Answer:
(3,10)
Step-by-step explanation:
Let Q be (x,y)
(x+15)/2 = 9
x = 3
(y + 6)/2 = 8
y = 10
137.5 miles or 138 miles covered in 2.5 hours. (if that's what you're looking for)
A(-4,5)
B(-3,1)
C(-5,2)
A rotated(3,1)
B rotated(2,5)
C rotated(4,4)

Answer:
76.5 cm²
Step-by-step explanation:
Given the triangles are similar , then
ratio of sides = a : b , so
ratio of areas = a² : b²
Here ratio of sides = 9 : 13.5 = 2 : 3
ratio of areas = 2² : 3² = 4 : 9
let x be the area of Δ DEF and using proportion
= ( cross- multiply )
4x = 306 ( divide both sides by 4 )
x = 76.5
The area of Δ DEF = 76.5 cm²
