# 2( 5t + 14)

Explanation:

Multiply across the parenthesis then combine like terms.
Find any common factors and divided the common factors out and multiply the remaining terms by the common factors.

# 6( 3 + t) = 18 + 6t#

# ( 2t + 5) xx 2 = 4t + 10#

Combining these gives

# 18 + 6t + 4t + 10#

Combining like therms gives

# 10 t + 28#

There is a common factor of 2 between the terms so

# 2 ( 5t + 14) #
