Answer:

<u>We can verify each sum by checking for the sum of one term, which is 2:</u>

  • A. n = 1 ⇒ 2*1 = 2, correct
  • B. n = 1 ⇒ 2(2) = 4, incorrect
  • C. n = 1 ⇒ 1 + 2 = 3, incorrect

So A is the correct choice

Write a polynomial that represents the area of the square.
Tema [17]

Answer:

The answer to your question is Area = 49n² - 70n + 25    

Step-by-step explanation:

Data

Length of the side = 7n - 5

Formula

Area of a square = side x side

Process

1.- Substitute values

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

2.- Expand

Area = 49n² - 35n - 35n + 25

3.- Simplify

Area = 49n² - 70n + 25    

4.- The polynomial is 49n² - 70n + 25

How do you expand (x-10)(x-10)​
denpristay [2]
1 Answer
1.multiply the First terms. x⋅x=x2.
2.multiply the Outside terms. x⋅10=10x.
3.multiply the Inside terms. −10⋅x=−10x.
4.multiply the Last terms. −10⋅10=−100.
5.add all of the answers together. x2+10x−10x−100.
6.combine like terms. x2+10x−10x−100. =x2−100.

What is the scale factor of the dilation?
wel

Answer:

3

Step-by-step explanation:

D(1 , 1) to D'(3, 3)

so x (1 x 3)= 3

    y (1 x 3) = 3

SF = 3

D(1 , 5) to D'(3, 15)

so x (1 x 3)= 3

    y (5 x 3 ) = 15

SF = 3

Same on coordinate points B to B' and C to C'

so SF = 3

Answer:

The exact value of tan(M) is 5/12 ⇒ answer (C)

Step-by-step explanation:

* Lets revise the trigonometry functions

- In ΔABC

# m∠B = 90°

# Length of AB = a , length of BC = b and length of AC = c

# The trigonometry functions of angle C are

- sin(C) = a/c ⇒ opposite side to ∠C ÷ the hypotenuse

- cos(C) = b/c ⇒ adjacent side to ∠C ÷ the hypotenuse

- tan(c) = a/b ⇒ opposite side to ∠C ÷ adjacent side to ∠C

* Now lets solve the problem

- In ΔONM

∵ m∠N = 90°

∵ MN = 12

∵ ON = 5

∵ tan(M) = ON/NM ⇒ opposite side of ∠(M) ÷ adjacent side of ∠(M)

∴ tan(M) = 5/12

* The exact value of tan(M) is 5/12
