If (x^2 – 4) ÷ (x + 2) = x – 2, which polynomial should fill in the blank below?(x + 2) ´ ______ = x^2 – 4

A. x^2 – 4
B. x – 2
C. x + 2
D. x^2 – 2

Answers

Answer 1
Answer:

Option (b) (x-2) is the correct answer.

A polynomial is an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).

So, (x+2)*(x-2)

     =x^(2) -2x+2x-4

     =x^(2) -4

Therefore, LHS is equal to RHS.

Hence, (x-2) is the polynomial that should be filled in that place.

Sam takes out a $167,000 mortgage for 20 years. He makes monthly payments and at the end calculates that he has paid $240,141 towards the mortgage. What is the approximate APR?3%
4%
6%
7%

Answers

Answer:

About 3%

Step-by-step explanation:

3% of $167,000 is $5,010

5010 times the 20 years is 100200 add that to the 167000 and you get $267,200

The actual answer is about 2.4% but 3% is the closest.

Solve for all possible values of x. square root of the quantity x minus 9 end quantity plus 4 equals 8

a) x = −5
b) x = 7
c) x = 13
d)x = 25

Answers

Answer:

Option d)  x = 25

Step-by-step explanation:

we have

√(x-9)+4=8

Solve for x

Subtract 4 both sides

√(x-9)+4-4=8-4

√(x-9)=4

squared both sides

(x-9)=(+/-)4^2

(x-9)=(+/-)16

Adds 9 both sides

x=9(+/-)16

x1=9(+)16=25

x2=9(-)16=-7

Verify

1) For x=25

√(25-9)=4

√(16)=4

4=4 ----> is true

therefore

x=25 is a solution

2) For x=-7

√(-7-9)=4

√(-16)=4

The radicand cannot be a negative number

therefore

x=-7 is not a solution

david is comparing the fractions 2/3 and 3/5. which shows yhe fractions correctly rewritten and compared with the same numerator?

Answers

10/15 and 9/15. To make the numerators the same, you multiply them together to find the Least common multiple and then you multiply the denominator by the same amount you did the numerator.

Answers

21/3 = 7        21/6 = 3.5
18/3 = 6        18/6 = 3
24/3 = 8        24/6 = 4
12/3 = 4        12/6 = 2

Each can be divided to obtain an integer, except:

21/6 = 3.5

So, while 21 can be divided by 3, it cannot be divided by 6 (for an integer anyway)
21/3=7
but
21/6=3.5
