(−2x2+3)−(3x2+4x−5)
9514 1404 393
Answer:
-5x² -4x +8
Step-by-step explanation:
Eliminate parentheses and collect terms.
(-2x² +3) -(3x² +4x -5)
= -2x² +3 -3x² -4x +5
= (-2-3)x² -4x +(3 +5)
= -5x² -4x +8
-5x² -4x +8
remove parentheses and collect terms.
(-2x² +3) -(3x² +4x -5)
= -2x² +3 -3x² -4x +5
= (-2-3)x² -4x +(3 +5)
= -5x² -4x +8

Jacob has a list of the estimated costs for each semester to attend a four-year university. What is the total estimated cost to attend college for four years?
Tabel:
Item Cost
Tuition and Fees $3,725.00
Room and Board $2,800.00
Books and Supplies $700.00
Personal Expenses $900.00
A. $8,125
B. $16,250
C. $65,000
D. $32,500
Answer: A, 8125
Step-by-step explanation:
3,725 + 2800 + 700 + 900
3725 + 2800 = 6525
700 + 900 = 1600
6525 + 1600 = 8125
The total estimated cost to attend college for four years is $65,000.00.
Option C is the correct answer.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
Number of semesters in 4 years.
= 2 x 4
= 8
Now,
To find the total cost to attend college for four years, we need to multiply the cost of each item by the number of semesters in four years and add them all together.
So,
Tuition fees:
8 semesters x $3,725.00/semester
= $29,800.00
Room and board:
8 semesters x $2,800.00/semester = $22,400.00
Books and supplies:
8 semesters x $700.00/semester = $5,600.00
Personal expenses:
8 semesters x $900.00/semester = $7,200.00
Therefore,
The total estimated cost to attend college for four years.
= $29,800.00 + $22,400.00 + $5,600.00 + $7,200.00
= $65,000.00
Thus,
The total estimated cost to attend college for four years is $65,000.00.

Answer:
A. x < 2
Step-by-step explanation:
Open and closed circles are used to mark the end points of intervals. If the circle is open, it means the end point is NOT included in the interval, but if the circle is closed, it means the end point is included. Consider the interval . In this interval, the low endpoint, the 3, is not included because you have a 'less than' sign.

Dmitri has a pair of standard dice; one die is blue, and the other die is yellow. He rolls both of his dice. How many ways could the number on the blue die be larger than the number on the yellow die?
=========================================================
Explanation:
I'll use ordered pair notation to indicate the dice results. I'll have blue go first, then yellow second. Something like (6,3) means that blue got 6 while yellow got 3. Another example of (5,2) means the blue die shows 5 while the yellow one shows 2.
Now let's say the blue die rolls to show "1". Is it possible for the blue die to have a larger value than the yellow die? The answer is "no" because it's not possible to roll 0 on the yellow die, and we can't roll negative values either. This means that if we want the blue die to show a value larger than the yellow die, then it must be larger than 1.
If the blue die shows "2", then the only outcome to fit the description is to have the yellow die show "1". We write that as the ordered pair (2,1). Writing (1,2) is the other way around so we'll ignore that. Any other value on the yellow die is not possible since something like (2,5) does not fit the conditions given to us.
If the blue die shows "3", then we could have (3,1) or (3,2) that fit the conditions that the blue die is larger than the yellow one. We have two cases here compared to the one earlier.
If the blue die shows "4", then we could have (4,1) or (4,2) or (4,3). We have three cases here.
You can probably spot the pattern:
We have one case if the blue die shows "2"We have two cases if the blue die shows "3"We have three cases if the blue die shows "4"and so on. The number of cases is one less than whatever the blue die value is showing. Overall we have 1+2+3+4+5 = 15 possible ways to have the blue die be a larger value than the yellow die. Use of a dice chart is handy to help confirm the answer.

Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
since we know the angle and the Hyp, and want to find the opp, use
SOH
Sin(41) = Opp / 111
111*Sin(41) = Opp
72.82255... = Opp

A rectangular roof shingle has a perimeter of 32 inches and an area of 60 square inches. What are the dimensions of the shingle?
Answer:
Length = 6 inches, Width = 10 inches
Step-by-step explanation:
A rectangular roof shingle has a perimeter of 32 inches and an area of 60 square inches. What are the dimensions of the shingle?
Note :
L = Length
W = Width
The perimeter of a rectangle = 2( L + W)
The area of a rectangle = LW.
A rectangular roof shingle has a perimeter of 32 inches and an area of 60 square inches.
32 = 2( L + W)
Divide both sides by 2
16 = L + W.... Equation 1
L = 16 - W
Also:
LW = 60....... Equation 2
Let us substitute 16 - W for L in Equation 2
(16 - W)W = 60
16W - W² = 60
W² - 16W + 60 = 0
W² - 6W - 10W + 60 = 0
W(W - 6) - 10(W - 6) = 0
W - 6 = 0, W = 6 inches
W - 10 = 0, W = 10 inches
Solving for L
W = 10
L = 16 - 10
L = 6 inches
Therefore, the dimensions of the shingle =
Length = 6 inches, Width = 10 inches
