Surface are of a rectangular prism = 2(l x w + l x h + w x h) = 2(10 x 3 + 10x + 3x) = 2(30 + 13x) = 60 + 26x
Volume of a rectangular prism = l x w x h = 10 * 3 * x = 30x
Since surface area = volume
60 + 26x = 30x
4x = 60
x = 15 in
Answer:
If what the sin 90º
Step-by-step explanation:
Answer:
The answer is 7.
Step-by-step explanation:
4 divided by 7 is 0.571428 these just keep repeating over and over again so the closest dividable number of 6 (6 is how many digits there are before it repeats) is 1998 so the 2nd digit in .571428 is 7 hope this helps.

Hello,
answer A
4x+2y=11
x-2=-2y==>2y=-x+2
4x-x+2=11==>3x=9==>x=3
2y=-3+2==>y=-1/2
