Find the equation whose roots
are -2/3 and -1/4

12x² + 11x + 2 = 0

Step-by-step explanation:

Given the roots are x = - and x = - , then the corresponding factors are

(x + ) and (x + ) , that is

(3x + 2) and (4x + 1)

The equation is then the product of the factors

(3x + 2)(4x + 1) = 0 ← expand factors using FOIL

12x² + 11x + 2 = 0

b

step-by-step explanation:

calculate the scale factor as the ratio of corresponding sides, image to original, that is

scale factor = = = = 1

8121 because

130,000 divided by 16 is 8121
