Answer:
Step-by-step explanation:
-2.2 - (-1.7) - (-0.4) = -4.2 + 0.3 = -3.9
You have 5 sides
Front 1x6x5=39
Bottom 1x6x3=18
Back 1x6x4=24
Two triangles 2x1/2x3x4= 12 triangle is 1/2bh
Add 39+18+24+12= 93 sq cm

Answer:
-4/5
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-10-(-2))/(9-(-1))
m=(-10+2)/(9+1)
m=-8/10
simplify
m=-4/5
Answer:
<em>The width of the lid is 15 cm</em>
Step-by-step explanation:
<u>The Perimeter of a Rectangle</u>
Given a rectangle of width W and height H, the perimeter is calculated as:
P = 2(W + L)
Jon used 56 cm of ribbon to go around the edge of a rectangular lid. This means the perimeter is:
2(W + L) = 56
Dividing by 2:
W + L = 28
Since the lid was L=13 cm long, the width is:
W = 28 - 13 = 15
The width of the lid is 15 cm
