Answer:

  14(x +5)

Step-by-step explanation:

The denominator of the first expression is ...

  2x+10 = 2(x +5)

The denominator of the second expression is ...

  7x +35 = 7(x +5)

The least common denominator (LCD) is the product of the unique factors in these denominators:

  2×7×(x +5)

  = 14(x +5) . . . . least common denominator

  = 14x +70
