The slope is equal to -4.
Hope this helps!
Lenght is 4 1/2 cm
P=2L +2W
15cm = 2L + 2(2/3L)
15cm = 2L + 4/3L
15cm = 2 4/3 L
15cm ÷ 2 4/3 = 2 4/3L ÷ 2 4/3
4 1/2cm = L
Check
P=2L +2W
P=2(4.5) +2(3)
15= 9 +6
15=15
3/4x+3-2x=-1/4x+1/2x+5
3x+12-8x=-x+2x+20
-5x+12=x+20
-5x-x=20-12
-6x=8
-6x/-6=8/-6
X=8/-6
X=-4/3
Answer:
4
Step-by-step explanation:
-3 + 8 + 9 + (-7) + 13 = 20
20/5 = 4
