The length of a rectangle is 8 cm greater than its width. Find the dimensions of the rectangle if its area is 105 square centimeters. (a) Write a polynomial equation that can be solved. (b) Solve the equation by factoring (input equation with binomials in this step). (c) State solution with units *
Answer:
105 = (w+8) *w
w = 7 cm
l = 15 cm
Step-by-step explanation:
Area of a rectangle is
A = l*w
l = w+8
105 = (w+8) *w
Distribute
105 = w^2 +8w
Subtract 105 from each side
105-105 = w^2 +8w -105
0 =w^2 +8w -105
Factor
What 2 number multiply to 105 and add to 8
15*-7 = -105
15-7 = 8
(w+15) (w-7) =0
Using the zero product property
w+15 =0 w-7 =0
w=-15 w=7
impossible
not negative
w =7
l = 15
Answer:
Width: w
Length: w + 8
w(w + 8) = 105
w² + 8w - 105 = 0
w² + 15w - 7w - 105 = 0
w(w + 15) - 7(w + 15) = 0
(w + 15)(w - 7) = 0
w = -15, 7
width = 7cm
length = 7+8 = 15cm

Answer:
The product of [tex]3x-9[/tex] and [tex]6x^2-2x+5[/tex] is [tex]18x^3 -60x^2 + 33x - 45[/tex]No, they are not equalStep-by-step explanation:
a. Given
[tex]3x-9[/tex] and [tex]6x^2-2x+5[/tex]
Required
Product
The solution is as follows
First, put both expression in different brackets
[tex](3x-9)(6x^2-2x+5)[/tex]
Expand [tex](6x^2-2x+5)[/tex] bracket by [tex](3x-9)[/tex]
To do that. we first multiply [tex](6x^2-2x+5)[/tex] by 3x then by -9. This is done as follows
[tex]3x (6x^2-2x+5) - 9(6x^2-2x+5)[/tex]
Now, we proceed to opening the bracket
[tex](3x * 6x^2-3x * 2x+3x *5) - (9* 6x^2-9* 2x+9* 5)[/tex]
[tex](18x^3 -6x^2+ 15x) - (54x^2 - 18x +45)[/tex]
Open both brackets
[tex]18x^3 -6x^2+ 15x -54x^2 + 18x -45[/tex]
Collect like terms
[tex]18x^3 -6x^2 -54x^2 + 15x + 18x -45[/tex]
[tex]18x^3 -60x^2 + 33x - 45[/tex]
Hence, the product of [tex]3x-9[/tex] and [tex]6x^2-2x+5[/tex] is [tex]18x^3 -60x^2 + 33x - 45[/tex]
b. Given
[tex]3x-9[/tex] and [tex]6x^2-2x+5[/tex][tex]9x-3[/tex] and [tex]6x^2-2x+5[/tex]Required
Are their products equal?
To check if they are equal or not, we find the product of both and compare the solutions
We've already solved for [tex]3x-9[/tex] and [tex]6x^2-2x+5[/tex] in the (a) part of this exercise, so we move to the product of [tex]9x-3[/tex] and [tex]6x^2-2x+5[/tex]
The solution is as follows
First, put both expression in different brackets
[tex](9x-3)(6x^2-2x+5)[/tex]
Expand [tex](6x^2-2x+5)[/tex] bracket by [tex](9x-3)[/tex]
To do that. we first multiply [tex](6x^2-2x+5)[/tex] by 9x then by -3. This is done as follows
[tex]9x (6x^2-2x+5) - 3(6x^2-2x+5)[/tex]
Now, we proceed to opening the bracket
[tex](9x * 6x^2 - 9x * 2x + 9x *5) - (3* 6x^2 - 3 * 2x + 3* 5)[/tex]
[tex](54x^3 - 18x^2+ 45x) - (18x^2 - 6x +15)[/tex]
Open both brackets
[tex]54x^3 - 18x^2+ 45x -18x^2 + 6x -15[/tex]
Collect like terms
[tex]54x^3 - 18x^2 -18x^2 + 45x + 6x -15[/tex]
[tex]54x^3 - 36x^2 + 51x -15[/tex]
Now, we compare both answers
Is
[tex]18x^3 -60x^2 + 33x - 45[/tex]
equal to
[tex]54x^3 - 36x^2 + 51x -15[/tex]
No, they're not.
Reason is that, for both expressions to be equal, we must have the same expression after expanding both of them

