If the perimeter is 16 feet, the sum of length and width must be 8 feet. Assuming the area is non-zero, possible dimensions (in feet) are ...
1 × 7, 2 × 6, 3 × 5, 4 × 4, 5 × 3, 6 × 2, or 7 × 1.
Answer:
B is the wrong one
Step-by-step explanation:
-7 is less than -9
Find the length of AB
AB²=20²+15²
AB²=400+225
AB²=625
AB=25
then find AD and BD
20²=AD·25
400=AD·25
AD=16
15²=BD·25
225=BD·25
BD=9
now use the geometric mean theorem (name?) to find CD
CD=√(9·16)
CD=√144
CD=12 cm
Answer:
That is 1 as 1+1=2 and twicing it is 4.
That is an example of the Distributive Property!
