Answer:
38 miles per gallon
Step-by-step explanation:
465 miles / 12 gallons
38 miles / gallon
X^2 - x - 42 = x^2 - 6x + 7x - 42 = x( x - 6) + 7(x - 6) = (x-6)(x+7);
The correct answer is a.
Answer:
No
Step-by-step explanation:
3x - 6 = 12
3x = 18
x = 6
The only solution of the equation 3x - 6 = 12 is x = 6.
Answer: No
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
