Q. Add. Write your answer in simplest form.\newline−25+85-2\sqrt{5} + 8\sqrt{5}
  1. Combine like terms: Combine the like terms −25-2\sqrt{5} and 858\sqrt{5}.\newlineIdentify the like terms which are both terms with 5\sqrt{5}.\newline−25+85=(−2+8)5-2\sqrt{5} + 8\sqrt{5} = (-2 + 8)\sqrt{5}
  2. Simplify expression: Simplify the expression (−2+8)5(-2 + 8)\sqrt{5}. Perform the addition inside the parentheses. (−2+8)5=65(-2 + 8)\sqrt{5} = 6\sqrt{5}

Question
According to Newton's Second Law of Motion, the sum of the forces that act on an object with a mass mm that moves with an acceleration aa is equal to m⋅am \cdot a. An object whose mass is 8080 grams has an acceleration of 2020 meters per seconds squared. What calculation will give us the sum of the forces that act on the object, in Newtons (which are kg⋅ms2\frac{\text{kg} \cdot \text{m}}{\text{s}^2})?\newlineChoose 11 answer:\newline(A) 80⋅2080 \cdot 20\newline(B) 80⋅1000⋅2080 \cdot 1000 \cdot 20\newline(C) 801000⋅20\frac{80}{1000} \cdot 20\newline(D) 80602⋅20\frac{80}{60^2} \cdot 20
