The answer is 7
3x-3=18 (take 3 to the other side to solve for x)
3x=18+3 (3 will be positive)
3x=21 (divide both sides by 3)
x=7
Answer:
1512
Step-by-step explanation:
18 times 21 times 8 = 3024
since it's a triangular prism, u half it
3024 div 2 = 1512
The volume should be l(w)(h)= v so 6.3(14.7)(8.4)=29.4 in

option 2 I think sorry if its incorrect
Answer: ![\pi 36r^{2}](https://tex.z-dn.net/?f=%5Cpi%2036r%5E%7B2%7D)
Step-by-step explanation:
ALRIGHT ARE YOU READY FOR EPIC MATH TIME?
because i know i am. so lets get this bread.
WATCH: we have ![\pi (3r)2(6r)](https://tex.z-dn.net/?f=%5Cpi%20%283r%292%286r%29)
interesting... that first character is called pi. maybe i should have said, "lets get this pi".
so now lets do some algebra. i am going to work from right to left. lets multiply 6r by 2. that gives us 12r. now we have... ![\pi (3r)(12r)](https://tex.z-dn.net/?f=%5Cpi%20%283r%29%2812r%29)
WE ARE MAKING EPIC PROGRESS, AREN'T WE?
lets multiply 12r by 3r. then we have....
![\pi 36r^{2}](https://tex.z-dn.net/?f=%5Cpi%2036r%5E%7B2%7D)
notice how i multiplied 12 by 3 and also r by r (which gives 36 and
respectively)
so your simplified expression is: ![\pi 36r^{2}](https://tex.z-dn.net/?f=%5Cpi%2036r%5E%7B2%7D)
