Length (l) = 13 feet
Width (b) = 9 feet
Perimeter = 2(l + b)
= 2(13 + 9)
= 2×21
= 42 feet
Answer:

Step-by-step explanation:
We have to use the law of indices for finding the equivalent expression.
We square 8, which is 64 and multiply the two powers.
We multiply the 2 powers giving us,
, which simplifies to 2.
×
=
This is the answer as we multiply the two indices together.
I hope this helps!! ^-^

Required
Which of a to d has no solution
(a)
and 
We have: 
Sole for m



Divide by 6

So, we have:
and 
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
