Use the expression below.
-4b + 8c + 12 - 8b - 2c + 6
Part A
Simplify the expression.

Part B
Factor the simplified expression using
the GCF.

Part C
What is the value of the expression
when b = 2 and c = -3?

Answers

Answer:

Part A) − 12 b  +  6 c  +  18

Part B) -2b + 1c + 3

Part C) -4

Step-by-step explanation:

Part A)

Step 1:

-4b + -8b = -12b

Step 2:

8c + 2c = 6c

Step 3:

12 + 6 = 18

Answer: − 12 b  +  6 c  +  18

Part B)

GCF = 6

Step 1:

-12 divided by 6 = -2b

Step 2:

6 divided by 6 = 1c

Step 3:

18 divide by 6 = 3

Answer: -2b + 1c + 3

Part C)

Step 1: Subsitute 2 for b and 3 for c

(− 2 x 2 )  +  (1  x -3) +  3

Step 2: Multiply (− 2 x 2 )  +  (1  x -3) +  3

-4 + (-3) + 3

Step 2: Add -4 + (-3) + 3

-7 + 3 = -4

Answer: -4

Anyone with a knee injury or any doctor! What does it mean if my knee popped locked up all in like 1.5 seconds and then it now hurts to bend but not alot and i can wiggle my kneecap like a lot. This is the 2nd time in like 7-9 months! Please help! Comment if there is no more answers left!

Answers

Answer:

Knee pain can have causes that aren't due to underlying disease. Examples include heavy physical activity, lack of use, injuries such as sprains or strains, sitting in a constrained area, or sitting on knees for a prolonged period.

Step-by-step explanation:

possibly Chondro malacia

Damage to the cartilage under the kneecap.

Symptoms may include

Knee pain

Cracking joints

Swelling of the knee

Please go to your doctor...ik it hard with cov id and everything

It could be hereditary, or it could just be a weak muscle. I have knee problems. If it’s just your knee cap that is dislocating you can do simple exercises to strengthen the muscle around it to hold it in place. If it’s your actual knee you should get it checked out to see if there is anything else going on. If it continues and there’s nothing “wrong” they’ll have you do physical therapy. When this dislocation happens, keep your knee up above your heart and ice it. After you pop it back on. And take pain relief. Wear a knee brace as well

Angelique wants to have a rug that is 9 feet long, 7 feet wide. the rug will cover the whole floor except a border that is x feet wide.the area of her room is 167 sq ft. find x

Answers

The width of the border will be about 2.5 feet.

The area of the rug is 9 by 7. Let's call the width of the border x. Therefore, the length of the rug will switch to 9 + 2x. The border is on both sides of it, so we add on 2x. Then, the width is 7 + 2x.

The area of the room is therefore: (9 + 2x)(7+ 2x).

We know the area of the room, so we can write and solve the following equation.

(9 + 2x)(7 + 2x) = 167
4x^2 + 32x + 63 = 167
4x^2 + 32x - 107 = 0

At this point, use the quadratic formula and x will equal about 2.5.
The answer is 2.5 . Hoped this helped

For a school picnic, students are participating in a relay race. Each team has to fill a container that holds 200 liters of water, using bottles that hold 5 liters or 10 liters into the container. So far the blue team has poured ten 5-liter bottles and three 10-liter bottles into the container. How many more 10- liter bottles will the blue team need to fill the container

Answers

Since the blue team already poured ten 5 liters bottles so 10 x 5 = 50
And three 10 liters bottles so 3 x 10 = 30
Now you would add that up , 30 + 50 = 80
Then you subtract it from 200
200 - 80 =120
The last step is to divide by ten since it’s asking how many 10 liters bottles is need to fill the rest
120 divided by 10 =12
The blue team will need twelve 10 liters bottles to fill the container

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 6 rows of the same length, he
has 7 chairs left over. If he arranges the chairs in 4 rows of that same length, he has 13 left over. How many
chairs does Liam have?

Answers

We will need to have two equations here, having x as the missing length. We know that the chairs are in the same amount on each occasion, so each equation should be equal to the other.

This sets up a problem of:

6x + 7 = 4x + 13

7 and 13 being the leftover chairs and 6 and 4 being the rows. Let’s solve for x.

x = 3

Knowing this, we plug in x for one of the equations

6(3) + 7
18 + 7
25

Liam has 25 chairs.

Which number line shows the graph of x≤6
?

Answers

Answer:

C

Step-by-step explanation:

There is a line under the "<" sign which means that "x" can be equal to 6. The arrow going left shows that x is less than 6 and the dot being shaded mean that 6 can be an answer so the number line C is the answer. Hope this helped:)

The required number line that shows the expression x ≤ 6 is figure C. Option C is correct.


What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

What is a number line?

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
The expression x ≤ 6 implies that the domain of the x is a set of a real number less than and equal to 6, so all values represented on the number line below and equal to 6 is bold dark.

Thus, the required number line that shows the expression x ≤ 6 figures C. Option C is correct.
