Difference is -2(x+6)/(x+4)(x-4)

<u>Step-by-step explanation:</u>

Step 1:

Find the difference between x/x²-16 and 3/x-4

Now x² - 16 = (x-4)(x+4) (using the identity a² - b² = (a+b)(a-b)

⇒ x/x²-16 = x/(x-4)(x+4)

⇒ x/(x-4)(x+4) - 3/x-4 (Subtracting the both to find difference)

= 1/(x-4) [x/x+4 - 3]      (Taking the common factor 1/x-4)

= 1/x-4[x - 3(x+4)/x+4]

= 1/(x-4)(x+4) [x - 3x - 12]

=  1/(x-4)(x+4) [-2x - 12]

= -2(x+6)/(x-4)(x+4)

kali runs 10 laps around a track each day. Each lap around the track is 400 meters. How many will it take kali to run a total of
Flauer [41]

Answer:

3 days

Step-by-step explanation:

Kali runs 10 laps around a track each day, and each lap is 400 meters. So, the first step would be:

10 • 400 = 4,000

That means Kali runs 4,000 meters each day.

Now, there are 1,000 meters in 1 kilometer. This means he runs 4 kilometers each day, and we're trying to get to 12 kilometers.

The final step is to divide. 12/4 = 3

So, it would take 3 days for him to run a total of 12 kilometers.

Mrs johnson grows herbs in square plots Her basil plot measures. 5. 9 yd on each side. A. Find the total area of the basil plot.
UNO [17]

Answer:

Area = 34. 81 yd^2

Perimeter = 86.6 feets

Step-by-step explanation:

Given the following :

Shape of Mrs. Johnson's plot = square

All sides of a square are of equal length

Measure of each side = 5.9 yd

A.) Area of plot

Area of plot = Area of a square

Area of a square(A) = a^2

Where a = side length

A = 5.9^2

A = 34.81 yd^2

B) Perimeter of Basil plot = Perimeter of a square

Converting yard to feet

1 yard = 3feets

Therefore,

5.9 yards = (3 * 5.9) = 17.7 feets

Fence is 2ft from the garden on each side,

Length of fence on each side = (2 + 17.7 + 2) Feets = 21.7 Feets

Perimeter of a square (P) = 4a

Where a = side length

P = 4 × 21.7

P = 86.6 feets

B. Is the right answer

First you have to take the common elements then use an identity/formula to get the rest

x^3 - 3x^2 + x-3
x^2 (x-3) +1 (x-3)
(x^2 +1) (x-3)
(x-1)(x+1)(x-3) {using a^2-b^2 on x^2-1^2}