Step-by-step explanation:
A restaurant offers 10 appetizers and 12 main courses. In how many ways can a person order a two-course meal? Use the Fundamental Counting Principle with two groups of items.
Answer:
80 ways
Step-by-step explanation:
The first thing is to apply the Fundamental Counting Principle with two groups of items, in this case the multiplication rule is used.
In this case, what we should do is that, for every 1 main course there are 8 appetizers, but there are 10 main courses therefore:
8 * 10 = 80
There are 80 ways to combine appetizers and the main course
Final answer:
A person can order from a restaurant 120 different two-course meals using the Fundamental Counting Principle, as there are 10 appetizers and 12 main courses to choose from.
Explanation:
The question is asking how many different two-course meals can be ordered if a restaurant offers 10 appetizers and 12 main courses. According to the Fundamental Counting Principle, if there are separate events and the first event can occur in 'm' ways and the second in 'n' ways, then the events together can occur in a total of m x n ways.
Using this principle:
Number of ways to select an appetizer = 10
Number of ways to select a main course = 12
Therefore, the total number of two-course meal combinations = 10 appetizers x 12 main courses = 120 combinations
So, a person can order 120 different two-course meals from this restaurant.

Morgan babysits every Saturday. The equation d = 9.5h
represents how much she earns after h hours. Last week,
she also babysat on Friday and earned $63 for 6 hours.
Which statement is true?
A. Morgan earns the same amount per hour on Friday and Saturday.
B. Morgan’s hourly rate on Friday $12 per hour.
C. Morgan earns more money per hour on Friday.
D. Morgan earns more money per hour on Saturday.
Answer:
Morgan earns more money per hour on Friday.
Step-by-step explanation:
Using the equation d= 9.5h, we see that the hourly rate for Saturday is 9.5, which is $9.50.
On Friday, she babysits 6 hours and earns $63. This is an hourly rate of 63/6 = 10.5, or $10.50.
She earns more money on Friday.
The statement that is true is C. Morgan earns more money per hour on Friday.
From the information given, Morgan babysits every Saturday and the equation is given as d = 9.5hLast week, she also babysat on Friday and earned $63 for 6 hours. This means the rate will be 63/6 = $10.5Therefore, based on this, we can see that the rate on Friday is better.Therefore, Morgan earns more money per hour on Friday.

n the Present Value of an Ordinary Annuity formula, what does the n represent?
a.

c.
number of periods
b.
number of payments
d.
decimal number of percentage
update: got the answer... it is c.
Answer:
C, number of periods
Step-by-step explanation:
ed2022
Final answer:
The 'n' in the annuity formula stands for Option C. the total number of payments or periods, essential for calculating the present value of equally spaced payments over time.
Explanation:
The letter 'n' in the Present Value of an Ordinary Annuity formula represents the total number of payments or periods over which the payments are made. When calculating the present value of an annuity, the formula accounts for each payment being discounted by the interest rate per period. Therefore, the present value of an annuity is calculated by summing up the values of all the payments, each discounted back to their present value.
An example of using the formula could relate to calculating the present value of a series of fixed mortgage payments over time. If the monthly interest rate is 'r', and there are 'n' total payments (for instance, 360 payments for a 30-year mortgage), the present value would account for each payment by discounting it over the number of periods to reflect the time value of money.

Nate ate x ounces of blackberries. Emily ate ⅓ more than that. Write an equation to represent how much Emily ate (y) compared to Nate (x).
Answer: y = x + 1/3
Step-by-step explanation:
Hi, to answer this question we have to write equations with the information given:
The amount of blackberries that each one ate:
Nate (x)= x ounces
Emily ate ⅓ more than that. So, we have to sum the amount eaten by Nate(x) and 1/3.
Mathematically speaking:
Emily (y) = Nate + 1/3
y = x + 1/3

a) work out the probability that both Jim and Sue will pass the driving test.
b) work out the probability that only one of them will pass the driving test.
please help
Answer:
the above images shows the answer to the question
The probability that both Jim and Sue will pass the driving test is 0.42. The probability that only one of them (either Jim or Sue) will pass the driving test is 0.46.
Explanation:This question falls under probability in Mathematics. To solve for these probabilities, we multiply the individual probabilities together.
a) The probability that both Jim and Sue will pass the driving test is found by multiplying the two probabilities together: 0.7 (Jim's probability) * 0.6 (Sue's probability) = 0.42. So, the probability that both will pass is 0.42.
b) The probability that only one of them will pass the driving test is found by adding the probability of the two independent events: Jim passes and Sue fails, or Sue passes and Jim fails. Jim passing and Sue failing would be 0.7 * (1 - 0.6) = 0.28. Sue passing and Jim failing would be 0.6 * (1 - 0.7) = 0.18. Adding these together, the probability that only one of them will pass is 0.28 + 0.18 = 0.46.
