Step-by-step explanation:
15+10=5(3+_)
25=5(3+_)
25 divide by 5 equals 5
5-3=2!
When you distribute the 5 to the 3 and the 2 it makes 15 + 10 which is equal to the other side of the equation.
Answer: 6x^4 √10t^12
4.5
Use sin64=x/5 and simplify to
5sin64 and plug it into a calculator to get 4.49 which is 4.5
52.1 x 2.29 = 119.309
