Hey there!
We can factor 10a+6 to get our answer.
Remember factoring as the opposite of the distributive property
(i.e factored would by ab+ac and distributive would be a(b+c)).
We can't have a on the outside, since the second term in our expression doesn't contain an that variable.
We take our greatest common factor, or GCF, so it's factored completely.
We have:
2(5a+3).
Hopefully this helps

The equivalent expression is 2(5a + 3)

What is expression?

An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it.

Expression Definition in Math

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division. The terms involved in an expression in math are:

  • Constant: A constant is a fixed numerical value.
  • Variable: A variable is a symbol that doesn't have a fixed value.
  • Term: A term can be a single constant, a single variable, or a combination of a variable and a constant combined with multiplication or division.
  • Coefficient: A coefficient is a number that is multiplied by a variable in an expression.

Given:

10a + 6

  • 10(a + 3)

= 10a + 30

  • 2(5a + 3)

=10a +6

  • 5(5a + 1)

=25a +5

  • 10(a + 1)

=10a +10

Hence, the  equivalent expression is 2(5a + 3).
