The three is negative
All exponents are not whole numbers
There are only three terms
The highest exponent is 2
Answer:
The three is negative
Step-by-step explanation:
A polynomial cannot have a variable in the denominator or a negative exponent so the reasoning is Because the three is negative

28inch^2
Step-by-step solution:Rectangle:
[Length x Breadth]
5 + 3 = 8inch
8 x 2.5 = 20inch^2
Right Triangle:
[1/2 x Base x Height]
1/2 x 5 x 2 = 1/2 x 10
= 5inch^2
Left Triangle:
[1/2 x Base x Height]
1/2 x 3 x 2 = 1/2 x 6
= 3inch^2
20 + 5 + 3 = 28inch^2
How much of a radioactive kind of antimony will be left after 120 days if you start with 904 grams and the half-life is 60 days?
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
y = final amount after x daysa = initial amountx = number of days that elapseH = number of days in a half-lifeIn this case,
a = 904 is the starting amountH = 60 is the number of days until another half-life occursWhen x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.

Solve for h.
h/10 + 5 = 25
so what’s h ??
Answer:
h=200
Step-by-step explanation:
h/10+5=25
h/10=20
h=200
h/10 + 5 = 25
Subtract 5 from each side to get h/10 alone.
h/10 + 5 - 5 = 25 - 5
h/10 = 20
Multiply both sides by 10 to get h alone.
h/10 • 10 = 20 • 10
h = 200
h = 200. I hope this helps!

Answer:
y +2 = (1/4)(x +1)
Step-by-step explanation:
The given line is in slope-intercept form:
y = mx + b
where the slope (m) is -4 and the y-intercept (b) is +13.
For the perpendicular line, we need a slope that is the opposite reciprocal, or ...
-1/m = -1/(-4) = 1/4
A suitable form for the desired equation is the point-slope form:
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
For m=1/4 and (h, k) = (-1, -2), the equation of the line is ...
y +2 = (1/4)(x +1)
what is the period of the sinusoidal function
Answer:
10Step-by-step explanation:
Period is the distance between two consecutive maximum points, or two consecutive minimum points.On the given graph the period is the distance between maximum points -7 and 3:
3 - (-7) = 10Answer:
The period of the sinusoidal function is 2π, i.e., the value of the function repeats at every 2π units.
From the origin towards right we can see that the distance traveled between 0 to 2π is 10 units
Therefore, 10 units is the right answer.

Find the distance between the two points in simplest radical form. (4,4) and (8,-3)
Answer:
2/5
Step-by-step explanation:
If you have two point of the form(x_1,y_1) and (x_2,y_2) then the distance between these points is d=√(x_1-x_2)^2+(y_1-y_2)^2
In this case:
d=/(-8-(-6))^2+(-2-2)^2
d=/(-8+6)^2+(-4)^2
d=/(-2)^2+16
d=/4+16
d=/20
d=2/5

4(x-2)/5 = 20
(Yes that’s a fraction)
Solving for x
Answer:
x=27
Step-by-step explanation:
Step 1: Multiply both sides by 5.
4(x−2)
5=20
(4(x−2)*(5)*(5)=(20)*(5)
4(x−2)=100
Step 2: Simplify both sides of the equation.
4x−8=100
Step 3: Add 8 to both sides.
4x−8+8=100+8
4x=108
Step 4: Divide both sides by 4.
4x/4=108/4
x=27
Step-by-step explanation:
(x-2)/5 = 5
(x-2) = 25
x = 27

imagine you're in a queue to the airport check-in desk if two-thirds of the queue is in front of you and three tenths of the queue is behind you how many people are in the queue
Step-by-step explanation:
Let x be the number of people in the queue, including yourself.
We have 2/3 x + 1 + 3/10 x = x.
=> 29/30 x + 1 = x
=> x/30 = 1
=> x = 30.
Hence there are 30 people in the queue.

The side length of an equilateral triangle is 6x - 12. Write an expression for the perimeter of the triangle in simplest form.
Answer:
18x - 36
Step-by-step explanation:
In an equilateral triangle the 3 sides are congruent, then
perimeter = 6x - 12 + 6x - 12 + 6x - 12 ← collect like terms
= 18x - 36
The required expression would be 18x - 36 for the perimeter of the triangle in simplest form.
What is the perimeter of a triangle?The perimeter of a triangle is defined as the addition of the lengths of the triangle's three sides.
What are Arithmetic operations?Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
As we know in an equilateral triangle the 3 sides are congruent.
The perimeter of the triangle = 6x - 12 + 6x - 12 + 6x - 12
Combine the likewise terms and we get
The perimeter of the triangle = 18x - 36
Therefore, the required expression would be 18x - 36 for the perimeter of the triangle in simplest form.

Michael is buying a pair of jeans that regularly cost $40. They are on sale for 20% off. If the tax rate is 6%, what is the sale price of the Jeans
including tax?
Answer:
The jeans will cost 33.92
Step-by-step explanation:
20% of 40 is 8, and 40 - 8 is 32.
6% of 32 is 1.92 and 32 + 1.92 is 33.92
Trey deposits $700 into an account that pays simple interest at a rate of 6% per year. How much interest will he be paid in the first 3 years?
Answer:
$1.26
Step-by-step explanation:
$700 times 0.06 times 3 = 126
126 divided 100 = 1.26
the formula of simple interest is
Amount times Rate times Time divided by 100
Trey deposits $700 into an account that pays simple interest at a rate of 6% per year. $1.26 interest he will be paid in the first 3 years.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time peroid.
Simple Interest = (Principal × Rate × Time) / 100
Trey deposits $700 into an account that pays simple interest at a rate of 6% per year.
Simple Interest = (Principal × Rate × Time) / 100
= $700 x 0.06 x 3
= 126 / 100
= 1.26
