Answer:
2(10+15)= 50
2(20+5)= 50
Step-by-step explanation:
2(25)=50
2(20+15) = 70
2(2+5) = 14
2(20+5)
2(10+15)
When you add 20+5 together you get 25 which is the same to 2(25)
When you add 10+15 together you get 25 which is the same to 2(25)
28.7
a^2 + b^2 = c^2
25^2 + 14^2 = 821
Square root of 821 is 28.7.
