antiseptic1488 [7]

Answer:

Step-by-step explanation:

Samantha deposit $300 in an account that earns an annual interest rate of 2.5%.

Now, Samantha after nine months of deposit computes the simple interest.

How do you solve 2x(x+3)=(x+1)(2x-5)
gregori [183]
Distribute and get 2x^2+6x=2x^2+2x-5x-5
add like terms and get 2x^2+6x=2x^2-3x-5
subtract 2x^2 from both sides and get
6x=3x-5
subtract 3x from both sides
3x=5
divide both sides by 3
x=5/3
