Answer:
Area = x^2+4x+3
Step-by-step explanation:
The volume of a box is given by the expression
x^3 + 3x^2 - x-3. The height of the box is given by the expression x-1.
volume of the box = Length * width * height
L is the side length of the box;
Given
V(x) = x^3 + 3x^2 - x-3
Factorize
V(x) = x^2(x+3)-1(x+3)
V(x) = (x^2-1)(x+3)
V(x) = (x+1)(x-1)(x+3)
V = LWH
V = Area * Width
Since the height of the box is x - 1
Area = (x+1)(x+3)
Expand
Area = x^2+3x+x+3
Area = x^2+4x+3
The large rectangle is 3 times 6 but theres two so its 2 x 3 x 6
the medium rectangle is 2 times 6 but again there is two so 2 x 2 x 6
the small rectangle is 2 times 3 and once more there is two so 2 x 2 x 3
Answer:
school is a problem
Step-by-step explanation:
Have a great day!!!
2w + 2l = 25
2 * 2 + 2l = 25
<em><u>Simplfiy.</u></em>
4 + 2l = 25
<em><u>Subtract 4 from both sides.</u></em>
2l = 21
<em><u>Divide both sides by 2.</u></em>
l = 10.5
Now that we have the value of l, we can find the area.
A = lw
A = 10.5 * 2
A = 21.
The length is 10.5cm.
The area of the rectangle is 21cm^2
