X-2=17
add two to both sides to cancel out the 2
x=19
Step-by-step explanation: x+(x+2)+(x+4)+(x+6)+(x+8)+(x+10)=126
6x+30=126
6x=96
X=16
Since x is the first number , x+6 is the fourth even number .
Thus, the fourth number in the sequence is 22
Step-by-step explanation:
18/24>20/24 you have to flip the sign to make it correct
Answer:
Step-by-step explanation:
1: Base Surface Area = π×72
= 153.9380400259 millimeters2
Lateral Surface Area = π×7×√72 + 142
= 344.215921821 millimeters2
Total Surface Area = 498.1539618469 millimeters2
Rounded = 500 millimeters2
2:Base Surface Area = π×52
= 78.539816339745 centimeters2
Lateral Surface Area = π×5×√52 + 102
= 175.62036827602 centimeters2
Total Surface Area = 254.16018461576 centimeters2
Rounded 300 centimeters2
