A circular running track is 1/4 of a mile long Elena runs this track completing each lap in 1/20 of an hour what is her speed

PSYCHO15rus [73]

Answer:

The speed is equal to $5\frac{mi}{h}$

Step-by-step explanation:

we know that

The speed is equal to divide the distance by the time

Let

x------> the distance in miles

y-----> the time in hours

s----> the speed in mph

$s=\frac{x}{y}$

In this problem we have

$x=(1/4)\ mi$

$y=(1/20)\ h$

substitute

$s=\frac{(1/4)}{(1/20)}=20/4=5\frac{mi}{h}$

Which is a factor of x^2-9x+14?<br> A. X-9<br> B. X-2<br> C. X+5<br> D. X+7

sukhopar [10]

Answer : B

x^2-9x+14

Lets factor $x^2-9x+14$

We find out two factors whose product is +14 and sum is -9

Two factors are -2 and -7, we split the middle term -9x using -2 and -7

$x^2-2x-7x+14$

Group first two terms and last two terms

Then factor out GCF from each term

$(x^2-2x)(-7x+14)$

$x(x-2)-7(x-2)$

$(x-2)(x-7)$

so x-2 is one of the factor
