Make sure you answer both parts and be detailed in your explanation.
a) The equation 2x + 8 = 2(x+4) works for all values of x. Explain how you know.
b) The equation 3x +7 = 3(x+7) works for no values of x. Explain how you know.
Answers
Answer:
a) because of the distributive property when you distribute you get 2x+8=2x+8
b) because when you distribute, you get 3x+7=3x+21 which is not equal so no value of x will work
Answer:
a) 2x + 8 = 2(x + 4) has infinite solutions because it simplifies down to x = x. Here is the work where this equation is solved.
2x + 8 = 2(x + 4)
2x + 8 = 2(x) + 2(4)
2x + 8 = 2x +8
2x + 8 - 8 = 2x + 8 -8
2x = 2x
2x/2 = 2x/2
x = x
So, because the equation ends in x = x, you can substitute any value for x and the equation will remain true.
----------------------------------------------------------------------------------------------------------------
b) 3x + 7 = 3(x + 7) has no solutions because it simplifies down to an untrue statement. The equation is simplified below.
3x + 7 = 3(x + 7)
3x + 7 = 3(x) + 3(7)
3x + 7 = 3x + 21
3x + 7 - 7 = 3x + 21 - 7
3x = 3x + 14
3x/3 = 3x/3 +14
x = x + 14
However, this is false. x cannot be equal to itself plus 14.
x ≠ x + 14
The simplification of this equation is untrue, so there is no solution to it.

For the polynomial x^3-7x^2+12x-6, 1 is a zero. Express g(x) as a product of linear factors.
Answers
Answer:
(x–1)(x²–6x+6)
Explanation:
Given that 1 is a zero, we can use synthetic division to compute the factor.
If 1 is a zero (x–1) is a factor.
Here is the process:
| 1 | 1 -7 12 -6
↓ +(1) +(-6) +(6)
↓ ↓ ↓
1 -6 6 0
→ [1]x² + [-6]x + [6]1 + [0]/x–1 =
x² – 6x + 6.
Therefore the factors are (x–1)(x²–6x+6)

What is the surface area of the right cone below?
Radius 8
Slanted height 14
A. 896 units2
B. 1677 units2
C. 1767 units2
D. 2247 units
Answers
Total surface area of cone is 176π
Explanation:
Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.
Hence surface area of curved surface of a cone is π×8×14=112π .
As surface area of base is π×82=64π .
Hence total surface area is 112π+64π=176π
The surface area of the given cone is 552.64 units²
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given that, a cone has a radius of 8 and slant height of 14 units, we need to find its surface area,
The surface area of cone = π ·r²+ π·r·l, where l is the slant height,
So,
SA = (3.14 × 8²) + (3.14 × 8 × 14)
= 200.96 + 351.68
= 552.64
Hence, the surface area of the given cone is 552.64 units²

Answers
Answer:
Step-by-step explanation:
Quadratic equation has been given as,
[tex]y=-x^{2} +6x+4[/tex]
Converting this equation into vertex form,
[tex]y=-(x^{2}-6x)+4[/tex]
[tex]y=-[x^{2}-2(3x)+9-9]+4[/tex]
[tex]y=-[x^{2}-2(3x)+3^2]+4+3^2[/tex]
[tex]y=-(x-3)^2+4+9[/tex]
[tex]y=-(x-3)^2+13[/tex]
By comparing this equation with the vertex form of a quadratic equation,
y = (x - h)² + k
Here, (h, k) is the vertex of the parabola.
Vertex of the parabola → x = 3, y = 13
Axis of symmetry → x = 3
