I got 280ft^2. I multiplied the areas by 2 because the opposite sides are equal.
<u>Answer:</u>
Alexia ate
fraction of the 8 sandwiches
<u>Step-by-step explanation:</u>
Total number of submarine sandwiches = 8
She cuts 4 sandwiches into each into
halves
Also she cuts the remaining 4 sandwiches into
halves
lets assume the remain
When Alexia eats 2 pieces of
halves she is eating
so there will will be 12 pieces
If the remaining 4 sandwiches is also divided similarly, then there will be 24 pieces
Thus in 24 pieces Alexia is eating 2 pieces.
Hence the fraction will be 
On Reducing it will be
= 
Answer:
A
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
m(x) = 2(x + 4)² - 8 ← is in vertex form
with vertex = (- 4, - 8 ) → A
AND?!?
