Answer:
828
Step-by-step explanation:
Missing leg of triangle:
√15²-12²= √225-144=√81=9
Triangle faces= 2*1/2*12*9= 108
Base= 20*9= 180
Front face= 20*15= 300
Back face= 20*12= 240
Total= 108+180+300+240= 828
Second choice
Answer:
No solution
Step-by-step explanation:
4(8n-1)=19+32n
Distribute the 4 to 8n-1
32n-4=19+32n
Add 4 on both sides
32n=23+32n
Subtract 32n on both sides.
Both 32n's cancel out so you are left with 0=23 which is false.
There is no solution
Answer:
You split the top and bottom and add them in the end
Step-by-step explanation:
so find the cylindar then find the half circle on the top after you do that you would add them.
hope that helps <3

2n/3 - 11 = n + 4
Add 11 to both sides:
2n/3 = n + 15
Multiply both sides by 3:
2n = 3n + 45
Isolate n:
-n = 45
n = -45
