Given:
Rectangle shape.
Length is 3 feet longer than its width
Width is unknown let it be x.
Perimeter is 26 feet
Perimeter = 2Length + 2Width
26 ft = 2(x+3) + 2x
26 ft = 2x + 6 + 2x
26 ft = 4x +6
26 ft - 6 = 4x
20 ft = 4x
20 ft / 4 = x
5 ft = x
The width is 5 feet.
Length is 3 ft longer than the width. Thus, it is 8 feet.
To check:
perimeter = 2L + 2W
26 ft = 2(8ft) + 2(5ft)
26 ft = 16 ft + 10ft
26 ft = 26 ft
Here is your answer, you just count to 10... Simple as that.
Answer:
d = -4
Step-by-step explanation:
8d-4d-6d-8=2d
-2d - 8 = 2d
-2d = 2d + 8
-4d = 8
d = -4

The answer is 3.75 cm^3.
First you have to change 12 mm to cm, which would be 1.2 cm. The formula for the volume of a triangular prism is 1/2 x a x c x h. So, 1/2 (2.5) x (1.2) x (2.5) = 3.75 cm^3
