Answer:
40 units
Step-by-step explanation:
So first if it was a scale factor of 2.5 you would multiply it by 2.5 for each side. So for the side of 3 you would multiply it by 2.5 which is 7.5 so that side and the other side across from it would be 7.5 units. Then for the next one there is 5 units so you do the same 5x2.5 is equal to 12.5 so will the one below it.
Then it would be (7.5 * 2) + (12.5 * 2)= 15+25+40
So then the perimeter would be 40 units.
Answer:
The numbers are 50 & -72.
Step-by-step explanation:
Let the first number is x and the second number is y.
According to the question:-
x + y = -22 ........(1)
x - y = 122 ........(2)
By adding equation 1 & 2-
2 x = 100
x = 50
Put X =50 in equation (1)-
y = -22 -50
y = -72
Hence the numbers are (50, -72).
