What is the answer to 0.03x^2+0.07x+0.03=0

x=(-7+√13)/6

or

x= (-7 -√13)/6

Step-by-step explanation:

0.03x^2 = 0.07x + 0.03=0

first, multiply everything by 100 to make life easier

3x^2 +7x+3=0

then use quadratic formula

D=b^2 -4ac

D=49-3*3*3 = 13

x=(-7+√13)/6

or

x= (-7 -√13)/6

his chances of getting a coin of higher value is 4/19

step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
