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

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.

Step-by-step explanation:
I am not sure about this
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.

Answer:

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.

How do you factorise with letters and numbers please explain clearly example
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]

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

A solid with dimensions of 3.0 cm X 4.0 cm X 2.0 cm has a mass of 28 g. Will this solid float in
water? (water has a density of 1.00 g/ml)
Answers
Answer:
no because the density is higher than water at 1.166667
Step-by-step explanation:
No, this solid doesn't float in water because the density is higher than water at 1.166667.
To find solid float in water or not.
What is density?Density is the measurement of how tightly a material is packed together.
It is given that :
dimensions of solid is 3.0 cm X 4.0 cm X 2.0 cm
The volume in milliliters is equal to the cubic centimeters.
So volume=3.0 cm X 4.0 cm X 2.0 cm
volume=24 [tex]cm^{3}[/tex]
Mass=28 g
Density= 1.00 g/ml
By the formula,
Density=Mass/ volume
1.00 g/ml=28 g/24 [tex]cm^{3}[/tex]
1.00 g/ml<1.166667
density of solid >density of water
So, the solid sink in water because the density is higher than density of water at 1.166667.
