and 1
step 3: combine like terms
