Who ever can guess 9 cubed +19 divided by 3 will get these points

87.3333 I think.

Step-by-step explanation:

9x9+19/3

9x9=81

81+19/3

19/3=6.33

81+6.333=87.3333

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c
