Answer:
A. length = 23 cm; width = 5 cm
Step-by-step explanation:
So if 4 times the width would be 
and 3 more than would be 
, the equation would be 
. If the perimeter is 56, then the new equation, 
can be formed. This simplifies to 
, then to 
, then to 
, and finally, 
. So the width is 5, and now plug it into the first equation.
, becomes 
, becomes 
.
So the dimensions are: length = 23 cm, width = 5 cm.
*And just to be sure, 
which is correct.

Answer:
x < -24(option
Step-by-step explanation:
-¼x - 12 > -6
Add 12 to both sides
-¼x - 12+12 > -6+12
-¼x > 6
Divide both sides by -¼
x < 6 ÷ -¼
Please note that the inequality sign changes when divided by negative (minus). This is a rule in inequalities.
x < 6 × -4
x < -24
