Write a polynomial that represents the area of the square 7n-5, plz help, thank you!
andrey2020 [161]

Answer:

49n² - 70n + 25

Step-by-step explanation:

Area of a square = s²

Where,

s = side length = 7n - 5

Area of the square = (7n - 5)²

= (7n - 5)(7n - 5)

= 7n(7n - 5) -5(7n - 5)

= 49n² - 35n - 35n + 25 (distributive property of equality)

Add like terms

Area = 49n² - 70n + 25

Round of 389,422 in 1,000
Katen [24]
So,

To round the nearest thousand, look at the number in the hundredths place.
If n ≥ 5, round up
If n < 5, round down

4 < 5, therefore round down.

389,422 --> 389,000

Jasmyn is standing at the point of tangency to a wishing
timofeeve [1]

Answer:

The value of   x=17 ft.

Step-by-step explanation:

Diagram of the given scenario shown below.

Given that,

Distance from bench to Jasmyn is   PA=27ft.

Distance from bench to Willard is PB=(2x-7)ft.

From the Question,

The given wishing well is a circle and all the distance are tangent to the circle.

So, Triangle formed by these points are such as ΔPAO and ΔPBO.

Now, taking both ΔPAO and ΔPBO.

   ⇒             AO = BO                                     {Radius of circle are equal}

   ⇒             PO=PO                                     {Common side}

   ⇒          ∠PAO = ∠PBO                              {radius is always perpendicular                                                                          

                                                                           to the point of tangent }

∴            ΔPAO ≅ ΔPBO                                  {By SAS congruence theorem}

Therefore,   PA=PB         ....(1)                             {corresponding part of

                                                                           congruence triangle (CPCT)}

Thus,

   ⇒                2x-7=27                                 {from equation (1)}

   ⇒                      2x=34    

   ⇒                        x=17 ft

Hence, The value of   x=17 ft.
