Answer:
D. (x-3)(x-3)(x-1)
Step-by-step explanation:
(x³-7x²+15x-9)/(x-3) = x²-4x+3 (see attached)
x²-4x+3=(x-1)(x-3) (factorisation)
∴x³-7x²+15x-9=(x-3)(x-3)(x-1)

The sum of a two digit number and the number obtained by interchanging the digits is 132. If the two digits differ by 2, find the number
Answer:
A two-digit number can be written as:
a*10 + b*1
Where a and b are single-digit numbers, and a ≠ 0.
We know that:
"The sum of a two-digit number and the number obtained by interchanging the digits is 132."
then:
a*10 + b*1 + (b*10 + a*1) = 132
And we also know that the digits differ by 2.
then:
a = b + 2
or
a = b - 2
So let's solve this:
We start with the equation:
a*10 + b*1 + (b*10 + a*1) = 132
(a*10 + a) + (b*10 + b) = 132
a*11 + b*11 = 132
(a + b)*11 = 132
(a + b) = 132/11 = 12
Then:
a + b = 12
And remember that:
a = b + 2
or
a = b - 2
Then if we select the first one, we get:
a + b = 12
(b + 2) + b = 12
2*b + 2 = 12
2*b = 12 -2 = 10
b = 10/2 = 5
b = 5
then a = b + 2= 5 + 2 = 7
The number is 75.
And if we selected:
a = b - 2, we would get the number 57.
Both are valid solutions because we are changing the order of the digits, so is the same:
75 + 57
than
57 + 75.

Jenny is saving for a vacation to the beach. How much interest will she earn if
she invests $600 at 4.25% simple interest for 10 years?
Matthew invested $5,300 in an account paying an interest rate of 2.1% compounded annually. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $6,020?
Answer: it would be 6
Step-by-step explanation
Delta math
Based on the information for the value of the account to reach $6,020? given it will take 6 years.
Value of account:Let x represent the number of years
(2.1%×5,300)x+5,300=6,020
111.3x+5,300=6,020
Collect like terms
111.3x=6,020-5,300
111.3x=720
Divide both side by 111.3x
x=720/111.3
x=6 years
Inconclusion for the value of the account to reach $6,020? given it will take 6 years

14 less than the quantity k times 6
(Write it as an algebraic expression)
Answer:
6k-14
Step-by-step explanation:
The algebraic expression for inequality is 14 < 6k.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
We have the statement
14 less than the quantity k times 6
Now, k times 6 = 6k
and, 14 less than k times 6 can written into mathematical form as
14 < 6k
k > 14/6
k> 7/3.

Kara has 4/5 gallon milk, she gives some to her brother. Now she 1/3 gallon of milk. How much milk, in gallons, did she give to her brother
Answer:
7/15 of a gallon
Step-by-step explanation:
Her starting amount 4/5 is equivalent to 12/15. Her ending amount 1/3 is equal to 5/15. So subtract her end amount from her starting amount to find how much she gave to her brother. 12/15 - 5/15 = 7/15.

349 + 4.80n
3
135
Step-by-step explanation:
1
For this, use the equation I gave you above to find the costs.
2
First, the cost of the printer will NOT change, for the number of printers Eddie needs to buy does not change, he only needs one. This already helps you figure out that 349 is not a coefficient to the variable, n. However, when it comes to the number of blank shirts Eddie needs to buy, the number of he gets does change, this is the dependent variable that makes the cost vary. Using the equation above, you can plug in any number.
For example, 20.
349 + 4.80(20) = 445
3
For this final part, I just kept using the equation until I got the closest number that is lower than 1000. In this case, 135 got me 997, and 136 was just a few decimals away from 1000, but it was still over.

11. Stan Still is trying to record the dimensions of a "flag plot" (a triangular piece of land) where a house will be built. He has found that two consecutive sides of the plot have lengths of 70 yards and 95 yards. He has also determined that the angle between the two side is 82 degrees. To the nearest yard, what is the length of the final side of the plot?
Answer: 110 yards.
Step-by-step explanation:
According to the cosine formula,
In a triangle, if a and b are two consecutive sides and x is the angle between them, then the measure of the third side (c) is given by:-
[tex]c=\sqrt{a^2+b^2-2ab\cos x}[/tex]
As per given, a= 70 yards , b= 95 yards , x= 82 degrees
The final side = [tex]\sqrt{(70)^2+(95)^2-2(70)(95)\cos 82^{\circ}}[/tex]
[tex]=\sqrt{4900+9025-13300(0.139173)}\\\\=\sqrt{13925-1851} \\\\=\sqrt{12074}\\\\\approx110\text{ yards}[/tex]
I.e. the length of the final side of the plot is 110 yards.

On the first night of Rosh Hashanah, David cuts 5 apple into slices and gives 3/8 of an apple to each of his quests. He has 2 apples left over. How many guests does David have?
Answer:
Number of guests = 8
Step-by-step explanation:
Total apples David cut = 5
Total apples left over = 2
Total apples David gave his guest = Total apples David cut - Total apples left over
= 5 - 2
= 3
Total apples David gave his guest = 3
Each guest gets = 3/8 of an apple
Number of guests = Total apples David gave his guest ÷ share of each guest
Number of guests = 3 ÷ 3/8
= 3 × 8/3
= 8
Number of guests = 8

Suzy is competing in a 651 mile long-distance bicycle race. In the first 3 and 1/2 hours she completed 54 and 1/4 miles. If she plans to ride 7 hours per day, how many days will it take for her to complete the race at that pace?
Answer: 6 days
Step-by-step explanation:
1. Multiply 54 1/4 by 2 (We are multiplying my 2 because 3 1/2 hours is half of 7 hours, so you have to multiply to see how much Suzy rode for 7 hours.
2. Now, divide 651 by the answer you get in step 1 to get your answer (simplify if necessary.)
=> 54 1/4 * 2 = 108 1/2
=> 651 / 108 1/2 = 6
