Answer:
see explanation
Step-by-step explanation:
A difference of squares is factored in general as
a² - b² = (a - b)(a + b)
(i)
(x + 5)² - 16 ← is a difference of squares, that is
(x + 5)² - 4²
= (x + 5 - 4)(x + 5 + 4)
= (x + 1)(x + 9)
(j)
(x - 4)² - 9 ← is a difference of squares, that is
(x - 4)² - 3²
= (x - 4 - 3)(x - 4 + 3)
= (x - 7)(x - 1)
(n)
(2y + 7)² - y² ← is a difference of squares
= (2y + 7 - y)(2y + 7 + y)
=(y + 7)(3y + 7)

Answers
Answer:
78 degrees
Step-by-step explanation:
Assuming you are talking about a triangle, you would add 28 and 74 to get 102. Then subtract from 180.
28+74=102
180-102=78
Hope this helps :-)
Answer:
Assuming these are angles of a triangle, angel F should equal 78.
Step-by-step explanation:
All angles of any triangle add up to 180 degrees. 180-28-74=78.

For the function f defined by f(x) = 2x^2 – 3x, evaluate: f(x+3)
Answers
Answer:
2x² + 9x + 9
Step-by-step explanation:
To evaluate f(x + 3) substitute x = x + 3 into f(x), that is
f(x + 3) = 2(x + 3)² - 3(x + 3) ← expand (x + 3)² using FOIL
= 2(x² + 6x + 9) - 3(x + 3) ← distribute both parenthesis
= 2x² + 12x + 18 - 3x - 9 ← collect like terms
= 2x² + 9x + 9

A problem states: "There are 2 more horses than cows in a field. There are 16 animals in the field in all. How many horses are there in the field?"
Let c represent the number of cows.
Which equation represents the situation?
c + 2 = 16
2c−2=16
2c + 2 = 16
2(c+2)=16
Answers
Answer: 2c + 2 = 16
Step-by-step explanation:
One group has 2 more than the other.
That means in total, they are the same but + 2.
Only 2c + 2 = 16 represents this.
If 7 liters of petrol cost $14.70, calculate the cost of 15 liters of petrol.
Answers
Hi
7 = 14.70
15= X
so : X = 15*14.70 /7 = 31.5
15 liters of petrol cost 31.5
The cost of 15 liters of petrol if 7 liters cost $14.70 is $31.50
To calculate the cost of 15 liters of petrol if 7 liters of petrol cost $14.70,
First, we will determine the cost of 1 liter of petrol.
From the question,
7 liters of petrol cost $14.70
That is,
7L = $14.70
Then,
1 L = $14.70 ÷ 7
1 L = $2.10
∴ The cost of 1 liter of petrol is $2.10
Now, for the cost of 15 liters of petrol, we will multiply the unit price ($2.10) by 15
That is,
The cost of 15 liters of petrol = 15 × $2.10
∴ The cost of 15 liters of petrol = $31.50
Hence, the cost of 15 liters of petrol if 7 liters cost $14.70 is $31.50

Answers
Answer:
Points N and K are on plane A and plane S.
Point P is the intersection of line n and line g.
Points M, P, and Q are noncollinear.
e2020
Step-by-step explanation:
According to the given diagram of Intersecting planes, Option (1), Option (3), Option (4) are True.
What are planes?A plane is a two-dimensional, flat surface that stretches indefinitely.
When does a point lie on a plane?A point is said to lie on a plane when it satisfies the equation of plane which is ax^3 + bx^2 + cx+ d = 0 and sometimes it is just visible in the figure whether a point is lying on a plane or not.
In Option(1) : Points N and K are lying on the line of intersection of plane A and S and will satisfy the equation of both planes.
In Option(2) : Point P is lying on both planes B and S, but the point M is lying only on plane B, hence this option is wrong.
In Option(3) : It is clearly visible the Point P is the point of intersection of lines n and g.
In Option(4) : It is clearly visible that Points M,P,Q are not lying on the same line, hence they are non-collinear.
In Option(5) : Line d intersects the plane A at point L and not point N, hence this is also wrong.
Hence the correct options are 1,3,4.

Order these numbers from least to greatest. 37.5%, 1/3, 0.3, 40%, 3/5.
Answers
Answer:
0.3, 1/3, 37.5%, 40%, 3/5Step-by-step explanation:
Given the numbers 37.5%, 1/3, 0.3, 40%, 3/5, before we can order the numbers from the least to greatest, we need to first express al the values in percentage.
For 1/3;
= 1/3 * 100
= 100/3
= 33.3%
For 0.3:
= 0.3 * 100
= 3/10*100
= 30%
for 3/5;
= 3/5 * 100
= 300/5
= 60%
Hence the numbers in percentage are . 37.5%, 33.3%, 30%, 40%, 60%
The values from the least to the greatest in terms of percentage is 30%, 33.3%, 37.5%, 40%, 60%
In term of the given values from least to greatest is;
0.3, 1/3, 37.5%, 40%, 3/5

Point O is on line segment NP. Given N P = 4x + 10, NO = 4x, and
OP = x + 5, determine the numerical length of NP.
Answers
Answer:
30
Step-by-step explanation:
Hope this will help:)
The numerical length of line segment NP will be 30 units.
What is a line segment?A line segment in mathematics has two different points on it that define its boundaries.
A line segment is sometimes referred to as a section of a path that joins two places.
Point O is on line segment NP.
Given NP = 4x + 10, NO = 4x, and OP = x + 5.
We know that for a line segment.
PN = PO + ON
4x + 10 = 4x + x + 5
x = 5
Then the numerical length of line segment NP will be
NP = 4x + 10
NP = 4(5) + 10
NP = 20 + 10
NP = 30
Then the numerical length of line segment NP will be 30 units.

Cynthia Besch wants to buy a rug for a room that is 29 ft wide and 30 ft long. She wants to leave a uniform strip of floor around the rug. She can afford to buy 756 square feet of carpeting. What dimension should the rug have?
Answers
Answer:
Dimensions of rug:
Length = 28 ft
Width = 27 ft
Step-by-step explanation:
The given dimensions of the room is:
Length = 30 ft
Width = 29 ft
Area of carpeting = 756 sq ft
Kindly refer to the attached image.
Let the uniform strip around floor is of length = [tex]x[/tex] ft
This [tex]x[/tex] feet will be 2 times along the length and
2 times along the width of room.
So, length of rug = 30 -2 [tex]\times[/tex] [tex]x[/tex] and
Width of rug = 29 -2 [tex]\times[/tex] [tex]x[/tex]
It will be rectangular in shape.
Area of a rectangle is given as:
[tex]A = Length\times Width[/tex]
[tex]756 = (30-2x) (29-2x)\\\Rightarrow 756 = 870 - 118x+4x^2\\\Rightarrow 4x^2-118x+114=0\\\Rightarrow 2x^2-59x+57=0\\\Rightarrow 2x^2-57x-2x+57=0\\\Rightarrow x =1, -\dfrac{57}{2}[/tex]
Negative length not possible.
So,Length of strip, [tex]x = 1\ ft[/tex]
Dimensions of rug:
Length = 30 -2 = 28 ft
Width = 29 -2 = 27 ft
