Answer:
AB = ![\sqrt{34}](https://tex.z-dn.net/?f=%5Csqrt%7B34%7D)
Step-by-step explanation:
Calculate the distance d using the distance formula
d = √ (x₂ - x₁ )² + (y₂ - y₁ )²
with (x₁, y₁ ) = A(- 2, 1) and (x₂, y₂ ) = B(3, 4)
d = ![\sqrt{(3+2)^2+(4-1)^2}](https://tex.z-dn.net/?f=%5Csqrt%7B%283%2B2%29%5E2%2B%284-1%29%5E2%7D)
= ![\sqrt{5^2+3^2}](https://tex.z-dn.net/?f=%5Csqrt%7B5%5E2%2B3%5E2%7D)
= ![\sqrt{25+9}](https://tex.z-dn.net/?f=%5Csqrt%7B25%2B9%7D)
= ![\sqrt{34}](https://tex.z-dn.net/?f=%5Csqrt%7B34%7D)
Answer:
x = 9/2 or x= 4.5
Step-by-step explanation:
you factor out the equation:
5x-15=3x-6
+15 +15
5x=3x+9
-3x -3x
2x=9
x=9/2 or 4.5
