The coefficient of x⁴y³ term in the expansion of (x - 2y)⁷ is 280.
What is expression?Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement.
Given expression:
(x - 2y)⁷
Expand this as given below,
(x - 2y)³ × [(x - 2y)²]²
(x³ + 6x²y + 12xy² + 8y³) × [(x² + 4y² - 4xy)]²
Solve the above expression to get,
x⁷ + 14x⁶ + 84x⁵y² + 280x⁴y³ + 560x³y⁴ + 672x²y⁵ + 448xy⁶ + 128y⁷
Here, the coefficient of the x⁴y³ is 280,
Therefore, the coefficient of x⁴y³ term in the expansion of (x - 2y)⁷ is 280.

For what value(s) of w does the equation 7 + 3x - 1 = w(x + 2) have infinitely many solutions?
Answer:
w=3
Step-by-step explanation:
7 + 3x - 1 = w(x + 2)
Solve for w
Distribute
7 + 3x - 1 = wx + 2w
Combine like terms
3x+6 = wx+2w
For this to have infinite terms
3x = wx and 6 = 2w
3x = wx
Divide by x
3 =w
and 6 = 2w
Divide by 2
6/2 = 2w/2
3 =w
When w = 3, there will be infinitely many solutions

Yesterday only 13 students were absent. The is 4% of the schools enrollment. What is the schools total enrollment?
Answer: 325 students
Step-by-step explanation:
13 students were absent and this is 4% of the school's total enrollment.
If 13 students represent 4% of the students, assume that x represents 100% of the students:
4% * x = 13
0.04x = 13
x = 13/0.04
x = 325 students
There are 325 students in this school.

After 10 weeks of work, bob has $1200. After 15 weeks of work Bob has $1800. After 20 weeks of work Bob has $2400. Write the firs four terms of a sequence that represents this situation. Writ and equation to model the situation
Answer:
1200,1800,2400,3000
5x = 600x
Step-by-step explanation:
The first four terms would be
1200,1800,2400,3000
As we can see that
After 10 weeks of work bob has $1200
After 15 weeks of work, bob has $1,800
So the more the weeks would be, the more the earnings it is
And, the difference of the earnings is
= $1,800 -$1,200
= $600
The equation would be
5x = 600x
So if we assume x = 1
So
5 = 600
if we assume x = 2
So
10 = 1200
and so on
Martina and Ashanti worked together on an art project. They began working at 3:25 p.M. And finished working at 5:15 p.M. How long did the girls work together on their art project?
Answer:
The girls worked together on their art project for 1 hour and 50 minutes.
Step-by-step explanation:
In order to find the answer you have to find the difference between the time they began working and the tine they finished working. You have to subtract 3:25 from 5:15.
Since 25 minutes on the time they began working is higher than 15 minutes, you have to subtract 1 from the time they finished working that is 5 hours:
5-1=4
Then, you have to increase the minutes on the time they finished working by 60:
15+60=75
Now, you have to subtract the minutes which would be 25 from 75:
75-25=50
Finally, you have to subtract the hours which would be 4 minus 3:
4-3=1
The result would be 1 hour and 50 minutes.
According to this, the answer is that the girls worked together on their art project for 1 hour and 50 minutes.

Mr. D'Agostino decided he wanted to build a pool in his backyard this summer. He sketched a drawing that had a scale of 1 in. = 4 feet. If the drawing had a length of 4 feet and a width of 5 feet, what is the actual area of the pool?
Answer:
46080 ft²
Step-by-step explanation:
Given :
Scale :
1 in = 4 feets
Recall :
I foot =. 12 inches
Length of drawing = 4 feets
Length of drawing in inches = 4 * 12 = 48 inches
Width of drawing = 5 feets
Width of drawing in inches = 5 * 12 = 60 inches
Actual length of pool = 48 * 4 = 192 feets
Actual width of pool = 60 * 4 = 240 feets
The actual area of the pool :
Length * width
192 feets * 240 feets = 46080 ft²

A. L = 0.2w + 5
B. L = 0.2w - 5
C. w = 0.2L + 5
D. w = 0.2L - 5
Answer:
L = 0.2w + 5
Since there is already 5 miles, your adding 0.2w. Its not 0.2L because that is the total length and its the sum.
