If she has 3 times as many quarters as nickels, and nickels are represented by n, you would multiply n by three to get your answer, so your answer is 3n, or D.
Answer:
55.866 ft
Step-by-step explanation:
Use Pythagorean Theorem:
a² + b² = c²
(39)² + (40)² = c²
3121 = c²
Square root of both sides
c = 55.866 ft should be the answer.
Hope this helps
Lets get started :)
These questions have asked us to solve by completing the square.
How do we? I have attached a picture, which will explain
6. x² + 2x = 8
→ b is the coefficient of x, which is 2
→ We take half of 2 and square it. Then, we add it to either side
x² + 2x

x² + 2x + 1 = 8 + 1
( x + 1 )( x + 1 ) = 9
( x + 1 )² = 9
x + 1 = + 3 or x + 1 = - 3 x = 2 or x = - 47. x² - 6x = 16
→ We do the same thing we did in the previous question
x² - 6x +
x² - 6x + 9 = 16 + 9
(x - 3)² = 25
x - 3 = + 5 or x - 3 = - 5 x = 8 or x = - 28. x² - 18x = 19
x² - 18x +

x² - 18x + 81 = 19 + 81
( x - 9 )( x - 9 ) = 100
( x - 9 )² = 100

x - 9 = + 10 or x - 9 = -10
x = 19 or x = - 1
9. x² + 3x = 3
x² + 3x +

or x +
x =

The question is incomplete. Here is the complete question:
What is the volume of this triangular prism?
Base length = 22.4 cm
Height = 18.1 cm
Length = 28 cm
A) 313.6 cm3
B) 506.8 cm3
C) 5,676.16 cm3
D) 11,352.32 cm3
Answer:

Step-by-step explanation:
Given:
The base of the prism is triangular with base length equal to 22.4 cm and height 18.1 cm. The length of the prism is 28 cm.
The volume of a triangular prism is defined by the formula:

Here, the base is triangular and the area of a triangle is:

Therefore, the volume of the triangular prism is given as:

Now, plug in the given values and solve for the volume 'V'.

Therefore, the correct answer is the third option.
