A,b,d,e,f,h would be similar because they are all quadrilaterals (they all have four sides) and c,g would be the same because they are both triangles
Answer:
Perimeter: perimeter = (12 x 2) + (x-2 times 2)
Area: 12 x (x-2)
Step-by-step explanation:
I hope im right im only in grade 6 so wouldnt trust me with that :/
Answer:
Width = 18 inches
Length = 59 inches
Step-by-step explanation:
The length of a rectangle is five more than triple the width. If the perimeter is 154 inches, what are the dimensions
Perimeter of a rectangle = 2L + 2W
The length of a rectangle is five more than triple the width.
L = Length = 5 + 3W
W = Width
If the perimeter is 154 inches, what are the dimensions
Hence,
154 = 2L + 2W
154 = 2(5 + 3W ) + 2W
154 = 10 + 6W + 2W
Collect like terms
154 - 10 = 8W
144 = 8W
W = 144/8
W = 18 inches
Length = 5 + 3W
Length = 5 + 3(18)
Length = 5 + 54
Length = 59 inches
Move all terms that dont contain y to the right side and solve and you get:
y=4x/3-7
Hope this helps
the answer is 65 degrees because the line in the middle is a 180 degree angle and 180-115=65. hope this helps :)
