Answer:
Hello,
- 6 (x - 2)² - 1
Step-by-step explanation:
- 6 x² + 24 x - 25 = - 6 (x² - 4 x) - 25
= - 6 ( (x - 2)² - 4) - 25
= - 6 (x - 2)² + 24 - 25
= - 6 (x - 2)² - 1
Answer:
4x^2−32x+28
Step-by-step explanation:
First, calculate for the volume of the cube before each edges are cut.
V = e³
where e is the length of each sides. Substituting the known value,
V = (4/5 cm)³ = 0.512 cm³
Then, calculate for the volume of each of the small cubes cut out from the corners.
V = (1/5 cm)³ = 0.008 cm³
Since there are 8 of these small cube, we multiply the volume by 8.
8V = 8(0.008 cm³) = 0.064 cm³
Then, subtracting the volumes will give us an answer of <em>0.448 cm³</em>
