Answer:

24.5

Step-by-step explanation:

Because the figure is a parallelogram, the opposite sides are equal in length.

1. Set the equations equal to each other:

JK = LM ⇒ 7x = 3x+14

2. Subtract 3x from both sides

7x = 3x+14

- 3x - 3x

___________

4x = 14

3. Divide both sides by 4

(1/4)4x = (1/4)14 ⇒ x = 3.5

4. Plug the value of x into the equation of JK

JK = 7x ⇒ JK = 7 (3.5)

5. Multiply

JK = 24.5

Add. 2.60 3.56 3.82 5.116 5.16 6.16

UNO [17]

2.60 + 3.56 = 6.16

6.16 + 3.82 = 9.98

9.98 + 5.116 = 15.096

15.096 + 5.16 = 20.256

20.256 + 6.16 = 26.416

The final answer is 26.416

Factor x3 + x2 + x + 1 by grouping. What is the resulting expression? (x2)(x + 1) (x2 + 1)(x) (x2 + 1)(x + 1) (x3 + 1)(x + 1)

yanalaym [24]

Answer : $(x^2 + 1)( x + 1)$

Factor $x^3 + x^2 + x + 1$ by grouping

We group first two terms and last two terms

$(x^3 + x^2)+( x + 1)$

Now we take out GCF from each group

GCF of $(x^3 + x^2)$ is x^2

GCF of $+( x + 1)$ is 1

$(x^3 + x^2) +( x + 1)$

$x^2(x + 1) +1( x + 1)$

Now we factor out x+1 that is in common

$(x^2 + 1)( x + 1)$

sergeinik [125]

Question:

Instructions for a craft project say that the length of a piece of red ribbon should be 7 inches less than the length of a piece of blue ribbon.

How long is the red ribbon if the length of the blue ribbon is:

10 inches?

27 inches?

x inches?

Answer:

a) Length of red ribbon is 3 inches

b) Length of red ribbon is 20 inches

c) Length of red ribbon is (x - 7) inches

Solution:

Given that,

The length of a piece of red ribbon should be 7 inches than the length of a piece of blue ribbon

Therefore,

Length of red ribbon = length of blue ribbon - 7 ---- eqn 1

We have to find the length of red ribbon if the length of the blue ribbon is:

a) length of blue ribbon = 10 inches

Therefore, from eqn 1,

Length of red ribbon = 10 - 7

Length of red ribbon = 3

Thus length of red ribbon is 3 inches

b) length of blue ribbon = 27 inches

Therefore, from eqn 1,

Length of red ribbon = 27 - 7

Length of red ribbon = 20 inches

c) length of blue ribbon = x inches

Therefore, from eqn 1,

Length of red ribbon = x - 7

Thus length of red ribbon is (x - 7) inches
