We are given statement : The distance between Pittsburgh, Pennsylvania, and St. Louis, Missouri, is 17 miles less than 5 times the distance between Pittsburgh and Cleveland, Ohio.
The distance between Pittsburgh and Cleveland = d.
We need to write an expression for distance between Pittsburgh and St. Louis.
<h3>And it's "17 miles less than 5 times the d".</h3><h3>5 times of d is = 5d.</h3><h3>17 miles less than 5d = 5d -17.</h3><h3>Therefore, 5d -17 expression can you use to represent the distance between Pittsburgh and St. Louis.</h3>
Answer:
x = sqrt(29)/2 - 3/2 or x = -3/2 - sqrt(29)/2
Step-by-step explanation by completing the square:
Solve for x over the real numbers:
x^2 + 3 x - 5 = 0
Add 5 to both sides:
x^2 + 3 x = 5
Add 9/4 to both sides:
x^2 + 3 x + 9/4 = 29/4
Write the left hand side as a square:
(x + 3/2)^2 = 29/4
Take the square root of both sides:
x + 3/2 = sqrt(29)/2 or x + 3/2 = -sqrt(29)/2
Subtract 3/2 from both sides:
x = sqrt(29)/2 - 3/2 or x + 3/2 = -sqrt(29)/2
Subtract 3/2 from both sides:
Answer: x = sqrt(29)/2 - 3/2 or x = -3/2 - sqrt(29)/2
