<em>Answer:</em>
<em>The expression which is does not correct is A. 9 + 12</em>
<em>Step-by-step explanation:</em>
<em>Length of the rectangular garden = 12 feet</em>
<em>Width of the rectangular garden = 9 feet</em>
<em>We need to find the perimeter of the garden.</em>
<em>The perimeter of the garden is given by the formula = 2 × (Length + Width)</em>
<em>⇒ Perimeter = 2 × (12 + 9)</em>
<em> = 2 × 12 + 2 × 9</em>
<em> = 12 + 12 + 9 + 9</em>
<em>So, All the options B. , C, and D. are correct to find the perimeter of the rectangular field.</em>
<em>Therefore, The expression which is does not correct is A. 9 + 12</em>

<h3>
In total Jane initially had 11 dimes.</h3>
Step-by-step explanation:
The number of cents Sam has now = 70 cents
The number of cents Jane has now = 75 cents
Initially Sam had only nickels, and Jane had only dimes.
Now, since Sam has $0.7
⇒ He holds 7 dimes.
⇒He gave away 7 nickels.
Also, Jane has $0.75
Now, 0.35 = 7 x (0.05) = 0. 05 x 7 nickels
So, Jane now has 7 nickels and 4 dimes.
Hence, in total Jane initially had 11 dimes.
