Answer:
Step-by-step explanation: (x,y) (4,2)
Since each point of the triangle is going to be 1.5 times as far from the center of dilation, each side will increase by a factor of 1.5..
3 x 1.5 = 4.5m
4 x 1.5 = 6m
5 x 1.5 = 7.5m
So the perimeter of the new triangle will be 4.5 + 6 + 7.5 = 18 meters

Answer:
<u>The numbers are 40 and 49</u>
Step-by-step explanation:
Smaller number = x
Larger number = y
Let's write our system of equations:
x + y = 89
3x = y + 71
***************************
x = 89 - y
Substituting x in the 2nd equation and solving for y:
3 (89 - y) = y + 71
267 - 3y = y + 71
-3y - y = 71 - 267 (Like terms)
-4y = - 196
y = -196/-4
y = 49
Solving for x in the 1st equation:
x + y = 89
x + 49 = 89
x = 89 - 49
x = 40
<u>The numbers are 40 and 49</u>
