Factor.
x^2 4x +4
(x + 2)^2
(x+4)^2
(2 – 2)^2
(2 – 4)^2
Answer: The answer is [tex](x+2)^2[/tex]
Step-by-step explanation:
Because [tex](x+2)^2[/tex] means [tex](x+2)(x+2)[/tex]
So we use the foil method to factor
First: [tex]x*x=x^2[/tex]
Outside: [tex]x*2=2x[/tex]
Inside: [tex]2*x=2x[/tex]
Last: [tex]2*2=4[/tex]
So we now write the following equation [tex]x^2+2x+2x+4[/tex]
Simplfied [tex]x^2+4x+4[/tex]
The sum of two trinomials is 7x2 - 5x + 4. if one of the trinomials is 3x2 + 2x - 1, then what is the other trinomial?
a.
10x2 - 3x + 3
b.
4x2 - 7x + 5
c.
10x2 + 7x + 5
d.
4x2 - 3x + 3
Answer:
b. 4x^2 -7x +5
Step-by-step explanation:
When you know a sum and one of its contributors, you can find the other by subtraction. The other trinomial is ...
(7x^2 -5x +4) - (3x^2 +2x -1)
= (7 -3)x^2 +(-5 -2)x +(4 -(-1))
= 4x^2 -7x +5 . . . . . matches B

The graph of polygon FGHI has coordinates F(2. – 1), G(5,2), H(8, 3), and I(6, 0). Graph the image of FGHI
after a reflection across the line y = -1.
Part A
Graph the line of reflection
Part B
Graph FGHI and its reflection across the line y = -1
Reflecting the polygon FGHI across the line involves flipping the line across the line y = -1
How to reflect the polygon?The coordinates are given as:
F(2, – 1), G(5,2), H(8, 3), and I(6, 0)
The line of reflection is given as:
y = -1
To reflect the line, we apply the following rule of reflection
(x,y) [tex]\to[/tex] (x,-y-2)
So, we have the following coordinates of the image
F' = (2, – 1)
G' = (5,-4)
H' = (8, -5)
I' = (6, -2)
See attachment for the image of the reflected polygon

What is the area of a circle with a diameter of 4x? Please I need help rn
Answer:
12.57x² units²
Explanation:
area of circle: πr² ["r" denotes radius]
diameter: 2r
Given,
diameter: 4x
radius: 4x/2 = 2x
Area of circle:
πr²
π(2x)²
π(4x²)
4πx²
12.57x²
Answer:
4πx² square units
Step-by-step explanation:
Area of a circle
[ A = πr² ]The formula uses the radius of the circle, but we have the diameter. Remember the relation :
Diameter = 2 x Radius4x = 2 x RadiusRadius = 4x/2 = 2xNow, we can solve.
⇒ A = πr²⇒ A = π(2x)²⇒ A = 4πx² square unitsComplete the steps to evaluate log798, given log72 ≈ 0.356. how can you rewrite log798 using the product property?
The expression [tex]\rm log_{7} 98[/tex] using the product property is [tex]\rm log_{7} 49 + \rm log_{7} 2[/tex].
What is a logarithm?A logarithm is the exponentiation inverse function that can be expressed by the exponent or power to which a base must be raised to yield a number.
It is given that [tex]\rm log_{7} 2[/tex] = 0.356
We can write [tex]\rm log_{7} 98[/tex] in terms of [tex]\rm log_{7} 2[/tex]
[tex]\rm log_{7} 98[/tex] = [tex]\rm log_{7} (49\times 2)[/tex]
In logarithm, the product will change in addition
[tex]\rm log_{7} 98[/tex] = [tex]\rm log_{7} (49\times 2)[/tex]
= [tex]\rm log_{7} 49 + \rm log_{7} 2[/tex]
Hence, the expression [tex]\rm log_{7} 98[/tex] using the product property is [tex]\rm log_{7} 49 + \rm log_{7} 2[/tex]

The measure of an angle is eighty-nine times it's supplementary angle. what is the measure of each angle.
I need two answers,
Answer:
178 and 2
Step-by-step explanation:
sum of supplementary angles are 180
so, x+ 89x = 180
=> x+89x = 180
=> 90x = 180 [the transposing method]
=> x = 180/90
=> x = 2
now we have the value of one angle
as the other angle is 89 times x,
=> 89x
=> 89*2
=> 178
now, we have the measure of both the angles which equals 180 degree
178 degree and 2 degree

The deck off the back of the house creates a right triangle. The side of the deck resting against the house is the hypotenuse of the triangle. You decide to put new stain on the wood. One edge of the deck measures 15 feet and the other edge of the deck measures 20 feet. Answer the follow- ing questions: 1. What is the area of the deck? 2. Each gallon of stain covers a maximum of 350 square feet. How many do you need? 3. If each gallon costs $36.98, what will the project cost you?
Approximately 2 gallons will be needed if each gallon of stain and the project will cost be $73.96 if each gallon costs $36.98
How to find the area of a triangleThe formula for calculating the area of a triangle is expressed as:
A = 0.5bh
where
base = 15feet
height = 20feet
Area of the deck = 20 * 15 * 0.5
Area of the deck is 150 square feet
Number of gallons needed = 350/150 = 2.3
Hence approximately 2 gallons will be needed if each gallon of stain covers a maximum of 350 square feet.
Cost of the two gallons = 36.98 * 2
Cost of the two gallons = $73.96
Hence the project will cost be $73.96 if each gallon costs $36.98

Find the Perimeter of each figure. Show your Solution.
(Note: No Solution considered wrong)
Answer:
1) 40 m; 2) 18 cm
Step-by-step explanation:
1) Length = 10 m
Breadth = 4 m
Perimeter of a rectangle
= length (l) × breadth (b)
= 10 × 4
= 40 m
2) Side 1 = 6 cm
Side 2 = 8 cm
Side 3 = 4 cm
Perimeter of a triangle
= Side 1 + Side 2 + Side 3
= 6 + 8 + 4
= 18 cm
_______
Hope it helps ⚜
Answer:
1. 28m
2. 18 cm
Step-by-step explanation:
Perimeter of rectangle = 2× (length + breadth )
=> 2 ( 10 + 4 )
=> 2 ( 14 )
=> 28 m
Perimeter of triangle = side a + side b + side c
=> 6cm + 8cm + 4cm
