express the trinomial (3x+8)(x-2)
Answers
Answer:
3x² + 2x -16
Step-by-step explanation:
(3x+8)(x-2)
=> 3x(x) + 3x(-2) + 8(x) + 8(-2)
=> 3x² - 6x + 8x - 16
=> 3x² + 2x -16
The expanded form of the trinomial (3x+8)(x-2) is 3x² + 2x -16
To expand the trinomial (3x+8)(x-2), we can use the distributive property.
First, we multiply the first terms of each binomial: 3x * x = 3x^2.
Next, we multiply the outer terms: 3x * -2 = -6x.
Then, we multiply the inner terms: 8 * x = 8x.
Finally, we multiply the last terms of each binomial: 8 * -2 = -16.
Putting it all together, we have:
(3x+8)(x-2)
=> 3x(x) + 3x(-2) + 8(x) + 8(-2)
=> 3x² - 6x + 8x - 16
=> 3x² + 2x -16

(a+b+c)^2 - a^2+b^2..................
Answers
Answer:
[tex]2b^2 + c^2 + 2ab + 2ac + 2bc[/tex]
Step-by-step explanation:
Whenever you have a parentheses to a power of a number you have to make it the parentheses times itself, so (a+b+c)^2 becomes (a+b+c)(a+b+c), where you then multiply a by a, a by b, a by c, b by a, b by b, b by c, and so on and then add all those numbers up. If you do that you would get a^2 + ab + ac + ab + b^2 + bc + ac + bc + c^2, where you then add them up to get a^2 + b^2 + c^2 + 2ab + 2ac + 2bc. Since you have - a^2 after this, you cancel out the a^2, and finally, you have + b^2 so you add b^2 to it and you get a final answer of 2b^2 + c^2 + 2ab + 2ac + 2bc.

4. Determine both the HCF and LCM of 25 and 200
Answers
Answer:
The LCM of 25 and 200 is 200.
Explanation:
Find the prime factorisation of 25
25 = 5 × 5
Find the prime factorisation of 200
200 = 2 × 2 × 2 × 5 × 5
Multiply each factor the greater number of times it occurs in steps 1 or 2 above to find the LCM:
LCM = 2 × 2 × 2 × 5 × 5
LCM = 200
Answer:
the HCF of 25 and 200 is 25 because it divides both of them and is maximum factor of them.
LCM of 25 and 200 is 200 because it can be divided by both 200 and 25
List the domain and range of the relation.
{(1,-6), (5,5), (0, -6), (5,1) (1,6)}
Answers
Range: {-6, 1, 5, 6}
The domain of a relation is the x-values and the range is the y-values. In a coordinate pair the first digit is x and the second is y. So to find the domain put the first digits of each pair in order from least to greatest. Then to find the range do the same with the second digits in each pair. However, if a value repeats in the domain or range only put it once.

7ab+14b how do I put that in brackets and what are the rules when factoring
Answers
Answer:
7b(a+2)
Step-by-step explanation:
First. look at the coefficient. See if they are common multiple of some number. If so find the GCF between them.
Then find the variable both terms share.
Put the GCF coeffiecnt and the variable both terms share outside the parentheses.
Inside the parenthesis will be a term that multiplied by the term outside of the parenthesis will equal the original equation.
For example, 7ab+14b.
Set up equation.
[tex]7ab + 14b[/tex]
Both terms share a b variable and 7 and 14 GCF is 7 so
let factor out 7b.
[tex]7b(a + 2)[/tex]
Why is inside the parenthesis is the term (a+2). If we divide 7ab+14b by 7b separately we get
[tex]a + 2[/tex]

classify ∠2 and ∠6. Compare angle measures, and give the postulate or theorem that justifies it.
Answers
Answer:
Explanation
Step-by-step explanation:
Angles 2 and 6 are corresponding angles in a transversal meaning they have the same measure.
The two straight lines are parallel and the co-position angles are equal, ∠2 =∠6
What is angle?
An angle is formed when two straight lines as well as rays meet at a single endpoint. The point where two points converge is known as an angle's vertex. The term "angle" comes from the Latin word "angulus," that also means "corner."
Parts of Angles:Vertex: A vertex is a corner of an angle or the intersection of two lines or sides.
Arms: The angle's two sides joined at a single end.
Initial Side: A straight line from which an angle is drawn is referred to as the reference line as well.
The side that the angle measurement is done up to is known as the terminal side.
Acute angles have a vertex angle that is less than 90 degrees.
Obtuse angles range from 90° to 180°.
At its vertex, a right angle has an exact measurement of 90°.
A straight angle is one that is 180° in length.
Reflex angles range from 180° to 360°.
A 360° angle is a full circle.
Solution:
The third straight line intersects the two parallel lines, creating angles 2 and 6.
∴ ∠2 and ∠6 are on the same side of the section line, and on the same side of the truncated parallel line.
∴ ∠2 and ∠6 are co-positions angles.
∴ ∠2 =∠6
Theorem :
The two straight lines are parallel and the co-position angles are equal.

Answer: m=6
Step-by-step explanation:
Take the inequality 50m + 11 < 75m + 25 and replace the m with (6).
This makes 50(6) + 100 < 75(6) +25. Multiply on each side.
The result is 300 + 100 < 450 + 25 which is the same as 400 < 475.

Write as an algebraic expression
Answers
The answer you are looking for is 1/5(a+34).
Solution/Explanation:
"Of"="multiplication (x)."
So, therefore, write it like this, to get the better picture and visualization,
1/5 times the sum of a number "a" and "34."
"Sum" obviously is related to "addition."
So, therefore, we can simplify the algebraic expression a little bit more,
1/5 times (a+34).
Now, we can finally write it like this.
1/5x(a+34).
The more proper way to write it, however is like this:
1/5(a+34).
So, therefore, the final answer is 1/5(a+34).
I hope that this has helped you. Enjoy your day, and take care!
The given statement is required in the form of an algebraic expression.
The statement is a fifth of the sum of number a and 34.
The sum means addition
So, the sum is [tex]a+34[/tex]
The statement states a fifth of which, means multiplied by [tex]\dfrac{1}{5}[/tex]
The algebraic expression will be the product of [tex]\dfrac{1}{5}[/tex] and [tex](a+34)[/tex]
