Answer:
4 and a half hours
Step-by-step explanation:
12 times 4 is 48 and to get to 54 he worked for another half hour which got him 6 dollars
A² + b² = c²
20² + n² = (n+2)²
400+ n² = (n+2)(n+2)
400 + n²=n² + 2n + 2n +4
400 + n² = n² +4n +4
400 + n²-n² = n²-n² + 4n+4
400 = 4n + 4
400-4 = 4n +4-4
396 = 4n
396/4 = 4n/4
n= 99
20²+ 99² = (99+2)²
400 + 9801 =10201
10201=10201
Answer:
a = 4
Step-by-step explanation:
24a+14=6(8a+3)-26a+4
24a+14 = 48a+18-26a+4
24a-48a+26a = 18+4-14
2a = 8
a = 4
