Answer:
b² - 121
Step-by-step explanation:
(b +11)(b - 11)
b² - 11b + 11b - 121
b² - 121
When I transfer all those fractions into a fraction with a denominator of 18, I get 30.5/18. From there, a little more math is needed however.
A is quadratic function
B is equation of a circle
C is equation of a line
D is hiperbolic funciotn
Answer:
40.5
Step-by-step explanation:
Since QS is an angle bisector then PQs and SQR are similar. Using the similarity theorem;
PQ/PS = QR/SR
45/20 = x/18
Cross multiply
20x = 45 * 18
20x = 810
x = 810/20
x = 40.5
Hence the value of x is 40.5
