find the following square by using the identities
[tex](2xy + 5y) {?}^{2} [/tex]
Answer:
4x²y² + 20xy² + 25y²
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 2xy ; b = 5y
(2xy +5y)² = (2xy)² + 2*(2xy) * (5y) +(5y)²
= 2²x²y² + 2* 2* 5 * x*y*y + 5²*y²
=4x²y² + 20xy² + 25y²
A baseball stadium holds 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper level. The middle level has 40 more than twice as many seats as the upper level.
x + (2x + 40) + (3x – 50) = 15,002
The upper level has seats.
Answer:
The correct answer is 2,502 seats

A circle has a radius of 6x9y5cm. What is the area of the circle in square centimeters?
12πx11y7
12πx18y10
36πx11y7
36πx18y10
Answer:The answer is the second option: 36πx^18y^10
Step-by-step explanation:
To solve this exercise, you must follow the proccedure below:
1. You have that:
- The formula for calculate the area of the circle is: A=πr² ("r" is the radius of the circle).
-The problem says that the circle has a radius of 6x^9y^5 (r=6x^9y^5)
2. When you substitute r=6x^9y^5 into A=πr², you obtain:
A=πr²
A=π(6x^9y^5 cm)²
3. By applying the exponents properties, you have:
A=36πx^18y^10 cm²

Answer:
Can I be marked brainliest?
x = -1
Step-by-step explanation:
Switch it around
4 - 3x = 7
-3x + 4 = 7
Subtract 4 from both sides of the equation
-3x + 4-4 = 7-4
Simplify
-3x = 3
Divide both sides of the equation by the same term

Triangle QRS has the angle measures shown.
What is the measure of the obtuse angle?
m2Q=(1x)
mZR= (3x)
m25 = (6x)
O 18
54
108
© 216
Answer:
108 degrees
Step-by-step explanation:
Given the following angle measures in triangle QRS
m<Q = 1x
m<R = 3x
m<S = 6x
Note that the largest angle is the obtuse angle since they are always greater than 90 and less than 180 degrees
The sum of angle in a triangle is 180 degrees
m<Q + m<R + m<S = 180
1x + 3x + 6x = 180
10x = 180
x = 180/10
x = 18
The obtuse angle is 6x
Measure of the obtuse angle = 6x
Measure of the obtuse angle = 6(18)
Measure of the obtuse angle = 108 degrees
Hence the measure of the obtuse angle is 108 degrees

write down an expression for the nth term of the following sequence
5, 11, 17, 23, ...
Answer:
[tex]a_{n}[/tex] = 6n - 1
Step-by-step explanation:
There is a common difference d between consecutive terms in the sequence
d = 11 - 5 = 17 - 11 = 23 - 17 = 6
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 5 and d = 6 , then
[tex]a_{n}[/tex] = 5 + 6(n - 1) = 5 + 6n - 6 = 6n - 1

a cinema has three screens last saturday there were 500 visitors
Answer:
200 visitors went to screen 1.
125 visitors went to screen 2.
175 visitors went to screen 3.
Step-by-step explanation:
We will find number of visitors who went to screen 1 by finding 40% of 500 as we are told that 40% of 500 visitors went to screen 1.
Therefore, 200 visitors went to screen 1.
Now we will find number of visitors who went to screen 2. We are told that 25% of 500 visitors went to screen 2.
Therefore, 125 visitors went to screen 2.
Now we will find the number of visitors who went to screen 3 by subtracting combined number of visitors who went to screen 1 and screen 2 from total number of visitors.
Therefore, 175 visitors went to screen 3.

How to find side of triangle ?This free triangle calculator computes the edges, angles, area, height, perimeter, median, and other values, as well as a triangle diagram.
When attempting to find the hypotenuse, we use our two known sides as a and b. It makes no difference which leg is a and which is b. Then we solve for c by squaring a and b and taking the square root of both sides.
Pythagoras theorem: If the sides of a right triangle are hypotenuse, perpendicular, and base, then the square of the hypotenuse side is equal to the sum of the squares of the base and perpendicular.
If leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)If leg b is unknown, then. b = √(c² - a²)For hypotenuse c missing, the formula is. c = √(a² + b²)For given triangle,
AB + BC = AC
2x + 4 + 6x > 18

A weather station on the top of a mountain reports that the temperature is currently 0°C and has been falling at a constant rate of 3°C per hour. If it continues to fall at this rate, find each indicated temperature.
Answer:
-6°C
-15°C
-1.5°C
Step-by-step explanation:
The computation is shown below:
in one hour the temperature falls by 3°C i.e.
= 0 - 3
= -3°C
In two hours
= 2 × - 3°C
= -6°C
In five hours
= 5 × -3°C
= -15°C
in half an hour
= 0.5 × -3°C
= -1.5°C
