Can someone help me ?

Actually Welcome to the Concept of the rectangles.

here, l = 10 , b = 7

hence, perimeter of rectangle = 2(l+b)

=> 2(10+7) => 2(17) => 34 units

hence the perimeter is 34 units.

step-by-step explanation:

the orientation of the parabolas can easily be found by analysing the power of x and y and their signs. if x is squared , parabola opens up and also if its coefficient is negative it opens down. if y is squared , the parabola opens right and also if its coefficient is negative it opens left. however in order to do the above analysis our equation must be in standard form .

our parabola is

which is not standard form of any parabola . hence we square on both hand side and convert it into standard form.

hence we see that x is squared and its coefficient is non negative . there for it opens up.

angle uzt is congruent to angle tzy. angle vzw is congruent to angle yzx.
