Answer:
Scuba diver started at 2 feet above the sea level, dove down 20 feet, and rose up 8 feet
Step-by-step explanation:
The initial number is 2 which is more than 0 that means the diver did not start at a ground level but above than that.
The negative 20 denotes that he went down the sea level, to the extent of the number provided in feet.
Further, after that dive the positive number provides the height in feet covered to rise up from the down level of dive.
Answer:
Cristal is correct because 7 x 600 is less than 6 x 7,000.
Step-by-step explanation:
Because they are just switching the numbers 7 and 6 and 7 x 6 = 6 x 7, you have to look at the number of zeros. As you can see, 7,000 has 1 more zero than 600, so Cristal is correct. Just like I said 7 x 6 and 6 x 7 is interchangeable, so is 7 x 600 and 6 x 700, they both equal 4,200. However, 6 x 7,000 is 42,000.
Hope this helps! If you have any additional questions please don't hesitate to ask me or your teacher to be sure you master the subject. Stay safe and please mark brainliest! :)
Answer:
Equation for the perimeter of prism's square face: 16x + 12
Step-by-step explanation:
Volume of Square prism = Length * Width * Height
= 144 x^3 + 216 x^2 +81 x
taking 9x common = 9x( 16 x^2 + 24 x + 9)
= 9x ( (4x)^2 + 2(4x)(3) + (3)^2 )
= 9x ( 4x+3)^2
so the length is 9x, width is 4x+3 and height is 4x+3
Now, Perimeter of prism's square face = 2* Width + 2 * Height
= 2* (4x+3) + 2* (4x+3)
= 8x +6 + 8x + 6
= 16x +12
