Answer:
Volume of rectangular prism = 1200 cubic inches
Step-by-step explanation:
Given that:
Length of rectangular prism = 10 inches
Width of rectangular prism = 8 inches
Height of rectangular prism = 15 inches
Volume of rectangular prism = Length * Width * Height
Volume = 10 * 8 * 15
Volume = 1200 cubic inches
Hence,
Volume of rectangular prism = 1200 cubic inches
15 miles in 20 minutes.
there are 60 minutes in one hour.
Convert it from minutes to hour
X=8+y
x+y=70
Rewrite the first equation to x-y=8
Copy the second equation x+y=70
Add the two equations and you get 2x=78
Therefore, x=39. Since this is the bigger number the smaller number(y) would have to be 31 because you subtract 8 from x which is 39. 39 is your answer.
<span>(2x^4+3x^2+7)-(3x^3+9x+4)
you have to take away the </span>parentheses first
2x^4 + 3x^2 + 7 - 3x^3 - 9x - 4
combine like terms
2x^4 - 3x^3 + 3x^2 - 9x + 3
