When you multiply 2a by 5a, you are essentially multiplying the coefficients (2 and 5) and the variables (a and a). This results in 10a^2, where the coefficient is the product of 2 and 5, and the variable is the product of a and a, which is a^2. So, 2a times 5a equals 10a^2.

Ah, what a happy little math problem we have here! When you have 2a times 5a, you simply multiply the numbers together and then multiply the variables together. So, 2a times 5a is 10a squared. Just like painting a beautiful landscape, it's all about combining the elements together in a peaceful and harmonious way.
Well, darling, 2a times 5a is simply 10a^2. It's like mixing peanut butter and jelly - a perfect combination. Just remember to keep those variables in check, honey.
10a
You can multiply the constants(numbers) if they have the same variable(letters.)
2a-8+4=45-5a 2a-4=45-5a 2a-4+4=45+4-5a 2a+5a=49-5a+5a 7a=49 / by 7 = A=7
Add them together: 2a+5a = 7a
assuming 5a-a-2a-18=0 2a-18=0 2a=18 and thus a=9
2a + 5a + 3a = 10a
2a + 11a - 5a = 8a
