The perimeter of a rectangle is represented by 4x^2+5x-2. The perimeter of a smaller rectangle is represented by x^2+3x+5. Which polynomial expression represents how much larger the first rectangle is than the smaller rectangle ?
PLease help !!!!
Answers
a is correct
Step-by-step explanation:
Area of Bigger rectangle = 4x2 + 5x - 2
Area of Smaller rectangle = x2 + 3× + 5
diff. = ( 4x2 + 5x - 2) - (x2 + 3x - 5)
= 4x2 + 5x -2-x2 - 3x - 5
= 3x2 + 2x - 7

If I have an 86% overall grade in a class and score 40% on a test, what will my grade come out as?
Answers
Answer:
It really depends on how much percent of your overall grade tests count as. But, usually they count for about 60% of your grade (depending on what grade you are in). You have about 65% at the lowest and a 75% at the highest. But, I'm just going by what my school does, I don't know how your school grades tests.

2) Christmas is on its way, so the price of a box of Thornton's chocolates has been increased
by 15%!! A box of Thornton's Continental now costs £17.25. How much did it cost
originally?
Answers
Our regular cost of chocolates is 1.0
New cost is 1.0 + 0.15 = 1.15
1.15 x 17.25 = 19.8375
In the states we round to the hundredth for cost, so it would be £19.84
Alternate method: calculate 0.15 of 17.25 and add that to 17.25
0.15 x 17.25 = 2.5875
17.25 + 2.5875 = 19.8375

Answer:
90,45,45
Step-by-step explanation:
it a system of equations
say that x y and z are each angles of the triangle
that means that they add up to 180 so x+y+z=180
the question says that two of the angles in the triangle are equal so we can just say that x=y
and it says that the two angles that are the same length have a sum that is equal to the third side of the triangle which basically is x+y=z
x+y+z=180
x+y=z
x=y
we start with the first two equations:
since x+y=z then we can substitute z in for x+y in the first equation
z+z=180
2z=180
z=90
and since x=y then
x+x=z
2x=90
x=45
y=45
z=90
hope that helps :)

What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
The ratio of strawberries to melons is 3:4.
Let us consider,
Strawberries = 3x
Melons = 4x
Now,
A total of 14 cups of fruit were made.
This means,
14 = 3x + 4x
14 = 7x
x = 2
Now,
The number of cups of strawberries is 3x.
3x = 3 x 2 = 6 cups
The number of cups of melons is 4x.
4x = 4 x 2 = 8 cups.
We see that,
6 cups + 8 cups = 14 cups.
Thus,
The number of cups of strawberries Valerie used is 6 cups.

Triangle X has m2A = 30°, mZB = 90°, and m2C = 60° with side lengths of AB = 3, BC = 4, AC = 5.

O They are congruent triangles.
O They are congruent but not similar triangles.
Answers
Answer:
O They are similar triangles.
Step-by-step explanation:
Given
Triangle X
[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°, [tex]\angle C = 60[/tex]°
[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]
Triangle Y
[tex]\angle A = 30[/tex]°, [tex]\angle B = 90[/tex]°, [tex]\angle C = 60[/tex]°
[tex]AB = 9,\ BC = 12,\ AC = 15.[/tex]
Required
The relationship between X and Y
From the given parameters, the corresponding angles of both triangles are equal i.e.
A = A, B = B and C = C
However, the side lengths are not equal.
The side lengths of Y is 3 multiplied by the side lengths of X.
This is shown below:
Triangle X
[tex]AB = 3,\ BC = 4,\ AC = 5.[/tex]
Multiply by 2 to get Triangle Y
[tex]AB= 3 * 3 = 9[/tex]
[tex]BC= 4 * 3 = 12[/tex]
[tex]AC = 5 * 3 = 15[/tex]
Since side lengths are not equal, but they have a common ratio of 3, then the triangles are similar.
find the unit rate and show work
289 miles on 10 gallons
Answers
Answer:
28.9 miles per gallon
Step-by-step explanation:
unit rate is usually something per something. Like miles per hour. In this case we have mile per gallon. MPG.
Unit rate is basically A number X per 1 of something.
so in this cares X per gallon.
we want 10 gallons to go to 1 gallon. So we divide by 10 to get to 1. But if we divide by 10 on one side, we have to do it to the other side. so 289/10=28.9
so our final answer is:
28.9 miles per gallon

What is Expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. It's possible to multiply, divide, add, or subtract with this mathematical operation. An expression's structure is as follows:
Expression: (Math Operator, Number/Variable, Math Operator)
We have,
(n² - 7n + 12) / (n-3)(n+4)
So, Factorizing (n² - 7n + 12)
= (n² -3n - 4n +12)
= n(n-3)- 4(n-3)
= (n-3)(n-4)

A hard-boiled egg is removed from a pot of hot water and set on the table to cool. The rate of change of the egg’s temperature T with respect to time t is proportional to the difference between the egg’s temperature in degrees Fahrenheit ( °F) and the room temperature of 75°F. Which of the following is a differential equation that describes this relationship, where k is a constant?
Answers
Answer:
dT/dt = k(T-75)
Step-by-step explanation:
dT/dt = the rate of change of the egg's temperature T with respect to time t
k = constant
(T-75) = difference between the egg's temperature and the room temperature 75 degree
The relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).
From the Newton's law of cooling, the rate of cooling of any object depends on the temperature difference between the object and the surroundings. This is usually expressed in a differential equation.
In this particular instant, the differential equation that shows the relationship between the temperature of the egg and that of the room is dT/dt = k(T-75).

The paperweight is shaped like a square pyramid. The volume of the pyramid is 48 in. If the area of the base is 36 in?, what is the height of the pyramid?
Answers
Given:
Volume of a square base pyramid = 48 cubic inches.
Area of base = 36 sq. inches.
To find:
The height of the pyramid.
Solution:
Volume of a pyramid is
[tex]V=\dfrac{1}{3}Bh[/tex]
Where, B is the base area and h is the height of the pyramid.
Putting V=48 and B=36, we get
[tex]48=\dfrac{1}{3}(36)h[/tex]
[tex]48=12h[/tex]
[tex]\dfrac{48}{12}=h[/tex]
[tex]4=h[/tex]
Therefore, the height of the pyramid is 4 inches.
