Solution:
1. Consider two trees which are 5 m apart. Suppose one tree is located at a distance of 45 m from my house and another tree is located 50 m from my house. Represent , distance of two trees from my house in terms of Quadratic function.
Solution:
Let location of my house when map of planet earth is drawn or on globe=x
⇒(x-45)(x-50)=0
⇒ x² - 45 x - 50 x +45 × 50 =0
⇒ x² - 95 x + 2250=0
2. Suppose age of me and my brother is 6 and 10 years. The Product of difference between age of me and my mother who is x years old and my brother and mother is 780.Find my mother's age.
Solution: Age of my mother = x years
→(x-6) × (x-10)= 780,
if you will solve it , the value of x= 36 years
Answer:
B? I believe? sorry if it's wrong
Neither do i lol drop out of school
4b-3 .. you use distributive property and multiply 3*b-1 then you have 7b-3b-3 then you combine like terms and subtract 3b from 7b and get 4b-3
