Answer:
49
Step-by-step explanation:
The expression is given below:
x^2 + 14x
Let y be the constant that will make the expression a perfect square. Therefore, the expression can be written as:
x^2 + 14x + y
Applying the formula b^2 = 4ac, we can easily obtain the value of y as shown below:
x^2 + 14x + y
Coefficient of x^2 (a) = 1
Coefficient of x (b) = 14
Constant (c) = y
b^2 = 4ac
14^2 = 4 x 1 x c
196 = 4c
Divide both side by the coefficient of c i.e 4
c = 196/4
c = 49
Thus, 49 must be added to the expression to make it a perfect square.
y=2x+5
2(2x+5)+4x=10
4x+10+4x=10
8x=20
So there's one solution, x=2.5

Answer:
The number is 10
Step-by-step explanation:
Let the number be x.
four thirds times = 4/3
According to the statement:
four thrids times the sum of a number and 8 is 24
4/3 *(x+8)= 24
Move 3 to the R.H.S and Multiply 4 with the parenthesis.
4x+32=24*3
4x+32=72
Move constant to the R.H.S
4x=72-32
4x=40
Divide both the terms by 4
4x/4=40/4
x=10
Therefore the number is 10....
Answer:7350
The total arrangements of the letters in Mississippi having no consecutive s's=70X105=7350. So, the answer is 7350.Hence, the distinct permutations of the letters of the word MISSISSIPPI when four I's do not come together = 34650 – 840 = 33810.
