It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.
Convert 7 to a fraction with 5 on the bottom
35/5+2/5= 37/5 or 7.4
Answer:

The sequence is probably ×2
Answer:
37
Step-by-step explanation:
f(x) = 2x-1
g(x) =x^2 +3
f°g(x) = means put g(x) in for x into the function f(x)
f(g(x)) = 2 (g(x)-1
=2(x^2 +3) -1
Distribute
= 2x^2 +6-1
=2x^2 +5
Now we let x=-4
f(g(-4)) = 2 (-4)^2 +5
=2(16) +5
=32+5
=37
