Answer:
2(2n² + 2n) + 1
Step-by-step explanation:
(2n + 1)² can also written as
(2n + 1) × (2n + 1)
= 4n² + 2n + 2n + 1
= 4n² + 4n + 1
= 2(2n² + 2n) + 1
= an odd

Area of frame=area of total-area of inside ting
area=lenght times width
so
inner one
length is 16-2-2 (both sides) or 12
width or height is 9-2-2=5
so area is 12 times 5=60
outter one
16 by 9
16 times 9=144
so
outer-inner=144-60=84
so 2nd option
She didn’t multiply -1/4 by 12 in order to get -1/4x + 3 = -1
which would change her answer, because then you have to subtract 3 from -1 and get -4. Then divide -1/4 & get 16. It changed to positive because of the division & multiplication rule with two negative numbers.
Hope this helps.
