If the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio is represented by the expression x − 9:
1. what is the expression for the width of the patio? Explain and show all work.
2. what special rectangular shape is the patio? (can be determined by side lengths).
Explain and show all work.

1)

2) Rectangular shape is square shape patio !

Step-by-step explanation:

Here we have ,  the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio is represented by the expression x − 9: We need to find

1. what is the expression for the width of the patio? Explain and show all work.

We know that area of rectangle =

⇒

Factorizing RHS:

⇒

⇒

⇒

⇒

2. what special rectangular shape is the patio?

Now , we see that

A rectangle whose length & width are equal is known as a square ! Hence ,  Rectangular shape is square shape patio !

i dont know sorry

step-by-step explanation:

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
