Perimeter of rectangle = 2(l+w)
So, 54cm = 2(l+9cm)
=> 54cm = 2l + 18cm
=> 54cm - 18cm = 2l
=> 36cm = 2l
=> 36cm/2 = l
=> 18cm = l

Answer: -27
Step-by-step explanation:
replace x for -8.
3(-8) - 3
3 × -8 = -24
-24 - 3 = -27
The correct option is (A)
Explanation:Just like the previous answer, add all the boxes:
There are 6 (x^2) boxes;
There are 11 (x) boxes;
And the constants = 3
So it becomes:

And the product would be the same.
(2x+3)(3x+1)
2x(3x+1) + 3(3x+1)
6x^2 + 2x + 9x + 3

(same)
