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
Answer:
the answer is 1,944
Step-by-step explanation:
all you have to do is multiply 9 and 18 then whatever you get there then you multiply 162 by 12 and you get the answer
Angle KLM=angleNML=90°
the sum of angles in a triangle is 180°
since: angle2=angle3=x
angle1=angle4=y because
180°-90°-x=180°-90°-x
LA=sides (not bases)
LA=2H(L+W)
H=4
L=11
W=7
LA=2*4*(11+7)
LA=8*18
LA=144
answer is 144 cm^2
