Answer:
x = -3
i explained it in the picture
Since the angle they have to equal is 97 the answer is 12
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
138.. cause there is 18 ones that makes one ten.. and 8 left over.. so then you will have 1 hundred, 3 tens, and 8 ones.
Jake because 45.21×10=452.1 which is not a whole number, and 8.22×10=82.2 which is also not a whole number, but 45.21×100=4521 which is a whole number, and 8.22×100=822 which is also a whole number. When you multiply a number with 1 and 0s behind it (ex: 10,100,1000, etc) You just more the decimal place the number of 0s you have (ex: 2.0×100= 200, 3.5×1000=3500)
