Write a polynomial in standard form that represents the area of the shaded region.
A rectangle. Its length is labeled 2 x minus 9 and its width is labeled x plus 5.
Answers
Answer:
2x²+x-45
Step-by-step explanation:
In standard form the area of the rectangle is -
A = (2x² + x - 45) square units.
What is function?A function is a relation between a dependent and independent variable. We can write the examples of functions as -
y = f(x) = ax + b
y = f(x, y, z) = ax + by + cz
Given is to write a polynomial in standard form that represents the area of the shaded region which is rectangle whose length is labeled (2x - 9) and its width is labeled (x + 5).
We can write the area of the rectangle as -
A = (2x - 9)(x + 5)
A = 2x(x + 5) - 9(x + 5)
A = 2x² + 10x - 9x - 45
A = 2x² + x - 45
Therefore, in standard form the area of the rectangle is -
A = (2x² + x - 45) square units.

The height of the plant is 76 cm after 24 months.
Step-by-step explanation:
Given;Plant height (H) was already 52 cm tallIt increases 1 cm each month (m)H = 52 + mTo Find;Plant's height after 24 monthsHere, we know that on each month 1 cm every month so it's increased 24 cm after 24 months
Therefore
H = 52 + m
H = 52 + 24
H = 76 cm
Thus, The height of the plant is 76 cm after 24 months.
Which of the following sets of points are vertices of a right triangle?

2) A(-2, 2), B(1, -4), C(4, 2)
3) A(-1, 1), B(3, 5), C(4, -4)
4) A(-1, 3), B(-4, -3), C(-4, 1)
Answers
I scanned for a pair of x coordinates that match and a pair of y coordinates that match. That would be a right triangle whose sides are parallel to the axes. It's possible our right triangle is more complicated, but let's start here.
Nope, it doesn't look like our right triangle is oriented to the axes. Let's do the Pythagorean Theorem.
1) A(-1, -3), B(4, -3), C(2, -1)
AB² = (4 - -1)² + (-3 - -3)² = 25
AC²= (2 - -1)² + (-1 - -3)² = 9 + 4 = 13
BC²= (2 - 4)² + (-1 - -3)² = 4 + 4 = 8
25 ≠ 13 + 8, not a right triangle
2) A(-2, 2), B(1, -4), C(4, 2)
AB² = (-2 - 1)² + (-4 - 2)² = 9 + 36 = 45
AC²= (4 - -2)² + (2 - 2)² = 36
BC²= (4 - 1)² + (2 - -4)² = 9 + 36 = 45
not a right triangle, but isosceles
3) A(-1, 1), B(3, 5), C(4, -4)
AB² = 4² + 4² = 32
AC²= 5² + 5² = 50
BC²= 1² + 9² = 82
BC² = AC² + AB², THIS IS A RIGHT TRIANGLE
4) A(-1, 3), B(-4, -3), C(-4, 1)
AB² = 3² + 6² = 45
AC²= 3² + 2² = 13
BC²= 0² + 4² = 16
not a right triangle
Answer: 3) A(-1, 1), B(3, 5), C(4, -4)
The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.
The side lengths of a triangle area are 5, 3, and 4. Is this a right triangle?

4² = 16
5² = 25

9 + 16 = 25

Hope this helps. Have a nice day.
Answer:
C.)Yes because \(3^{2} + 4^{2} = 5^{2}\)
Step-by-step explanation:
The Pythagoras theorem should be applied in this question. This theorem can only be applicable if the triangle has a right angle ( 90° ) therefore it is used.
\(a^{2} + b^{2} = c^{2}\) (The Pythagoras theorem)
\(3^{2} + 4^{2} = 5^{2}\)
\(3^{2}\) = 9 and \(4^{2}\) = 16. So,
9 + 16 = 25 and \(5^{2}\) = 25
∴ The sides proves that it is a right angled triangle.

how can you find the product of positive and negative decimals
Answers
(I have attached an example for reference)
1) Product means multiply, so we will multiply the decimal numbers.
2) First multiply both the numbers just the way you multiply two whole numbers.
3) note that WHILE multiplying you DON'T put the decimal point. Put the decimal point once you get your FINAL answer.
4) Once multiplied, count the total number of places after the decimal in both the numbers which were given. i.e, in the example it's 2 decimal places, one decimal place in 24.5 and one in 3.2, which means the total decimal places here are two.
5) now in your answer, start counting the decimal places from the right side of the number. For example in 7840, we start counting two decimal places from the right side of it and stop at 4 and put a decimal point there. This way we get 78•40.

Answer:
Area of five squares = 1289.09 square units
Perimeter = 194.6 units
Step-by-step explanation:
Area of square and perimeter:
First find the length of each square, then find the area of each square.
To find the area of five squares, add all the area of each square.
Side of square1 = 27 units
\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)
Area of square1 = 27*27 = 729 square units
Area of square2 = 18*18 = 324 square units
Area of square3 = 12*12 = 144 square units
Area of square4 = 8*8 = 64 square units
Area of square5 = 5.3*5.3 = 28.09 square units
Area of five squares = 729 + 324 + 144 + 64 +28.09
= 1289.09 square units
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)
= 90 + 42 + 28 + 18.7 + 15.9
= 194.6 units
the perimeter is 194.6 units
