Answer:
31120 ounce
Step-by-step explanation:
We can check the end terms first
for
(a+b)(c+d), the first term of the expanded is ac and the last term is bd
so
the expanded is x^3 and last is +7
jane will have a lst term of -7 so no
mariah wil have last term of -7 as well, so no
only rojer and nethan have last tem of +7
so we can do the rest of it by doing the OL part of FOIL
do either roger or nethan
let's do nethan
F=x^3
O=-7x
I=-x^2
L=7
yep
it is nethan
First, the estimating part. by estimation, you can see, like the problem says, how reasonable your answer is. In this instance, 1035 is close to 1000, and 1000 times 6 is 6000. we should get an answer in this range, and if we don't, we know something's up.
now, to actually solve it
1035 per week* 6 weeks= 1035*6=6210.
It is in the range of 6000, so we can see its reasonable, and a double check ensures it is correct
3 fourths of an hour is : (3/4)
(3/4)*4=3 hours
hope this helps!
Hi,
-7.2 is NOT between -7 and -4 on the number line.
