Which student factored the expression x3 - 7x - x2 + 7 correctly based on their answer below?
1 answer:
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

A.–1.8
Step-by-step explanation:
The answer is: $19.56
4 * $4.89= $19.56
-1/8(2h + 4) + 1/2 = -7/4
-1/4h - 1/2 + 1/2 = -7/4
-1/4h = -7/4
h = -7/4 * - 4
h = 7 <==
$600x06x3= $108.00- the interest and with the $600 it would be $708
