Answer:
It's 3 x 7 pond or a 7 x 3 pond
Step-by-step explanation:
Let the rectangular pond have dimensions l x b.
ATQ, l*b=21 and 2(l+b)=20. Solving it, we get l=3 or 7 and b=7 or 3.
As a rule the product of an ODD number of NEGATIVE SIGNS is always NEGATIVE
An the product of an EVEN number of NEGATIVE SIGNS is always POSITIVE
Then the following statement is the right one:
Negative, because the product (-7)(-2) is positive, and the product (-5)(1) is negative and the product of a positive and a negative number is negative
Answer:
D. Positive 14.
Step-by-step explanation:
The absolute value is the distance between a number and zero. The distance between -14 and 0 is 14. Therefore, the answer is positive and not negative.
Hope this helps! :D

Answer:
54.6 units
Step-by-step explanation:
Tangents from an external point to a circle are congruent, then
top tangent = 9.2 × 2 = 18.4
Thus
perimeter = 18.4 + 18.5 + 17.7 = 54.6 units
