Answer:
x^2 – 4 = 0
Step-by-step explanation:
When x = - 2,
x^2 - 4 = 0
( - 2 )^2 - 4 = 0
4 - 4 = 0
When x = 2,
x^2 - 4 = 0
2^2 - 4 = 0
4 - 4 = 0
Answer:
Step-by-step explanation:
Let’s break this apart.
Box= 12cm x 8cm x 6cm
Cube= 2cm x 2cm x 2cm
How many cubes fit in the box?
calculate the volume of the box. To do this, multiply the length by the width by the height (L x W x H)
12 x 8 x 6 = 576cm cubed
2. Calculate the volume of the cube. Once again we multiply L x W x H
2 x 2 x 2 = 8cm cubed
3. Next we divide the volume of the box by the volume of the cube
576 / 8 = 72 cubes
Therefore, it would take 72 cubes to fill a box.
Answer:
n = 0.0025
Step-by-step explanation:
400g —————> 1kg
Then
400g —————> 1000g
or 1000/400 = 2.5 ⇔ 400 × 2.5 = 1000
Then
1g ———————> 2.5 × 1 = 2.5g = 0.0025kg
The answer is: [A]: " 18 " .
