First, note that 1 meter is equal to 3.28084 feet.
Next, multiply
2000 m • 3.28084 = 6561.68 ft
Divide the total centimeters by centimeters per inch:
51.78 / 2.54 = 30.386 inches.
Answer:
To solve for n you need to get it by itself
First you want to distribute your 2 through the (3n+14)
-2n+6n+28=-20 (2*3n+2*14= 6n+28)
Now you want to combine any like terms if possible
4n+28=-20 (-2n+6n=4n, both like terms)
Then you want to subtract -28 from both sides
4n=-48 (28-28=0, -20-28=-48)
Lastly you want to divide both sides by 4
n=-12 (4n/4=n, -48/4= -12)
y=x^2-2x-15 (1) y=8x-40 (2)
8x-40=x^2-2x-15
X^2+10x-25=0
(x-5)^2
×=5 y=0
The product of 15 and

is

. This is a linear binomial.

is a cubic trinomial. In your original question, I'm not sure what the

means.
