Answer:
Option C.
Step-by-step explanation:
we have
Solve for x
That means ---> isolate the variable x
Multiply by 8 both sides to remove the fractions
Multiply by -1 both sides
Remember that
When you multiply or divide both sides of an inequality by a negative number, you must reverse the inequality symbol
Divide by 5 both sides
Answer:
Therefore,
The length of the sides of the squares is
Step-by-step explanation:
Let "x" be the length of Cut Square,
As the tin size(Dimension) is
20 cm × 50 cm
So the size(Dimension) of box will be
(20 - 2x) × (50 - 2x)
Length = 50 - 2x
Width = 20 - 2x
Area of base of box = 216 cm²
To Find:
x = ?
Solution:
Area of Rectangular field is given by
Substituting the values we get
Applying Distributive property we get
Dividing throughout by 4 we get
On Factorizing we get
As x cannot be 28 because tin size is 20 cm × 50 cm i.e longer than 20
Therefore,
Therefore,
The length of the sides of the squares is
