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
X/3=x+2/5
5x = 3(x+2)
5x = 3x + 6
2x = 6
x = 3
answer
D.3
Answer:
128 feet squared
Step-by-step explanation:
you multiply 4 by 4 to get 16 ,
then you multiply 7 by 4 and get 28,
also multiply 28 by 4 and get 112 ,
finally add 112 and 16 to get 128
The area of the associated sector is: 120π
<h3>What is a sector?</h3>
A sector is the portion of the area of a circle surrounded by an arc and two radii.
Analysis:
Area of a sector = ∅/360 x π
∅ = 75°
r = 24 units
Area of sector = 75/360 x π
= 120
square units
In conclusion, the area of the associated sector is 120π square units

Roll dice and flip coin:
Probability of rolling a cube and getting a 3 = 1/6 .
Probability of flipping a coin and getting HEADS = 1/2 .
Probability of both = (1/6) x (1/2) .
You do the multiplication.
4 blue, 2 green, 6 red
Probability of a blue on the first draw = 4 out of 12 marbles = 1/3 .
Without putting the blue back in ...
Probability of a red on the next draw = 6 out of 11 marbles = 6/11 .
Probability of both = (1/3) x (6/11) .
You do the multiplication.
