Answer:

The other sides equal 9cm also because a square has four equal sides.

L=9cm * W=9cm =A

A=81 cm

The length of a rectangle is given by the function l(x)=2x+1, and the width of the rectangle is given by the function w(x)=x+4.

Harlamova29_29 [7]

Answer:

a(x)=2x^2+9x+4

Step-by-step explanation:

We have been given the length and width, as well as the formula to find the area:

Length: 2x + 1

Width: x + 4

A = l * w

A = (2x + 1)(x + 4)

2x^2 + 8x + x + 4

We can add like terms now:

2x^2 + 9x + 4

Our area is 2x^2 + 9x + 4

Our answer would be a(x)=2x^2+9x+4

Which three lengths could be the lengths of the sides of a triangle?

natali 33 [55]

Answer:

D. 15 cm, 9 cm, 24 cm

Step-by-step explanation:

The three lengths that could be the lengths of the sides of a triangle, must satisfy the following condition;

---sum of any two smaller sides chosen must be equal to the third side.

Test option A : 6 cm + 11 cm = 17 cm ( 17 cm ≠ 23 cm)

Test option B: 10 cm + 15 cm = 25 cm (25 cm ≠ 24 cm)

Test option C: 6 cm + 6 cm = 12 cm (12 cm ≠ 22 cm)

Test option D: 15 cm + 9 cm = 24 cm (24 cm = 24 cm) ---correct option.

Thus, the three lengths that could be the lengths of the sides of a triangle are 15 cm, 9 cm, and 24 cm

Madison is buying a $3,000 car at 9% simple interest for 2 years. What will be the total amount she pays for the car?

OverLord2011 [107]

Answer:

The correct answer is D. $ 3,540

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of the loan = $ 3,000

Interest rate = 9% annual simple interest = 0.09

Years to pay the loan = 2 years

2. What will be the total amount she pays for the car?

Total amount Madison will pay for the car = Amount of the loan * [1 + (Interest rate * Number of years)]

Total amount Madison will pay for the car = 3,000 * [1 + 0.18]

Total amount Madison will pay for the car = 3,000 * 1.18

Total amount Madison will pay for the car = 3,540

The correct answer is D. $ 3,540

If DC=6x and DA=4x+18, find the value of x then, find AD

shepuryov [24]

The value of x is 9 and AD is 54.

Step-by-step explanation:

From figure, if DC = AD, we can solve for value 'x'

DC = AD

Given:

DC = 6 x

DA = 4 x + 18

Equating the values of both, we get

6 x = 4 x + 18

6 x - 4 x = 18

2 x = 18

x = 9

So, the value of x is 9. By using this value of x, find AD

AD = 4 (9) + 18

AD = 36 + 18

AD = 54
