You add everything with the same power of x together, for exmple you have 2x^3 and the 3x^3 the x^3 is the same in both so you just add it to get 5x^3, then you do the same thing for everything collect the like terms, those who have x^2 is only -4x^2 that's the only thing left, so you write it down, and proceed to x

A quadrilateral is drawn on a coordinate plane with vertices at W(-3,1) X(-1,5). Y(0, 3), and Z(-2,-1).
lbvjy [14]

The actions that prove that the quadrilateral is a parallelogram are:

  • Use the slope formula on each side of the quadrilateral and show that opposite sides have the same slope.
  • Use the distance formula on each side of the quadrilateral and show that opposite sides have the same length.

<h3>Quadrilaterals</h3>

Quadrilaterals are polygons that have four sides and four corners

<h3>Parallelograms</h3>

Parallelograms are quadrilaterals that have parallel and congruent opposite sides

For the quadrilateral to be a parallelogram, then the opposite sides must be congruent.

This can be proved using the distance formula

Also, for the quadrilateral to be a parallelogram, then the opposite sides must be parallel.

This can be proved using the slope formula

Hence, the possible actions are (a) and (b)

3.4 hours. The efficiency of a worker is the amount of work divided by time needed. The efficiency of Sanjay alone is 500/6, and the efficiency of Felipe alone is 500/8. When they work together, their combined efficiency is 500/6+500/8=3500/24. Therefore, they need 500/(3500/24)=24/7=3.4 hours.
