Step-by-step explanation:
<u>Step 1: Define</u>
x² - 8x + 15 = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
- [Subtraction Property of Equality] Subtract 15 on both sides: x² - 8x = -15
- Complete the Square [Addition Property of Equality]: x² - 8x + 16 = -15 + 16
- [Complete the Square] Simplify: (x - 4)² = 1
- [Equality Property] Square root both sides: x - 4 = ±1
- [Addition Property of Equality] Add 4 on both sides: x = 4 ± 1
- Evaluate: x = 3, 5
So the ratio of "The scale on a map indicates that 1 inch corresponds to an actual distance of 95 miles.", is...
Scale on map : Actual Distance
1 : 95 miles
We need to find the actual distance for 4.5 inches on the map.
4.5 : x
Just multiply 4.5 with 95 and you would get 427.5 miles.
So the actual distance between the two cities is 427.5 miles.
