Answer:
length is 15.5 and the width is 12.5
Step-by-step explanation:
Length rectangle = 3cm. longer than its width.
Rectangle perimeter = 56 cm.
find its dimensions?
P = 2L +2w
L= w + 3
P= 56
P = 2L +2w
56 = 2(w+3) +2(w)
56 = 2w +6 + 2w
4w= 56 - 6
4w = 50
w = 50/4
w = 12.5
L= 12.5 +3 = 15.5
L= 15.5
Solution:
Length= 15.5 cm
Width = 12.5 cm
i know it looks complex but i hope this helps :)
Answer:
6
Step-by-step explanation:
Let's simplify step-by-step.
8w+9−(8w+3)
Distribute the Negative Sign:
=8w+9+−1(8w+3)
=8w+9+−1(8w)+(−1)(3)
=8w+9+−8w+−3
Combine Like Terms:
=8w+9+−8w+−3
=(8w+−8w)+(9+−3)
=6
