Answer:
(3√2 - √10)/4Step-by-step explanation:
Simplify, rationalize the denominator
√2/(3 + √5) = √2(3 - √5)/(3 + √5) (3 - √5) =(3√2 - √10)/(3² - 5) =(3√2 - √10)/4These two triangles are congruent. Which side of triangle PQR is the same length as AB?

Solve the system by substitution.
-2y - 10 = x
- 10x - y = -14
Answer:
x=2 and y=−6
sorry this is pretty long, I did not know if you needed the steps or not
Step-by-step explanation:
−2y−10=x;−10x−y=−14
Solve−2y−10=x for x
−2y−10=x
−2y−10+−x=x+−x
−x−2y−10=0
−x−2y−10+2y=0+2y
−x−10=2y
−x−10+10=2y+10
−x=2y+10
-x/-1=2y+10/-1
x=−2y−10
Substitute−2y−10 for x in−10x−y=−14
−10x−y=−14
−10(−2y−10)−y=−14
19y+100=−14
19y+100+−100=−14+−100
19y=−114
19y/19=-114/19
y=-6
Substitute−6 for y in x=−2y−10
x=−2y−10
x=(−2)(−6)−10
x= 2
x=2 and y=−6

The table shows the types of movies and the number of DVDs reented by customers at a Red Box in one
Based on the data in the table, what is the probability that a random customer will not rent a drama?
Answer:
A
Step-by-step explanation:
The probability that a random customer will not rent a drama is 4/5. Option B is correct.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
here,
Total number of rented DVDs = 25 + 36 + 52 + 12 = 125
Number of Drama movies = 25
The probability that a random customer will rent a drama.
P(D) = 25 / 125 = 1/5
Now,
The probability that a random customer will not rent a drama,
P(D)' = 1 - P(D)
= 1 - 1/5 = 4/5
Thus, the probability that a random customer will not rent a drama is 4/5. Option B is correct.

Answer:
10000
Step-by-step explanation:
to know if this answer is correct you have to know the rounding rules:
If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up. Example: 38 rounded to the nearest ten is 40.
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down. Example: 33 rounded to the nearest ten is 30.

Which one doesn't belong? Explain your reasoning
Answer:
A does not belong
Step-by-step explanation:
A does not belong because it is the only option with parallel lines. All other answer options have lines that intersect with eachother.
Answer:
The answer that they're looking for is A. The first set doesn't belong because it's the only one in which the lines are parallel.
However, one could argue that none of the others belong;
B is the only one with two lines instead of 3
C is the only one with three lines converging at the same point.
D is the only one with more than one point of intersection
But it is pretty clear that the answer sought is A. It's the only one with parallel lines.

A water tank already contains 55 gallons of water when Brian begins to fill it. Water flows into the tank at a rate of 8 gallons per minute.
Write a linear equation to model this situation.
-40 =-5y + 8x
x-intercept:
y-intercept:
Answer:
Y Intercept = (0,8)
x Intercept = (-5,0)
Step-by-step explanation:
Rearrange to y=mx+c
-5y= -40-8x
-5y=-8x-40
Divide both sides by -5
y=8/5x+8
Y Intercept = (0,8)
X intercept; Find x when Y=0
0= 8/5x+8
8/5x = -8
x= -5
Hence;
X Intercept = (-5,0)
