Answer:
In standard form it is x^4 - 12x^3y + 54x^2y^2 - 108x y^3 + 81y^4.
Step-by-step explanation:
(3y)^4 + 4C1(3y)^3(-x) + 4C2(3y)^2(-x)^2 + 4C3(3y)(-x)^3 + (-x)^4
= 81y^4 - 108y^3x + 54y^2x^2 - 12yx^3 + x^4

1. −4n−8=4(−3n+2)
2. a−15=4a−3
what is the solution for 1 and what is the solution for 2
Answer:
n = 2 and a = - 4
Step-by-step explanation:
(1)
- 4n - 8 = 4(- 3n + 2) ← distribute parenthesis
- 4n - 8 = - 12n + 8 ( add 12n to both sides )
8n - 8 = 8 ( add 8 to both sides )
8n = 16 ( divide both sides by 8 )
n = 2
(2)
a - 15 = 4a - 3 ( subtract a from both sides )
- 15 = 3a - 3 ( add 3 to both sides )
- 12 = 3a ( divide both sides by 3 )
- 4 = a
Find the value of x.
Answer:
x=90°
Step-by-step explanation:
The inside angles in a triangle always add up to 180°.
So:
53°+37°=90°
180°-90°=90°
x=90°
Answer:
see below
Step-by-step explanation:
since the sum of angles in a triangle is 180 degrees
x + 53 + 37 = 180
x = 180 - 53 - 37
x = 90 degrees

Consider the enlargement of the triangle.
A small triangle has a base of 1.7 feet and height of 9.3 feet. A larger triangle has a base of 3.5 feet and height of x feet.
Not drawn to scale
Rounded to the nearest tenth, what is the value of x?
15.8 feet
19.1 feet
23.3 feet
32.6 feet
Given:
After enlargement of the triangle,
Base of small triangle = 1.7 feet
Height of small triangle = 9.3 feet.
Base of larger triangle = 3.5 feet
Height of larger triangle = x feet.
To find:
The value of x.
Solution:
After enlargement the figure is similar to original figure,
We know that the corresponding sides of similar triangles are proportional.
[tex]\dfrac{\text{Base of small triangle}}{\text{Base of larger triangle}}=\dfrac{\text{Height of small triangle}}{\text{Height of larger triangle}}[/tex]
[tex]\dfrac{1.7}{3.5}=\dfrac{9.3}{x}[/tex]
[tex]1.7\times x=9.3\times 3.5[/tex]
[tex]1.7x=33.55[/tex]
Divide both sides by 1.7.
[tex]x=\dfrac{32.55}{1.7}[/tex]
[tex]x=19.1470[/tex]
[tex]x\approx 19.1[/tex]
The value of x is 19.1 feet. Therefore, the correct option is B.

Maria’s phone bills were $95, $67, $43, and $115. What was the mean, or average, of her phone bills?
Answer:
the mean is $80
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
Mean of Phone Bills =
[tex] \frac{phone \: bills \: total}{number \: of \: phone \: bills} \\ = \frac{95 + 67 + 43 + 115}{4} \\ = \frac{320}{4} \\ = 80[/tex]
A wooden building has the shape of a
rectangular pyramid. The building's
base is 100 meters long and 50
meters wide. The height of each
triangular face is 40 meters. How
much wood was used to make the
entire building?
A 33,000 m²
B 13,000 m2
C 11,000 m2
D 6,000 m2
Answer:
B: 13000 m²
Step-by-step explanation:
To find how much wood is used, we will have to find the surface area of the wooden building.
Formula for surface area of a rectangular pyramid is;
SA = lw + l√(h² + w²/4) + w√(h² + l²/4)
We are given;
l = 100 m
w = 50 m
h = 40 m
Thus;
SA = (100 × 50) + 100√(40² + 50²/4) + 50√(40² + 100²/4)
SA = 5000 + 4717 + 3201.56
SA = 12918.56
Approximating to 2 significant figures gives;
SA = 13000 m²
What is the value of the expression below when y=5
4y2-7y-6
Answer and Step-by-step explanation:
Let's plug 5 in for y.
[tex]4(5)^{2} - 7(5) - 6\\\\\\\\4(25) - 35 - 6\\\\\\100 - 35 - 6 = 59\\\\\\[/tex]
The value of [tex]4y^{2} - 7y - 6[/tex] when y is equal to 5 is 59.
#teamtrees #PAW (Plant And Water)
Answer:
59
Step-by-step explanation:
You can just replace y with its value which is 5.
4y² - 7y - 6 = 4(5²) - 7(5) - 6
= 4 × 25 - 35 - 6
= 100 - 35 - 6
= 59
What is the solution of the system of equations below?
y + 2x = 2
y + 4x = 0
F. (1, -4) G. (-1,-4) H. (-1, 4) I. (1, 4)
G
Solution:
Here,
y+2x=2
y=2-2x
Now,
Putting the value of y
y+4x=0
2-2x+4x=0
2+2x=0
2(1+x)=0
1+x=0
x=-1
Then,
Putting the value of x
y=2x-2
=2×-1-2
=-2-2
=-4
Hence,the solution is (-1,-4)
4 + 2x − x = −3x − 4 what is the value of x?
Answer:
1,000,000
Step-by-step explanation:
Answer:
x = -2
Step-by-step explanation:
Hi,
4 + 2x - x = -3x - 4
4 + x = -3x - 4
x = -3x - 8
4x = -8
x = -2

7. On Saturday, a craft store had 150 visitors, and 80% of the visitors made a purchase. Of the customers who made a purchase, 39 customers bought one item, 57 customers bought two items, and the remaining customers bought three or more items. How many customers bought three or more items at the craft store?
Answer:
24 customers bought 3+ items.
Step-by-step explanation:
80% of 150 = 120
39/120 bought 1 item
57/120 bought 2 items
39 + 57 = 96
120 - 96 = 24
24 customers bought 3+ items.
Hope this helps! :)

Which quantity makes the equation true?
x + 3x + _______ = 7x
Answer:
Step-by-step explanation:
C) 3X
Answer: C. 3x
Step-by-step explanation:
Since x and 3x both have x, you can add them together to get 4x (if there is x by itself, it really means that there is one of it, so it would be 1x.)
Then, you subtract 7x by 4x, which gives you the answer, 3x. You could also solving it by asking yourself: What number plus 4x equals 7x, which would give you 3x.
