Answer:

1999 moves are required.

Step-by-step explanation:

Given is - In solving a jigsaw puzzle, a move consists of joining two clusters, including clusters of just one piece.

This means exactly n-1 moves are required to solve a jigsaw puzzle with n pieces.

Here, n = 2000

So, moves will be = 2000-1=1999

Hence. 1999 moves are needed to solve the puzzle.

Solution: As always, try to find a way of looking at the problem that makes the solution simple. In this problem, regardless of the current state of the puzzle, a move consists of combining two clusters into a single cluster. Therefore every move reduces the number of clusters by 1. Since we begin with 2000 clusters (the single pieces) and end with 1 cluster, we need \[2000-1=\boxed{1999}\] moves to complete the puzzle.

What is the distributive property of the GCF of 36 and 45 to rewrite the sum
Nataliya [291]

Answer:

9(4 + 5)

Step-by-step explanation:

The GCF of 36 and 45 is

36: 2 * 2 * 3 * 3

45: 3 * 3 * 5

The GCF of 45 and 36 is 9 (the bolded part)

9(4 + 5) would be how the distributive property would be written. The numbers inside the brackets represent what is not bolded.

Which equations are true? Choose all answers that apply: Choose all answers that apply: (Choice A) A -x +0+(- x) = 0−x+0+(−x)=0m
lora16 [44]

Answer:

(B)-x-(-x) =0

Step-by-step explanation:

<u>Option A</u>

Our equation is: -x +0+(- x) = 0

Left Hand Side:

-x +0+(- x) = -x-x=-2x

($Left Hand Side) $-2x\neq 0$ (Right Hand Side)

<u>Option B</u>

Our equation is: -x-(-x) =0

Left Hand Side:

-x-(-x) =-x+x=0

($Left Hand Side) 0 = 0 (Right Hand Side)

Therefore, the equation in Option B is true.

Find the discriminant, and determine the number of real solutions. then solve 2x^2+3x-9=0
LekaFEV [45]
Discriminant = 
b² - 4ac

3² - 4(2)(- 9)
9 + 72
81

Your equation has two real solutions.

2x² + 3x - 9 = 0
2x² + 6x - 3x - 9 = 0
2x(x + 3) - 3(x + 3) = 0

(2x - 3)(x + 3) = 0

Set each equal to zero:

2x - 3 = 0
2x = 3
x = 3/2

x + 3 = 0
x = - 3

Your two solutions are x = - 3, 3/2
