2(12x + 6)
–6(–4x – 2)
–3(8x – 4)
12(1 + 2x)
–4(–6 – 3x)
Answers
Answer:
2(12x + 6)
-6(-4x - 2)
12(1 + 2x)
The expressions that are equivalent to 24x + 12 are:
2(12x + 6)
-6(-4x - 2)
12(1 + 2x)
Let's go through each expression and simplify them to determine if they are equivalent to 24x + 12.
2(12x + 6):
We can use the distributive property to simplify this expression:
2 * 12x + 2 * 6 = 24x + 12
This expression is equivalent to 24x + 12.
–6(–4x – 2):
Again, using the distributive property, we simplify:
–6 * –4x + –6 * –2 = 24x + 12
This expression is equivalent to 24x + 12.
–3(8x – 4):
Once again, applying the distributive property:
–3 * 8x + –3 * –4 = –24x + 12
This expression is not equivalent to 24x + 12.
12(1 + 2x):
Using the distributive property:
12 * 1 + 12 * 2x = 12 + 24x = 24x + 12
This expression is equivalent to 24x + 12.
–4(–6 – 3x):
Applying the distributive property:
–4 * –6 + –4 * –3x = 24 + 12x = 12x + 24
This expression is not equivalent to 24x + 12.

3x + 2, x?, and 2x when x = 4
Answers
Answer:
[tex]3x+2 \ne x^2 \ne 2x[/tex] for [tex]x = 4[/tex]
Step-by-step explanation:
Given
Shape: Triangle
Dimension: 3x + 2, x^2 and 2x
[tex]x = 4[/tex]
Required
Determine if it has equal sides
To do this, we simply substitute 4 for x in the given dimensions
3x + 2
[tex]3x + 2 = 3 * 4 + 2[/tex]
[tex]3x + 2 = 12 + 2[/tex]
[tex]3x + 2 = 14[/tex]
x^2
[tex]x^2 = 4^2[/tex]
[tex]x^2 = 16[/tex]

(d) Describe what the number 30 in Part (c) mean in the context of the situation?
Answers
Answer:
(c) Paul's model predicts a score of 51 for 3 hours
(d) 30 represents the y intercept
Step-by-step explanation:
Given
[tex]y = 7x + 30[/tex]
Solving (c): What is y when x is 3
Substitute 3 for x in [tex]y = 7x + 30[/tex]
[tex]y = 7*3 + 30[/tex]
[tex]y = 21 + 30[/tex]
[tex]y = 51[/tex]
Solving (d): What does 30 represent
An equation is represented as:
[tex]y = mx + b[/tex]
Where
[tex]b = y\ intercept[/tex]
Compare: [tex]y = mx + b[/tex] to [tex]y = 7x + 30[/tex]
[tex]b = 30[/tex]
This implies that 30 represents the y intercept

The equation C(l) = l3 – l2 + l + 2.5 models the cost to mail a package as a function of its length. To the nearest quarter inch, approximately what is the length of a package that costs $11.00 to mail? Enter your answer as a decimal.
Answers
Answer:
2.25
Step-by-step explanation:
Given the cost model:
C(l) = l3 – l2 + l + 2.5
l = Length fo package
The length of a package that cost $11.00
11 = l³ - l² + l + 2.5
From the table given :
Length of mail which cost $11 will just be slightly greater Than 2 as the cost of 2 length mail cost 8.50
Taking l as 2.20
2.2^3 - 2.2^2 + 2.2 + 2.50 = 10.508
Taking a slightly higher value :
Put l = 2.25
2.25^3 - 2.25^2 + 2.25 + 2.50 = 11.078
Ww can conclude that the length of mail would be 2.25

XVW and WVT
Step-by-step explanation:
Two angles are supplementary angles when the sum of their measures is equaled to 180 degrees.
180 degrees = a line.
YVZ and WVU are Vertical Angles
YVZ and ZVT are not straight lines together.
XVW and WVU are on the same straight line but you have to add UVT in order to get 180.
XVW and WVT are the only ones that look like they can add up to 180 degrees.
XVW and WVT should be the answer, I really hope this helps!
In a right angled triangke abc the perpendicular and the base measure 3 cm find hypotenus and three trignometrice ratios
Answers
Given:
In a right angled triangle ABC the perpendicular and the base measure 3 cm.
To find:
The hypotenuse and three trigonometric ratios.
Solution:
Pythagoras theorem:
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Use Pythagoras theorem in triangle ABC.
[tex]Hypotenuse^2=(3)^2+(3)^2[/tex]
[tex]Hypotenuse^2=9+9[/tex]
[tex]Hypotenuse=\sqrt{18}[/tex]
[tex]Hypotenuse=3\sqrt{2}[/tex]
The three trigonometric ratios are
[tex]\sin \theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]
[tex]\sin \theta=\dfrac{3}{3\sqrt{2}}[/tex]
[tex]\sin \theta=\dfrac{1}{\sqrt{2}}[/tex]
Similarly,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos \theta=\dfrac{3}{3\sqrt{2}}[/tex]
[tex]\cos \theta=\dfrac{1}{\sqrt{2}}[/tex]
And,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
[tex]\tan \theta=\dfrac{3}{3}[/tex]
[tex]\tan \theta=1[/tex]
Therefore, the hypotenuse is [tex]3\sqrt{2}[/tex] cm and three trigonometric ratios are [tex]\sin \theta=\dfrac{1}{\sqrt{2}}, \cos \theta=\dfrac{1}{\sqrt{2}}, \tan \theta=1[/tex].

[tex]y - x = 5[/tex]
[tex]x = y - 5[/tex]
Step-by-step explanation:
No options were given but the question can still be solved
Given
From the first statement, we have:
[tex]Maria = x[/tex]
From the second, we have:
[tex]Anika = 5\ more[/tex]
Required
Determine the relationship between the amount of rice they bought
5 more means 5 + Maria.
So, [tex]Anika = 5\ more[/tex] becomes
[tex]Anika = 5 + Maria[/tex]
Substitute x for Maria
[tex]Anika = 5 + x[/tex]
For proper expression, let Anika be y
[tex]y = 5 + x[/tex]
Subtract x from both sides
[tex]y - x = 5[/tex]
Make x the subject
[tex]x = y - 5[/tex]

Activity 1 of 2
What explicit expression can be used to find the nth term of this sequence?
Answers
Answer:
2n^2 + n + 4.
Step-by-step explanation:
7, 14, 25, 40, 59
The differences are 7, 11, 15, 19 which is arithmetic sequence so the given sequence is quadratic.
Compile a table:
n 1 2 3 4 5
term 7 14 25 40 59
Diff: 7 11 15 19
Diff: 4 4 4 - this indicates that first part is 2n^2.
2n^2 2 8 18 32 50
term-2n^2 5 6 7 8 9
- the nth term for the last sequence is 5+ (n - 1)d =
= 5 + (n - 1)* 1
= n + 4.
So nth term for the original sequence is 2n^2 + n + 4.
