Answer:
5.4
Step-by-step explanation:
Sum = 11.9
One decimal = 6/5
x = 11.9 - 6.5
= 5.4
Therefore x is 5.4 :)
Answer: x^2+10x+5x+50 = x^2+15x+50
Step-by-step explanation:
Basically, use something called FOIL. It stands for first, outer, inner, last. Basically multiply the first x, by the first x in the second parenthesis. Then multiply that x by the outer x in the second parenthesis. After that, multiply the 5 by the inner x. Then the five by the ten.

Answer:
The answer to your question is the second choice tan Ф = -3/4
Step-by-step explanation:
Data
sin Ф = -3/5
cos Ф > 0
Process
1.- The sin Ф is negative, which means that is in the third or fourth quadrant.
2.- sin Ф = -3/5 and sin Ф = Opposite side/hypotenuse
then, Opposite side = 3 hypotenuse = 5
3.- Calculate the adjacent side using the Pythagorean theorem
c² = a² + b²
b² = c² - a²
b² = 25 - 9
b² = 16
b = 4
4.- If cos Ф is in the third quadrant
cos Ф = -4/5 and cos Ф < 0 This is incorrect
5.- If cos Ф is in the fourth quadrant
cos Ф = 4/5 and cos Ф > 0 This is correct
Then, this angle is in the fourth quadrant
6.- Calculate tan Ф
tan Ф = -3/4
