Express the perimeter of the triangle as a polynomial
8x - 2
5x - 4
9x - 3
Answer:
P = a + b + c
P = (8x + 2) + (5x - 4) + (9x + 3)
P = 8x + 5x + 9x + 2 - 4 + 3
P = 22x + 1
I hope this helps.
Find the perimeter. Simplify your answer.
Answer:
perimeter=32t units
Step-by-step explanation:
let:
a=8t-2
b=8t+2
perimeter=2(a+b)
Subtitute values of a and b:
=2(8t-2+8t+2)
=2(16t)
=32t units
Light bulbs cost £3.30 each.Yasmin buys as many as she can with £40.How much change should she get?Give your answer in pounds, £
Answer:
40p / £0.04
Step-by-step explanation:
£3.30 X 10 = £33
£3.30 X 2 = £6.60
£6.60 + £33 = £39.60
£40 - £39.60 = 40p / £0.04
is
-f(x)
the same as
f(-x)
Answer:
In general, no.
Step-by-step explanation:
f(-x) = -f(x) when the function is "odd." Such a function is symmetrical about the origin. This will not generally be the case, so, in general, -f(x) ≠ f(-x).
_____
Additional comment
When f(-x) = f(x), the function is "even." It is symmetrical about the y-axis.
Among trig functions, sin(x) is odd, and cos(x) is even.
Among polynomials, any polynomial with only odd-degree terms is odd; any polynomial with only even-degree terms is even.

Answer:
Your anwser would be

Answer:
$33,280
Step-by-step explanation:
Since your salary is $32,000, you would take 4% from $32,000 and add it to the current salary. 4% can be shown as .04 in decimal form. If you multiply 32,000 by .04 you get 1280. Add 1,280 to 32,000 and you get 33,280.

Give your answer in its simplest form.
PLEASE HELP BRAINLIST TO FASTEST AND CORRECT ANSWER
Answer:
Well lucy has a 50/50 chance to get a odd card so that is it
Step-by-step explanation:
The ratio of even cards to odd cards that Lucy has is 3:4 in its simplest form.
Let's denote the number of even cards as "x" and the number of odd cards as "y".
The probability of choosing an even card is given as [tex]\frac{3}{7}.[/tex]
The probability of choosing an even card is calculated by dividing the number of even cards by the total number of cards:
Probability of choosing an even card = Number of even cards / Total number of cards
Therefore, we have:
[tex]\frac{3}{7} = \frac{x}{x+y}[/tex]
To find the ratio of even cards to odd cards, we can set up the equation:
[tex]\frac{x}{y} = \frac{3}{4}[/tex]
Therefore, the ratio of even cards to odd cards that Lucy has is 3:4 in its simplest form.

11,466,_39 is divisible by 3
Answer:
0,3,6,9
Step-by-step explanation:
The divisibility rule for 3 is to add up all the digits and see if it's divisible by three. 1+1+4+6+6+3+9= is divisible by three. So the digit also has to be divisible by 3
Answer:
There are 4 possible answers and they are: 0, 3, 6 or 9
=======================================================
Explanation:
Recall the divisibility by 3 rule is that if the digits add to a multiple of 3, then the original number itself is also a multiple of 3.
Let x be the unknown digit. The number 11,466,x39 has its digits add to:
1+1+4+6+6+x+3+9 = x+30
Notice that 30 is a multiple of 3 since 30 = 3*10. This must mean x has to be a multiple of 3 as well. If x is a single digit and a multiple of 3, then we have the following options: {0,3,6,9}
If any of 0, 3, 6, or 9 replaces x, then the number 11,466,x39 is a multiple of 3.
In other words,
11,466,039 is a multiple of 311,466,339 is a multiple of 311,466,639 is a multiple of 311,466,939 is a multiple of 3because all the digits add to some multiple of 3.
A high school teacher teaches three classes per day. Her first class has double the number of students as her
second class, while her third class has 5 more students than her second class. In total, she teaches 65 students.
The equation 2x + x + (x + 5) = 65 represents this scenario, where x is the number of students in her
second class.
How many students are in her second class?
Answer: 15 students in her second class.
Step-by-step explanation:
Let A, B, and C stand for the number of students in each class. See the attached table.
The column labelled "Students" is formed by assinging B to the second class and finding how the other two classes relate to B. Class A has twice as many students as class B, so A = 2B. Class C has 5 more students than B, so C = B+5.
The total students amount to 65, whcih is the sum of A, B, and C:
A + B + C = 65
Substitute the values of A and C into this equation:
A + B + C = 65
2B + B + (B+5) = 65
4B + 5 = 65
4B = 60
B = 16
Use B=16 and solve for the other two classes (dotted blue line).

Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 30. How old is each sister?
(a) Write an equation that represents the situation. Explain any variable used.
(b) Solve the equation from Part (a). Show your work. State your solution as a complete sentence.
Answer:
Kim's age is twice of that of her sister. We'll let k2 = Kim and k = Kim's sister.
So, k2. When you add Kim's age to her sister age you get 36.
Because Kim is twice the age of her sister k2. And because it said 'add' then we put a + sign. k2 + s = 36. Now let's solve it.
k2 + k = 36 < Given
3k = 36 < Combine like terms
k = 12 < Divide both sides by 3
We know Kim's sister is 12 y/o but what about Kim herself? Earlier we assigned Kim to k2. Substitute 12 for k and you get 12(2) = 24
Kim's sister is 12 y/o and Kim is 24 y/o
Step-by-step explanation:
Mark as brainliest please
Kim's age = x
Age of her sister = y
Acoording to conditions, [tex]x=2y[/tex]
The equation is,
[tex]x+y = 30 \\\\\implies 2y + y = 30\\\\\implies 3y = 30 \\\\\implies y = 10\\\\x = 2y = 2(10) = 20\\\\\text{Hence, Kim is 20 years old and her sister is 10 years old.}[/tex]

Answer:

Step-by-step explanation:
The triangles are congruent. Also, a triangle has a sum of 180 degrees for its interior angles.
Angles D and A are both unknown.
Angles O and P are both 55.
Angles G and W are both 37.
37+55 = 92
That means there would be 88 degrees left for the unknown angle to get to the total of 180 degrees.
92 + 88 = 180
