Answer:
5/1 or 5:1
Step-by-step explanation:
KU and UM are equal to each other.
KU = 3x + 3
UM = 4x - 4
3x + 3 = 4x - 4
3x = 4x - 7
-x = -7
x = 7
If you plug that into either one of the equations, you get 24.
3(7) + 3
24
So depending on your question, x is 7, KU is 24, and UM is 24.
Answer:
30
Step-by-step explanation:
Perimeter of rectangle = 5y - 1 + 4y + 2 + 5y - 1 + 4y + 2
= 18y + 2
18y + 2 = 128
18y = 128 - 2
= 126
y = 126 ÷ 18
y = 7
Length of AD = 4y + 2
= 4(7) + 2
= 28 + 2
= 30
