An ostrich can run 25 miles in 40 minutes. How many minutes will it take the ostrich to run 40 miles if it runs at the same spee

fenix001 [56]

The Ostrich will take 64 minutes to cover 40 miles.

Data;

rate = 25 miles in 40 minute

To calculate the time it will take the ostrich to cover 40 miles, we have to compare it with the rate (speed).

$25mi = 40 min\\40 mi = x min$

Cross multiply both sides

$x * 25 =40 * 40$

simplify the value

$x*25=40*40\\25x = 1600\\$

divide both sides by the coefficient of x

$25x = 1600\\25x/25 = 1600/25\\x = 64$

From the calculations above, it would take the ostrich 64 minutes to cover 40 miles.

Factor this completely<br><br> P(x)=x^4-256

posledela

$\bf p(x)=x^4-256\qquad \boxed{2^8=256}\qquad p(x)=x^{2\cdot 2}-2^{4\cdot 2}
\\\\\\
p(x)=(x^2)^2-(2^4)^2\implies p(x)=[x^2-2^4]~[x^2+2^4]
\\\\\\
p(x)=[x^2-(2^2)^2]~[x^2+2^4]\implies p(x)=[(x-2^2)(x+2^2)]~[x^2+2^4]
\\\\\\
p(x)=(x-4)(x+4)(x^2+16)$
