Answer:
the answer is log3 (2x+8)=log3 x²
Step-by-step explanation:
log3(2x^4+8x^3)-3log3x=2log3x
simplifying the above we get:
log3(2x^4+8x^3)=2log3x+3log3x
log3(2x^4+8x^3)=5log2x
Hence the answer should be:
log3 (x³)*(log3(2x+8))=5log3 x
3log3 x+log3(2x+8)=5log3 x
log3(2x+8)=5log3 x-3log3 x
log3 (2x+8)=2log3 x
log3 (2x+8)=log3 x²

While working on homework last night, Kayla completed 4 homework assignments in 3.2 hours. The same night, Karen completed 6 homework assignments in 5 hours. Who spent the least amount of time on homework per hour?
Answer:
Kayla
Step-by-step explanation:
To find who spend the least amount of time on homework per hour, divide the number of hours by the amount of homework
Kayla: 3.2 ÷ 4 = 0.8
Karen: 5 ÷ 6 = 0.833
Since Kayla's number is lower, that means she spent fewer hours per homework than Karen. This means Karen spent the least amount of time in hours per homework.

Estimate the size of a crowd at a political rally that occupies a rectangular space with dimensions of 500 feet by 600 feet (to the nearest whole number). Assume that each person occupies 4. 5 square feet.
The size of a crowd at a political rally which occupies a rectangular space with dimensions of 500 feet by 600 feet is 66667 persons.
What is the area of a rectangle?Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,
[tex]A=a\times b[/tex]
Here, (a)is the length of the rectangle and (b) is the width of the rectangle
The size of a crowd at a political rally that occupies a rectangular space with dimensions of 500 feet by 600 feet has to estimated.
First find out the area of this rectangular space using the above formula.
[tex]A=500\times600\\A=300000\rm\; ft^2[/tex]
As each person occupies 4.5 square feet. Thus, the number of person feet in, 300000 square ft are,
[tex]n=\dfrac{300000}{4.5}\\n\approx66667[/tex]
Thus, the size of a crowd at a political rally which occupies a rectangular space with dimensions of 500 feet by 600 feet is 66667 persons.

70° and 70°
Answer: 30° and 110°
55° and 85°
70° and 70°
The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:
= 180° - 40°
= 140°
Therefore,
30° + 110° = 140°
55° + 85° = 140°
70° + 70° = 140°

Anitra sells cosmetics by mail and weighs each package before sending it.
The table shows the number of each item in a particular package and the total weight.
The system of equations can be used to show the relation between the items in a package and the weight of the package.
The system of equations for this problem is defined as follows:
3x + y = 21.2x + 2y = 24.From the first equation, we have that:
y = 21 - 3x.
The second equation is given as follows:
2x + 2y = 24.
Simplifying the equation, we have that:
x + y = 12.
Replacing the first equation, we have that the value of x is obtained as follows:
x + 21 - 3x = 12
2x = 9
x = 4.5.
Then the value of y is of:
4.5 + y = 12
y = 7.5.

Maria has $32. She earns $12 for 1 hour of cleaning. She wants to buy a birthday gift for her friend for $125. Enter the minimum number of hours Maria must tutor to be able to buy the gift
Answer:
8 hours
Step-by-step explanation:
First, you must subtract $32 from $125. You end up with $93.
Usually, you would do 93 divided by 12, but 93 is not a multiple of 12.
96, which is 12 times 8, is the closest to 93, so 8 hours is the correct answer.
16.5 is 12% of what number?
Answer:
Let's set up an equation;
12/100 * x = 16.5
where 12/100 is 12%
x is the number of the 12%
that would equal 16.5
So solve for x;
12/100 * x = 16.5
12/100x = 16.5
0.12x = 16.5
/0.12 /0.12
x = 137.5

Answer:
B
Step-by-step explanation:
This is a distance versus time graph. The slope on a given interval gives you speed.
So if the slope is going upwards, the speed is increasing which means it isnt constant
If going downwards, the speed decreasing, which means it isn't constant
If forming a horinzontal line, it has slope of 0, which means that it has a constant speed
The only time speed is constant is at 4.

What are polynomial?Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.
In order to factorize the given polynomial, we need to take the common terms out of the polynomial. Therefore, the polynomial can be written as
[tex]5x^4 - 80\\\\[/tex]
If we look at the polynomial the common term 5 can be taken out from both the terms, therefore,
