Answer:
2x(x+y)(x-y)
Step-by-step explanation:
Given the expression;
(x+y)² + 2(x+ y)(x- y) + (x– y)²
Factorize
(x+y)² + (x+ y)(x- y) + (x+ y)(x- y) + (x– y)²
= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]
= (x+y)(x-y)(x+y+(x-y))
= (x+y)(x-y)(x+y+x-y)
= (x+y)(x-y)(2x)
hence the expanded form is 2x(x+y)(x-y)

Answer:
a₂₀ = 69
Step-by-step explanation:
The nth term of an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 15 - 12 = 3 , then
a₂₀ = 12 + (3 × 19) = 12 + 57 = 69

The measure of an angle is 34.7°. What is the measure of its supplementary angle?
Answer:
Let the supplementary angle be x.
x+34.7°=180
or, x=180-34.7°
or, x=145.30°
:. x=145.30°
An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment.
Compute the probability of each of the following events.
Event A: The sum is greater than 6.

What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
It takes an old printer 8 hours to print all the pictures for the yearbook.
A modern printer can do the same job in 5 hours.
If both work together,
it will take,
x(1/8 + 1/5) = 1
x(8 + 5)/40 = 1
8x + 5x = 40
x = 40/13
x = 3.07
x = approximately 3.1 hours.
Therefore, the work will be done in 40/13 hours.

what is the volume of the rectangular prism
It is all the numbers multiplied together. 135
Answer:
[tex]\Huge\boxed{D.135 cm^3}[/tex]
Step-by-step explanation:
Hello There!
We can find the volume of the figure by using the formula for volume of a rectangular prism
[tex]V=lwh[/tex]
where l = length, w = width and h = height
we are given all of the dimensions so all we have to do is plug in the values
so
V = 3 x 9 x 5
3x9=27
27x5=135
so the volume of the rectangular prism is 135 cm³

James is participating in a 3-mile walk to raise money for a charity. He has received $300 in fixed pledges and raises $13 extra for every mile he walks. Use a point-slope equation to find the amount he will raise if he completes the walk.
Answer: $339
Step-by-step explanation:
Given
The total length of the journey is 10 miles
fixed pledges are $300
variable pledges are $13 per mile
Point slope equation form is
[tex]\Rightarrow y=mx+c[/tex]
Here the total charge corresponds to y and miles walked corresponds to x
So, we can write
[tex]T=13\times m+300[/tex]
where,
[tex]T=\text{Total charge}\\m=\text{miles walked}[/tex]
for 3 miles distance
[tex]\Rightarrow T=3\times 13+300=\$339[/tex]

Use completing the square to rewrite the given function in vertex form. Determine whether the vertex is a maximum or minimum
value. Select the TWO correct answers.
y = x2 + 4x - 10
-
A)
The vertex form is y = (x - 6)2 + 2.
B)
The vertex form is y= 4x + 2)2 - 10.
C)
The vertex form is y = -(x - 2)2 - 6.
D)
The vertex is a minimum value at point (-6,2).
E)
The vertex is a maximum value at point (2.-6).
Answer:
Step-by-step explanation:
The equation as written doesn’t work. Are you sure it is y = x² + 4x - 10, and not
y = -x² + 4x - 10 ?
y = -(x² - 4x) - 10
y = -(x² - 4x + 2²) + 2² - 10
y = -(x-2)² - 6
the vertex is a maximum at (2,-6)

3(x + 1) - 2x = -6 what’s the answer??
Answer:
x=−9
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x+1)−2x=−6
(3)(x)+(3)(1)+−2x=−6(Distribute)
3x+3+−2x=−6
(3x+−2x)+(3)=−6(Combine Like Terms)
x+3=−6
x+3=−6
Step 2: Subtract 3 from both sides.
x+3−3=−6−3
x=−9
(1/2)^x=16^2
Could you please help me with the step-by step? This problem is giving me trouble.
Write both sides as powers of 2. First,
1/2 = 2⁻¹
16 = 2⁴
so the equation can be rewritten as
(1/2)ˣ = 16²
(2⁻¹)ˣ = (2⁴)²
Recall that [tex](a^b)^c=a^{bc}[/tex], so that
2⁻ˣ = 2⁸
The bases are the same, so the exponents must be equal:
