Answer: The correct option is c.
Explanation:
Reason for correct option:

This expression cannot be factored further because
is the complete factor. Therefore the option c is correct.
Reason for incorrect option:

Since the given expression can be factored further therefore the option d is incorrect.

Since the given expression can be factored further. Therefore the option a is incorrect.

Since the given expression can be factored further. Therefore the option b is incorrect.
Answer:
a=120
b=240
Step-by-step explanation:
if x=12
a=5×2×2×2(x-5)
5×2=10×2×2=40
40(x-5) 40x-200
200=40×\40x=5
b=2×10×12=240
a=120
b=240
Answer:
the answer is d
Step-by-step explanation:
the answer is d because
1 worker=1/5 grass per hour
6 workers
number of workers times work each worker does times time needed=total work done
5 times ? times 1=1 lawn
?=1/5 lawn
1 worker does 1/5 lawn in 1hour
6 workers
work is 1/5
time=?
total work=1
6 times 1/5 times ? =1
6/5 times ?=1
times 5/6 both sides
?=5/6
it takes 5/6 hour or 50 minutes
