Answer:
11
Step-by-step explanation:
Opposite sides are congruent at parallelograms. So x+16 must be equal to 2x+5. Solve the equation;
2x+5 = x+16
x = 11 .
The average of 24+34+32+26+45+38+28= 217/7= 31. the average is 31.
It is 400 because 20x20 is 400
F o g is how it's written with the -3 it means
f(g(-3))=what
so first -3 into g(x)
g(-3)=-4(-3)
g(-3)=12
sub for x in f(x)
f(12)=-3(12)^2-5
f(12)=-3(144)-5
f(12)=-432-5
f(12)=-437
