What is an expression?
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
2x + 4 - 5x is an expression.
3x = 4 is an expression.
We have,
We will find the value of the expression when x = 3.
2x³ = 2 x 3³ = 2 x 3 x 3 x 3 = 64
2x³ + 5 = 2 x 3³ + 4 = 64 + 4 = 68
(2x)³ = 2³ x 3³ = 8 x 27 = 216
(x - 1)³ = (3 - 1)³= 2³ = 8
We see that,
2x³ has the greatest value.
Thus,
The expression that has the greatest value is 2x³

do you divide or multiply for w in the equation A = lw
Answer:
Multiplication
Step-by-step explanation:
This looks like the equation for the area of a rectangle.
Area = Lenght * Width
Given that the "l" variable and the "w" variable or next to each other without '/' or '\' , then we can safely say this a multiplication operation.
If there is no symbol between variables, it is assumed to be short-hand for multiplication instead of writing '*', '.', or 'x' in-between the variables.

Find the measures of all four angles if m∠2 − m∠1=30°
Answer:
m∠1 = m∠3 = 75°
m∠2 = m∠4 = 105°
Step-by-step explanation:
From the figure attached,
m∠1 + m∠2 = 180° [Supplementary angles]------(1)
Since, m∠2 - m∠1 = 30°
m∠2 = 30° + m∠1 -----(2)
By substituting the value of ∠2 from equation (2) to equation (1),
m∠1 + (m∠1 + 30°) = 180°
2(m∠1) + 30° = 180°
2(m∠1) = 150°
m∠1 = 75°
Therefore, m∠2 = 180°- m∠1 = 180° - 75°
m∠2 = 105°
Since, ∠ 2 ≅ ∠4 [Vertical angles]
m∠2 = m∠4 = 105°
Similarly, ∠1 ≅ ∠3 [Vertical angles]
m∠1 = m∠3 = 75°

tan x = -0.25 for 0< x < 720
Answer:
Below in bold.
Step-by-step explanation:
The smallest angle for which -0.25 is the tangent is in the second quadrant and is 165.96 degrees. The other angle in the fourth quadrant is 345.96 degrees.
So for the range 0 to 720, x = 165.96, 345.96 and 360 + 165.96 = 525.96 and 345.96+360 = 705.96 degrees.
At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. write a system of equations that could be used to determine the number of chicken wings in the combination meal and the number of sliders in the combination meal. Define the variables that you use to write the system.
Answer:
x = 2y --------(1)
75x + 250y = 800 ---------(2)
Step-by-step explanation:
Let the number of chicken wings be x
And the number of sliders be y
x = 2y --------(1)
75x + 250y = 800 ---------(2)
The system of equation is x = 2y and 75x + 250y = 800.
Important information:At a particular restaurant, each chicken wing has 75 calories and each slider has 250 calories. A combination meal with chicken wings and sliders is shown to have 800 calories and twice as many chicken wings as there are sliders. here we assume the number of chicken wings be x and number of sliders be yEquation:x = 2y --------(1)
75x + 250y = 800 ---------(2)

Answer:
The y- intercept could only be: B) (0, -3).
Step-by-step explanation:
The Y intercept is found when X=0, so the first value in the ordered pair must be 0. Because the line crosses the y axis BELOW the x axis, the value must be negative. Therefore, out of all the provided options, the answer could only be (0,-3).
Kane is training for a marathone. He started by running 3 miles during every training session. Each week plans to increase the distance of his run by 1/4 mile
Complete question :
Kane is training for a marathon. He starts by running 3 miles during every training session each week plans to increase the distance of his runs by 1/4 mile. Let w be the number of weeks. Write and expression to show the diatance kane runs in a training session after w weeks
Answer:
(11 + w ) / 4
Step-by-step explanation:
Given the following :
Initial miles kane plans to cover per session = 3 miles
Increase in miles covered per session = 1/4 mile per week
Hence, distance covered after w weeks :
Using the sum of an arithmetic progression formula:
Tn = a + (n - 1) d
a = first term = Initial / starting distance = 3 miles
n = nth term = number of weeks = w
d = common difference = constant increase in distance per week = 1/4
Hence, after w weeks :
= 3 + (w - 1) × 1/4
= 3 + (w/4 - 1/4)
= 3 + (w - 1) / 4
Taking L. C. M
(12 + w - 1) / 4
(11 + w ) / 4
The expression that shows the distance Kane runs in a training session after w weeks will be; (11 + w ) / 4
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that the Initial miles kane plans to cover per session = 3 miles
The Increase in miles covered per session = 1/4 mile per week
Using the sum of an arithmetic progression formula to calculate the distance covered after w weeks
Tn = a + (n - 1) d
a = first term = 3 miles
n = nth term = number of weeks = w
d = common difference = the constant increase in distance per week = 1/4
Hence, after w weeks,
= 3 + (w - 1) × 1/4
= 3 + (w/4 - 1/4)
= 3 + (w - 1) / 4
= (12 + w - 1) / 4
= (11 + w ) / 4
