Answer:3x^3(3x^3+2x+5)
Step-by-step explanation:by looking at the polynomial, you can see that all three shares the variable x. Since 9,6, and 25 all share the GCF of 3, you can factor it out. Since the smallest x value of the polynomial is x^3, that is the x value you want to factor out. Since if you factor out x^3 then 15x^3 would not have a variable anymore.
8q² + 4qm + 6q + 3m
4q(2q) + 4q(m) + 3(2q) + 3(m)
4q(2q + m) + 3(2q + m)
(4q + 3)(2q + m)
Let
x------> <span>speed on the bicycle
y------> </span><span>speed walking
we know that
</span>x=6+y------> equation 1<span>
speed=distance /time-------> time=distance/speed
1/y=2.5/x-------> y=x/2.5------> x=2.5y-------> equation 2
equals 1 and 2
6+y=2.5y-----> 2.5y-y=6------> 1.5y=6-----> y=6/1.5-----> y=4 mi/h
x=6+y-----> x=6+4-----> x=10 mi/h
the answer is
the speed walking is 4 mi/h
