Given parameters:
Quadratic expression:
x² - 6x + 7 = 0
Solve using quadratic formula;
x = 
From the equation;
a = 1, b = -6 and c = 7
Input the parameters and solve;
x = 
x = 
x = 
x = 
or 
x = 7 or -1
Answer:
The volume would be 12 inches.
Step-by-step explanation:
Volume is LxWxH
for the lower box, I did
4x2x1=8
For the top half
2x2x1=4
Then i added them together
8+4= 12
Answer:
480 cm ^ 2
Step-by-step explanation:
To calculate the surface area of the figure, we must calculate the surface area of the cube, we know that they are identical, therefore, calculating the area of one is sufficient.
We have that the surface area of a cube is:
A = 6 * a ^ 2
where a is the edge, we know that if it is a cube all its sides are equal, in this case it is 4 centimeters, if we replace we have:
A = 6 * (4 ^ 2)
A = 96
96 square centimeters is the area of a cube, but since the area of the object would be the sum of the area of all the cubes, then:
AT = 96 * 5
AT = 480 cm ^ 2
The surface area of the object formed with the cubes is 480 cm ^ 2
A ratio equivalent to 3:4 is 6:8
