Answer: Its D
Step-by-step explanation:
Thank me later.
Answer:
D
Step-by-step explanation:
4x - 12 - x ≥ 3
Add 12 to both sides.
4x - x ≥ 15
Subtract x (or 1x) from 4x
4x - x = 3x
3x ≥ 15
Divide both sides by 3.
x ≥ 5

if the foci of an ellipse are the same ordered pair, is the comic a circle?
Answer:
yes
Step-by-step explanation:
I WILL MARK BRAINILIEST !!! Factor the polynomial 20x3 + 34x2 + 6x completely.
2x(2x + 3)(5x + 1)
2x(2x + 1)(5x + 3)
2(2x + 3)(5x + 1)
(4x2 + 6x)(5x + 1)
Solution:
[tex]\text G\text i\text v\text e\text n\ \text e\text x\text p\text r\text e\text s\text s\text i\text o\text n: 20x^{3} + 34x^{2} + 6x[/tex]
Step-1: Find the GCF of the terms.
[tex]20x^{3} \ \ \ = \ \ \ 2 \times 2 \times 5 \times x \times x \times x \\34x^{2} \ \ \ = \ \ \ 2 \times 17 \times x \times x \\ 6x \ \ \ \ \ \ = \ \ \ 2 \times 3 \times x[/tex]
GCF = 2x
Step-2: Factor the expression using the GCF.
[tex]20x^{3} + 34x^{2} + 6x \\\\ {2x(10x^{2} + 17x + 3)}[/tex]
Step-3: Further factorize.
[tex]{2x(10x^{2} + 17x + 3)}[/tex]
[tex]2x(2x + 3)(5x + 1)[/tex]
Thus, the factorized expression is [tex]2x(2x + 3)(5x + 1)[/tex].

The solutions of the given linear equations are: x = 7, - 13; x = 6, - 7; x = 5, - 9, respectively.
What is a linear equation?A linear equation is an equation that has on or multiple variables with the highest power of the variable is 1.
Given equations are:
1. |3x + 9| = 30
⇒ ( |3x + 9| )² = (30)²
⇒ 9x² + 54x + 81 = 900
⇒ 9x² + 54x + 81 - 900 = 0
⇒ 9x² + 54x - 819 = 0
⇒ 9(x² + 6x - 91) = 0
⇒ (x² + 6x - 91) = 0
⇒ (x + 13)(x - 7) = 0
⇒ x = 7, - 13
2. |2x+1| = - 13
⇒ (|2x+1|)² = (- 13)²
⇒ 4x² + 4x + 1 = 169
⇒ 4x² + 4x - 168 = 0
⇒ 4(x² + x - 42)= 0
⇒ (x² + x - 42)= 0
⇒(x - 6)(x + 7) = 0
⇒ x = 6, - 7
3. |x + 2| + 4 = 11
⇒ |x + 2| = 7
⇒ (|x + 2|)² = 7²
⇒ x² + 4x + 4 = 49
⇒ x² + 4x - 45 = 0
⇒ (x - 5)(x + 9) = 0
⇒ x = 5, - 9

Jack Talon rolled 82 barrels onto the ship's
deck. 50% of those barrels were empty. How
many empty barrels did Jack roll onto the
ship's deck?
Answer:
41
Step-by-step explanation:
You do 50% of 82 which is 41.
Answer: 41 empty barrels
Step-by-step explanation:
if Jack rolled 82 total barrels and 50% of them were empty, that is the same as taking 82 times .5, which gives us 41. This is how we know he rolled 41 empty barrels onto the ships deck.
A path 5m wide runs along inside a rectangular field. The length of the rectangular field is three times the breadth of the field. if the area of the path is 500m2, then find the length and breadth of the field..
Answer:
Length = 45m
Breadth = 15m
Step-by-step explanation:
Dimensions of Rectangular field:
Let the breadth (B)=BC = x m
Length (L) = AB = 3x m
width of the road (w) = 5 m
Dimensions of inner rectangle:
length (l) = EF = L-2w
= 3x - 2×5
= (3x-10) m
breadth (b)=EH = B-2w
= (x-10) m
Given ,
Area of the path =500 m²
=> Area of ABCD - Area of EFGH = 500
=> L×B - l×b=500
=> (3x)× x - (3x-10)(x-10)=500
=> 3x²-(3x²-30x-10x+100)=500
=> 3x²-3x²+30x+10x-100=500
=> 40x=500+100
=> 40x = 600
=> x = 600/40
=> x = 15
Therefore,
Length (L) = 3x = 3×15 = 45m
Breadth (B) = x = 15m

Which identity or property is used during the first step when solving the equation 23−8x=16(4x−1)?
Additive Identity
Associative Property
Distributive Property
Multiplicative Identity
Answer:
Multiplicative Identity
Step-by-step explanation:
This is what they all basically mean:
Additive Identity - addition
Associative Property - simplifying
Distributive Property - multiplying brackets, or expanding
Multiplicative Identity - multiplication
In this equation, you first expand 16(4x-1) which uses multiplication but only has one bracket meaning, you use multiplicative identity first.

1/5 divided by -1/14?
Answer:
-2.8 or -14/5
Step-by-step explanation:
To divide one fraction by another, there is a really cool method called Keep Change Flip
Keep the first fraction
Change the division sign to multiplication
Flip the numbers on the last fraction
Let's try it out.
Keep the 1/5
Change the ÷ to a ×
Flip the -1/14 to a -14/1
1/5 × -14/1
Multiply the top numbers by each other first
1 × -14 = -14
Now the bottom numbers
5 × -1 = -5
The fraction we have now is -14/5
It can also be written as -2.8

If the circle has a diameter of 2 inches, then it has a circumference of 6.28 inches.
Answer:
True, the diameter=2in and the circumference=6.28
Step-by-step explanation:
The circumference, C, of a circle is found by the following equation: C = 2 x pi x r where r equals the radius of the circle (or half its diameter) and pi = 3.14159 (a constant).
Thus, 6.28 = 2 x pi x r
Solving for r: 6.28/(2 x pi) = r
or: 6.28/(2 x 3.14) = 6.28/6.28 = r
thus r = 1 and since the diameter equals 2 x r, the diameter is 2.
