If f(x) = 7x + 4 and g(x) = (x+4,
what is (fº)?
enter the correct answer.

11

Step-by-step explanation:

Evaluate g(- 3) then use this value to evaluate f(x)

g(- 3) = = = 1, then

f(1) = 7(1) + 4 = 7 + 4 = 11

Shania is correct.

Step-by-step explanation:

For a right angled triangle, given two sides and an angle, we can use the sine rule or the various trigonometry identities to solve the triangle;

a/sin A = b/sinB

and

sin (angle) = opposite side/hypotenuse

cos (angle) = adjacent side/hypotenuse

tan (angle) = opposite/ adjacent

assuming a is the opposite side of angle A and b is also opposite of angle B

Otherwise, the only way to solve a triangle given two sides only is by the use of the Pythagoras theorem.

Hence, Shania is correct.
