In emily's physics class, she had to solve the equation 9 = 12at2 + ut for u. each step of her work is shown below. use the drop-down menus to explain each step.

Step-by-step explanation:

we have

Solve for u

That means-------> isolate the variable u

step 1

Subtract   both sides

step 2

Divide by   both sides

answer: sorry i dont really know but can we talk all my friends r gone and im bored

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.
