Answer:
1. 24
2. B
Step-by-step explanation:
1. 7^2+x^2=25^2
49+x^2=625
x^2=576
x=24
2. 15^2+36^2=39^2
225 + 1296 = 1521
57.63 or 57.6
This works because you get 55 and then you’d get 84 so you’d multiply by 7. This would be 7 and you would put a decimal and carry a 0 so it would 70. So you’d end up with 57.6

Answer:
5 and 15
Step-by-step explanation:
Let x represent the smaller number. Then the larger is x+10. The sum is ...
2x +3(x+10) = 55
5x +30 = 55
5x = 25
x = 5
The two numbers are 5 and 15.
