Answer:
AR = 24 units
RB = 25 units
Step-by-step explanation:
In a rectangle:
- Each two opposite sides are equal in length
- The two diagonals are equal in length
- The four angles are right angles
- The length of the diagonal is equal to the square root of the sum of the squares of its two dimensions
In rectangle ABCR
∵ AR and BC are opposite sides
∴ AR = BC
∵ AR = 3x + 6
∵ BC = x + 18
- Equate them to find x
∴ 3x + 6 = x + 18
- Subtract x from both sides
∴ 2x + 6 = 18
- Subtract 6 from both sides
∴ 2x = 12
- Divide both sides by 2
∴ x = 6
Substitute the value of x in the expression of AR to find its length
∵ AR = 3(6) + 6
∴ AR = 18 + 6
∴ AR = 24 units
∵ AC is a diagonal of rectangle ABCR
∴
∵ AR = 24 units
∵ RC = 7 units
∴
∴ AC = 25 units
∵ RB is a diagonal of the rectangle ABCR
∵ The two diagonal of the rectangle are equal in length
∴ AC = RB
∴ RB = 25 units
Answer:
1. Calculate the slope from 2 points.
2. Substitute either point into the equation.
3.Solve for b, which is the y-intercept of the line.
4. Substitute b, -1, into the equation from step 2.

I gave you one extra than what you expected, if thats ok.
Hope this helps : )
Play it again sports / finish line / champs. But all online because corona is taken up the whole world
Answer:
B
Step-by-step explanation:
The answer would be B, because the y-intercept is positive. To double check I used an online graphing calculator and it is correct.
Hope This Helps! Have A Nice Day!!
<span>Experimental probability is not necessary always same. For example, you may flip a fair coin 10 times and you probably would get 6 heads and 4 tails.
Then the experimental probability of getting a head would be 6/10 = 60%.
Now you can do 10 trials again and you probably would get different result such as 5 heads and 5 tails. In this case, the </span>experimental probability of getting a head would be 50%, which is different. Experimental probability depends on a result of actual trials, so it may be different.
Theoretical probability is always same.
Hope this helps.
