Answer:
well when you hear "union" you think 'joined' or 'together' since thats what it means, In a mathmatical set of numbers, union means that both of the sets are necessary for the equation to be true. I'm not sure what the sets are in this problem but in order to get "union" from anything, that means that when you checked for your domains, the values that you got had to be part of both the given sets

a school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long. Which patio has a greater area?
Answer:
The 21' by 21' square patio is larger by 9 square feet
Step-by-step explanation:
[tex]24 \times 18 = 432[/tex]
[tex] {21}^{2} = 441[/tex]
The square patio will have more area than the rectangular one.
What is an area?
The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
Given that the school has 2 large patios. one is rectangular and is 24 feet long by 18 feet wide. The other is square and each side is 21 feet long.
The area of the rectangle is calculated as,
Area = L x W
Area = 24 x 18
Area = 432 square feet
The area of the square is calculated as,
Area = S²
Area = (21)²
Area = 441 square feet
The area of the square is greater than the area of the rectangle.

Answer:
B (same slope, lower starting point)
Step-by-step explanation:
The slope on this graph is 5, and the slope of y=5x+5 is 5, so the slopes are the same.
This graph has a y-intercept of -6, which is lower than y=5x+5's intercept of 5, so it starts lower, so B.

if a ferry boat covers 28 miles in 4 hours how much distance will it cover in 12 hours?
Answer:
84 miles in 12 hour
Step-by-step explanation:
12/4 = 3
3*28=84
Answer:
84 miles.
Step-by-step explanation:
First, find the rate of miles travel per hour. It is given that the boat covers 28 miles in 4 hours. Simply divide 28 with 4:
28/4 = 7
The boat covers 7 miles per hour.
Now, multiply 12 hours with 7:
12 hours x 7 miles per hour = 84 miles per 12 hours.
84 miles is your answer.

Answer:
[tex]n=5/2[/tex]
Step-by-step explanation:
We have the equation:
[tex]5^{2n-2}=125[/tex]
Notice that 125 is the same as 5³. So:
[tex]5^{2n-2}=5^3[/tex]
Since they have the same base, the exponents must be equal. Therefore:
[tex]2n-2=3[/tex]
Solve for n. Add 2 to both sides:
[tex]2n=5[/tex]
Divide both sides by 2:
[tex]n=5/2=2.5[/tex]
So, the value of n is 5/2.
And we're done!
Answer:
N = 2.5
Step-by-step explanation:
Ok, so try this.
125 is 5^3, right?
And in this equation, we have 5 to the power of 2n-2 is equal to 125.
You need to make sure that the exponent ends up as 3.
How would you do this?
Try substituting N for 3.
That's too big.
Try Substituting N for 2.
That's a bit too small.
What number is in between 2 and 3?
2.5 is.
N = 2.5
Check your work, and see if you came up with the same answer
Work:
2.5 x 2 = 5
5 - 3 = 2
5^3 = 125

#25 is x+79°=79
2x-37°=-37
#26 is 3x+71°=71
5x+37°=37
Step-by-step explanation:
how you ask because when it is like x+55° and 6x+88° that means its going to be a positive number.
but when it is like 5x-78° that means its going to be a negative number.
remember this +=positive and -=negative

2+3/4x=5/12
Rewrite the equation so that it does not have any fractions
Answer:
24+9x=5
Step-by-step explanation:
First you need to find the least common multiple of the denominators of the fractions. In this case, it would be 12. Then, multiply the entire equation by this number.
2*12=24,
3/4*12=36/4=9,
5/12*12=60/12=5.
Using these values will give your final equation: 24+9x=5
