Will give brainliest! If you are unsure do not answer.
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.
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.

Rita and her two children live in subsidized housing and pay monthly rent of $230. The cost of heating
is included in the rent. The electric bill averages $56 a month while the water and sewage bill averages
$35 for every 3 months of use. Telephone costs average $19.50 a month. Rita carries no renters
insurance on her personal property. What is Rita's total annual cost of renting?
Answer:
$3806
Step-by-step explanation:
230.0
56.0
+ 19.50
305.50
305.5x12=3666
35x4=140
3666+140=3806

Answer:
The measure of the angle [tex]b[/tex] is approximately 44.040°.
Step-by-step explanation:
We need to apply Law of the Sine to determine the value of angle [tex]b[/tex], since the length of the side opposite to this side and another side length and its opposite angle are known. That is:
[tex]\frac{3.6}{\sin b} = \frac{5.1}{\sin 100^{\circ}}[/tex]
[tex]\sin b = \frac{3.6}{5.1}\times \sin 100^{\circ}[/tex]
[tex]b = \sin^{-1}\left(\frac{3.6}{5.1}\times \sin 100^{\circ} \right)[/tex]
[tex]b \approx 44.040^{\circ}[/tex]
The measure of the angle [tex]b[/tex] is approximately 44.040°.

A copper plate is in the shape of an isosceles triangle with a base of 34 inches. The perimeter of the plate is 110 inches. How long is each of the equal sides of the plate
Answer:
An isosceles triangle has 2 equal sides. If the perimeter is 110 inches, and your base is 34 inches, subtract the base from the total perimeter. 110-34= 76. If 2 sides have to be equal, the total length of the 2 sides is 76 inches, divide the 2 lengths by 2 to get the measure of each side individually. 76÷2=38.
Hence, your answer is each of the equal sides of the plate equals 38 inches.

Step-by-step explanation:
Twenty more than four times a number is equal to the difference between −71 and three times the number. Find the number.
4x + 20 = - 71 - ( 3x )
4x + 20 = - 3x - 71
Subtract sides minus 20
4x + 20 - 20 = - 3x - 71 - 20
4x = - 3x - 91
Add sides 3x
4x + 3x = - 3x + 3x - 91
7x = - 91
Divide sides by 7
7x / 7 = - 91 / 7
Simplification
x = - 13
Thus the number is ( - 13 ) .

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
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

Step-by-step explanation:
We will be using pythagoras theorem.
Therefore, we will have: [tex]a^{2}[/tex] + [tex]x^{2}[/tex] = [tex]13^{2}[/tex]
Moreover, we have: [tex]a^{2}[/tex] = [tex]4^{2} + 3^{2}[/tex] => [tex]a^{2}[/tex] = 25
=> 25 + [tex]x^{2}[/tex] = 169
=> [tex]x^{2}[/tex] = 144 => x = [tex]\sqrt{144}[/tex] = 12

If 2x⁴ + 2y⁴ + 2z⁴ = 144, what is the mean of x⁴, y⁴ and z⁴
Answer: 24
Step-by-step explanation:
Given
[tex]2x^4+2y^4+2z^4=144[/tex]
dividing whole equation by 2, we get
[tex]\Rightarrow x^4+y^4+z^4=72[/tex]
Mean is given by the sum of the value of entities divided by the total no of entities
[tex]\Rightarrow \text{Mean}=\dfrac{x^4+y^4+z^4}{3}\\\\\Rightarrow \text{Mean}=\dfrac{72}{3}\\\\\Rightarrow \text{Mean}=24[/tex]

There was a triangle ABC with sides 15, 20, and 10. One of the sides of a triangle, which is similiar to ABC is 60. What are the two other sides? Note: Give all possible answers
Answer:
The possible pairs of sides are 90 and 120, 30 and 45, and 80 and 40.
Step-by-step explanation:
We know that 60 is a multiple of 15, 20, and 30, so we multiply by each factor to find all possible pairs: 10x6=60, 20x6=120, and 15x6=90, that gives your first pair, 90 and 120.
We have now multiplied our first factor, 6. Now we need to multiply our second factor, 3: 20x3=60, 15x3=45, and 10x3=30. That gives your second pair, 30 and 45.
Finally, we need to multiply by our 3rd factor, 4: 15x4=60, 20x4=80, and 10x4=40. That gives you your final possible pair, 80 and 40.
