Answer:
8x+12
Step-by-step explanation:
Remember that perimeter is all the sides combined. A rectangle has the same length and width for both sides.
P=2l+2w
P=2(4x-6)+2(12)
P=8x-12+24
P=8x+12
T>L+D/B
(Assume no parentheses missing and use PEMDAS rule)
Subtract L from both sides
T-L > L-L + D/B
T-L>D/B
Multiply both sides by B (assuming B>0)
B(T-L)>D/B*B
B(T-L)>D
Interchange two sides,
D<B(T-L) (if B>0)
if B<0, then D>B(T-L)
