-60
Step-by-step explanation:
-3 x -4 x -5
12 x -5
-60
negative x negative x negative= negative
Answer:x=6
Step-by-step explanation:
YZ is 1/2 of EF, so the same goes for the other sides. ED is 10, so XY is 5, 5=x-1, solve for x, and you get x=6. And to verify, XY is 7.5, so DF would be double that, so 15=3(x-1), which is correct 15=3(6-1)=3(5)
Length = 2 breadth +6
perimeter= 4(length+ breadth)
168=4(2breadth +6+breadth
42={3breadth+6)
14=breadth +2
breadth =12
length=30
hope u like the answer if yes mark !e brainlist
