Answer:

RS = 6

Step-by-step explanation:

RS² = SU*ST (secant-tangent rule)

Substitute

(x + 6)² = (x + 4 + 5)(x + 4)

(x + 6)(x + 6) = (x + 9)(x + 4)

x(x + 6) +6(x + 6) = x(x + 4) + 9(x + 4)

x² + 6x + 6x + 36 = x² + 4x + 9x + 36

x² + 12x + 36 = x² + 13x + 36

Collect like terms

x² - x² + 12x - 13x = -36 + 36

-x = 0

x = 0

✔️RS = x + 6

Plug in the value of x

RS = 0 + 6

RS = 6

2 dice are rolled. What is the probability that the sum of the numbers rolled is a number greater than or eaqual to 5
Firdavs [7]
2 + 3 = 5 > = 5;
2 + 4 = 6 > =5;
2 + 5 = 7 >= 5;
2 + 6 = 8 >= 5;
3+2 = 5 >= 5;
3 + 3 = 6  >= 5;
3 + 4 = 7  >= 5;
3 + 5 = 8  >= 5;
3 + 6 = 9  >= 5;
4+1 = 5  >= 5;
4+2 = 6  >= 5;
4+3 = 7  >= 5;
4+4 = 8  >= 5;
4+5 = 9  >= 5;
4+6 = 10  >= 5;
5+1 = 6  >= 5;
5+2 = 7  >= 5;
..............

6 + 6 = 12  >= 5;


Number of ways it can happen = 27;

Total number of outcomes = 6*6 = 36;



Probability of an event happening = Number of ways it can happen<span><span> / </span>Total number of outcomes => Probability = 27/36 = 0.75;</span>

Carlos and Lily want to know the combined amount of money they made last week. They both made $12 per hour, but Carlos also made
steposvetlana [31]

Answer:

  • Lily is right

Step-by-step explanation:

<u>Carlos made:</u>

  • 12C + 35

<u>Lily made:</u>

  • 12L

<u>Together they made:</u>

  • 12C + 35 + 12L = 12(C + L) + 35

Lily is right. We don't know what 120 means in Carlos's equation, he should put 12L for Lily.
