Q: compare and examine the difference between each of the following pairs of expressions.
•2n and 2 + n
•n² and 2n
•2n² and (2n)²
Comment whether each pair of expressions is equal. Explain ur answer.
Answers
Answer:
None of the pairs of expressions are equal
Step-by-step explanation:
• 2n ≠ 2 +n
2n is the same as 2 times of n (expressed as a multiplication sign), while 2 +n is the addition of 2 to n.
•n² ≠ 2n
n²= n ×n
2n= 2 ×n
• 2n² ≠ (2n)²
Note that in the latter, there is a bracket which means that the square applies to both 2 and n.
(2n)²
= (2)² × n²
= (2 ×2)(n²)
= 4n²
Thus, none of the pairs of expressions are equal.

what is the width of a rectangle with length 25in and area of 375^{2}
Answers
Explanation:
I'm assuming you meant to say the area is 375 in^2, aka 375 square inches.
If so, then,
area of rectangle = length*width
A = L*W
A/L = W
W = A/L
W = 375/25
W = 15 inches
As a check,
A = L*W = 25*15 = 375 which helps confirm the answer.

This week Harry spent 1/2
of his pocket money on a ticket for a football ma
He also spent 1/8
of his pocket money on a scarf at the match.
(a) What fraction of his pocket money has Harry spent?
(b) What fraction of his pocket money does Harry have left?
Answers
b) harry has 3/8 of his pocket money left
HOW I DID IT
basically we want to add fractions in the first part so ( 1/2 + 1/8 ) to do this you have to make the denominator equal (number on the bottom) so to get 2 to 8 you have to multiply it by 4 and whatever you do to the bottom you have to do to the top so you multiply the top by 4 as well that gives you 4/8 + 1/8 and you just add the top numbers then you find out the difference for the second part of the equation
The fraction of money spent is 5 / 8 x.
The fraction of money left is 3 / 8 x.
How to find the fraction of money he spent?This week Harry spent 1/2 of his pocket money on a ticket for a football match. Therefore,
let
x = amount of money he has
Therefore,
amount spent on football match = 1 /2 x
He also spent 1/8 of his pocket money on a scarf at the match.
Therefore,
amount spent on scarf = 1 / 8 x
Fraction of money spent = 1 / 2 x + 1 / 8 x = 4 + 1 / 8 = 5 / 8 x
Fraction of money left = x - 5/8 x = 8x - 5x/8 = 3 / 8 x

Micheala pays her cell phone service provider $19.95 per month for her service plan and 15 cents per minute. In June, her phone bill is $127.95. How many minutes did micheala use in June
Answers
Answer:
720 minutes
Step-by-step explanation:
Total phone bill = $127.95
Service plan fee = $19.95
Total cost per minute = 127.95 - 19.95
= $108.00
No. of minutes used = Total cost per minute / Rate per minute
= 108.00 / 0.15
= 720 minutes

Answers
Answer:
No, they are co-planar.
Step-by-step explanation:
Points Q, R, X, and W are all in the plane QRXW. Planes do not have to be at ninety-degree angles (that is, straight up and down or straight to the left and right). However, the points Q, S, U, and X would not be coplanar as a plane must be a flat surface.
Which inequality is represented by the graph
Answers
Answer:
y ≥ -2x + 2.5
Step-by-step explanation:
It's kind of hard to tell because no points are given on the graph, but we can first find the b value of 2.5 in the equation y = mx +b as it is the y-intercept.
Using that value, we can also recognize that at one, it looks like the y-value is .5. using our slope formula (change in y / change in x), we can plug in the two points of (0, 2.5) and (1, 0.5) to get a slope of -2.
Now that we have our equation, we can make it an inequality!
Since the graph is shaded upwards, we know it is going to be a greater than symbol, and since the line itself solid and not dotted, we know that the points on the line are also solutions, meaning that it is also equal to the line
Hence, we get the ≥ sign.
Putting it all together, we get our final equation of y ≥ -2x + 2.5 ! :))

Is he square root of -144 rational or irrational?
Answers
Answer:
Step-by-step explanation:
Neither.
It is a complex number. The - sign is the culprit. sqrt(-144) = i * sqrt(144) = 12 i
The "i" is an imaginary representation for the square root of -1. It is a definition for sqrt(-1). So a new category of number has been created. The ancients would have been profoundly surprised to learn that such a thing existed.

Step-by-step explanation:
Let the ends of the line segment be A(-1,9) and B(3,-7)
Divided in the ratio m:n by a point P
By formula of coordinate geometry,
[tex]$X=\frac{5 * 3+3 *(-1)}{5+3}$[/tex]
