Answer:
The length will be 5 feet, width will be 4 feet.
Step-by-step explanation:
Given:
volume of the box = 40 ft^3
Length of the box = (2x-1)ft
Width of the box = (3x-5)ft
Height of the box = 2ft,
To Find:
The length and width of the box = ?
Solution:
We know that,
-----------------------(1)
Solving eq(1) by quadratic equation formula
Substituting the values
x = 3 x =-0.833
Neglecting the negative value,
we have x = 3
Then the length will be
(2(3)-1) = (6-1) =5 ft
The Width will be
(3(3)-5) = (9-5) = 4 ft
In order to solve an equation by factoring, it should be that the equation is equal to zero.
m^2 + 8m + 7 = 0
For this case we have, to do completing the square in order to factor this equation.
<span>
m^2 + 8m = -7
</span><span>m^2 + 8m + 16 = -7 +16
</span><span>(m+4) (m+4) = 9
</span><span>(m+4)^2 = 9
Take the square root of both sides,
m+4 = 3
m = -1</span><span>
