Answer:

x = 19/2 and 1/2

Step-by-step explanation:

General form of a quadratic equation is expressed as:

ax²+bx+c = 0... (1)

The quadratic formula used to find the solution to the equation is given as:

x = -b±√b²-4ac/2a

Given the quadratic trinomial: x²−10x + 4.75... (2)

a) To get a, b and c, we will compare the given equation (2) to the general equation (1)

Based on the comparison,

a = 1, b = -10 and c = 4.75

b) We will substitute this values of a, b and c into the quadratic formula to have;

x = -(-10)±√(-10)²-4(1)(4.75)/2(1)

x = 10±√100-19/2

x = 10±√81/2

x = (10±9)/2

x = (10+9)/2 and (10-9)/2

x = 19/2 and 1/2

The answer to the equation are 19/2 and 1/2

RSB [31]

Answer:

x=8

Step-by-step explanation:

p=(l+b)

140=2(x+4x-2)

140=2(9x-2)

140=18x-4

140+4=18x

144=18x

144/18=x

8=x
