Its a square, so all the sides are equal. Also, since the area of a square (rectangles) is equal to the height times the length, which are both the same, the area of the square is equal to x², where x is the length of any one side of the square, x²=256. now you square root both sides of that equation, x=√256, and the square root of 256 is 16.

Tl;Dr: each side is 16 feet long.

Factorize x3 -2x2 -5x+6

Advocard [28]

Answer: x³-2x²-5x-6=(x-1)*(x-3)*(x+2).

Step-by-step explanation:

$x^3-2x^2-5x+6=\\\\x^3-2x^2+x-x-5x+6=\\\\(x^3-2x^2+x)-6x+6=\\\\x*(x^2-2x+1)-6*(x-1)=\\\\x*(x-1)^2-6*(x-1)=\\\\(x-1)*(x*(x-1)-6)=\\\\(x-1)*(x^2-x-6)=\\\\(x-1)*(x^2-x-2x+2x-6)=\\\\(x-1)*(x^2-3x+2x-6)=\\\\(x-1)*(x*(x-3)+2*(x-3))=\\\\(x-1)*(x-3)*(x+2).$

Ginny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. Whe

svp [43]

Answer:

Step-by-step explanation:

This is exponential, of the form

$y=a(b)^x$ where a is the initial amount and b is the growth/decay rate. If Ginny begins the study with 1200 frogs in the population, our a value is 1200.

If the population is decreasing 3% per year, it is decreasing 100% - 3% = 97% which, as a decimal, is .97. Our exponential function, then, is

$y=1200(.97)^x$

Uber charges a $5 pickup fee and $0.25 per mile. define variables and write an equation to model this situation.

Degger [83]

Answer:

See below

Step-by-step explanation:

$5 pickup fee
$0.25 per mile

<u>Equation</u>

y = 0.25x + 5

<u>Cost of 5 miles:</u>

y = 0.25(5) + 5 = $6.25

<h3>KC yellow Cab Co.</h3>

$1.75 pickup fee
$0.75 per mile

<u>Equation</u>

y = 0.75x + 1.75

<u>Cost of 5 miles:</u>

y = 0.75(5) + 1.75 = $5.5

Comparing the cost we see KC yellow Cab Co. is better value for a 5 mile ride.
