Answer:

x = 30

Step-by-step explanation:

a^{2} = c^{2} - b^{2}

a^{2} = 50^{2} - 40^{2}

a^{2} = 2500 - 1600

a^{2} = 900

\sqrt{a^{2}} = \sqrt{900}

a = 30

Answer:

30

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem to find the missing side

a^2 +b^2 = c^2  where a and b are the sides and c is the hypotenuse

x^2 + 40^2 = 50^2

x^2 +1600 = 2500

x^2 = 2500-1600

x^2 = 900

Take the square root of each side

sqrt(x^2) = sqrt(900)

x = 30

Consider f(x)=x+7 and g(x)=x^2-1 find (g of f)(x)
finlep [7]

Answer:

g(f(x))=x^2 + 14x + 48

Step-by-step explanation:

you insert (x+7) into every x in the g(x) equation, so g(x)=(x+7)^2 - 1. then you simplify it by doing (x+7)(x+7) which gets you x^2 + 14x + 49. then you subtract the 1 from the equation to get g(f(x))=x^2 + 14x + 48.
