It’s 14n-44 (n2 and 7n have the same letter so you multiply 2 by 7 then keep the n.)

Answer:

(n−4)(n+11)

Step-by-step explanation:

- Ask yourself what two numbers multiply to give you 44, but add to give you 7. This will be 4 and 11 as shown in answer.

- The reason it is - and then + is because that is one of the factoring rules you will need to learn and follow. I would suggest looking them up.

- Next, seperate the n2 and fill in the problem with the numbers and signs.

- Check your work by multiplying this out.

- Hope this helps! If you need a further explanation or more help please let me know.

16)<br> 1420<br> 2x<br> A) 67<br> C) 68<br> B) 71<br> D) 73<br><br> What is the value of x???
larisa [96]

Answer:

x = 710

Step-by-step explanation:

1. Divide both sides by 2 to get x by itself

1420 = 2x

↓

1420 ÷ 2 = 2x ÷ 2

↓

710 = x

2. Switch sides

710 = x

↓

x = 710

I know it is not one of your options but that is the answer to 1420 = 2x

[(7+3)x5-4](divided by) 2+3<br> SHOW ALL WORK WILL MARK BRAINLIEST
Nesterboy [21]

Answer:

26

Step-by-step explanation:

[(7+3)5-4]/2+3

-To solve this equation you have to use PEMDAS

P- Parentheses

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction-

- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])

Step 1) [(10)5-4]/2+3

- First you do "P," parentheses, so you add 7+3=10

Step 2) [50-4]/2+3

- Next you do "M," multiplication, and multiply 10x5=50

Step 3) [46]/2+3

- Then you do "S," subtraction, and subtract 50-4=46

(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)

Step 4) 23+3

- Now we do "D," division, and divide 46/2=23

Step 5) 23+3=6

- Finally we do "A," addition, and add 23+3=26 so the answer is 26

(FYI: "/" means division)
