Answer:
21 N
Step-by-step explanation:
let mass be m and weight be w
Given w varies directly with m then the equation relating them is
w = km ← k is the constant of variation
To find k use the condition m = 7 , w = 49 , then
49 = 7k ( divide both sides by 7 )
7 = k
w = 7m ← equation of variation
When m = 3 , then
w = 7 × 3 = 21 N

Answer:
(x + 4)(x - 3)
Step-by-step explanation:
x^2 + x - 12 = 0
In order to factorise an equation, one must take into consideration the factors of the values in given equation.
In the factored form, the above equation becomes
(x + 4)(x- 3)
Factors of x^2 = x times x
Factors of -12 = +4 x -3
As shown in the factored form above
