Let f(x) = -2x-1 and g(x)=x^2 + 3.
find (fog)(0)

25/14 or 1.

step-by-step explanation:

the dots mean that it has infinitely more numbers behind it

just get this app called photo math it should be able to do those

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus

32.5 is the answer i got thats the answer
