Answers
Answer:
1 .4x2-9= 2x+3,2x-3
2 .16x2-1=4x-1,4x+1
3 .16x2-4=4(2x+1)(2x-1)
4 .4x2-1=(2x+1)(2x-1)
Step-by-step explanation:
16x² − 1 = (4x − 1)(4x + 1) ; 16x² − 4 = 4(2x + 1)(2x − 1); 4x² − 1 = (2x + 1)(2x − 1) ;
4x² − 9 = (2x + 3)(2x − 3)
16x² − 1 is the difference of squares. This is because 16x² is a perfect square, as is 1. To find the factors of the difference of squares, take the square root of each square; one factor will be the sum of these and the other will be the difference.
The square root of 16x² is 4x and the square root of 1 is 1; this gives us (4x-1)(4x+1).
16x² − 4 is also the difference of squares. The difference of 16x² is 4x and the square root of 4 is 2; this gives us (4x-2)(4x+2). However, we can also factor a 2 out of each of these binomials; this gives us
2(2x-1)(2)(2x+1) = 2(2)(2x-1)(2x+1) = 4(2x-1)(2x+1)
4x² − 1 is also the difference of squares. The square root of 4x² is 2x and the square root of 1 is 1; this gives us (2x-1)(2x+1).
4x² − 9 is also the difference of squares. The square root of 4x² is 2x and the square root of 9 is 3; this gives us (2x-3)(2x+3).

A construction crew is paving a road. The crew has already paved 1,000 square feet and can pave at a rate of 300 square feet of road per hour. The function f(x) = 300x
Answers
Answer:
Step-by-step explanation:
i go to southwind what’s the answer ??
The crew would spend 3.33 hours to pave a road that is 1,000 ft².
A linear equation is in the form:
y = mx + b;
where y, x are variable, m is the slope of the line and b is the y intercept.
Let f(x) represent the amount of space paved in x hours.
Given the function:
f(x) = 300x
Therefore to pave 1000 ft²:
1000 = 300x
x = 3.33 hours
The crew would spend 3.33 hours to pave a road that is 1,000 ft².

A)28 inch
B)20 inch
C)16 inch
D)12 inch
Answers
Answer:
A
Step-by-step explanation:
You have to do step by step
Applying the Pythagorean Theorem, the size of the TV that is 16 inches by 12 inches is: B)20 inch
Recall:
Diagonal of a rectangle can be found using the Pythagorean Theorem given as: [tex]d = \sqrt{l^2 + w^2}[/tex]Where, d = diagonal, l and w are the dimensions of the shape.Given:
l = 16 inches
w = 12 inches
Therefore,[tex]d = \sqrt{16^2 + 12^}\\[/tex]

Answers
Complete question :
A balloon is floating above a lake and a sunken canoe is below the surface of the lake the balloons vertical position is 12 meters and the canoes is -4.8 meters the equation the equation 12+d= -4.8 represents the situation 1. What does the Variable d represent 2. What value of d make the equation true
Answer:
d = lake
d = - 16.8
Step-by-step explanation:
The scenario described is represented by the equation :
12 + d = - 4.8
The variable d in the equation would refer to the surface of the lake. Hence, the lake is represented as d ;
For the equation above to be true such that the position of canoe is - 4.8
The we solve for d in the equation given :
12 + d = - 4.8
12 + d - 12 = - 4.8 - 12
d = - 16.8

Find the lowest number divisible by both 6, 5, and 2.
To start, let's list off the numbers divisible by six, and see if we can check any of them off for 5. Since both 2 and 6 are even numbers, we know that if a number is divisible by 6, it's divisible by 2.
6 12 18 24 30 36 42 48 54 60
All of these numbers are divisible by two. Let's find the lowest one that is divisible by 5. We know this by either the umber ending in 5 or 0.
30 is the lowest number that is divisible by 2, 5, or 6.

In 1998 there were 305 students who graduated from high school. In 2019, there were 356 students. What is the rate of change in the number of students?
1. About 1 student per year
2. about 51 students per year
3. about 2 students per year
4. about 5 students per year
Answers
Answer:
3. about 2 students per year
Step-by-step explanation:
The rate of change would be the difference in the number of students divided by the number of years passed.
So, rate of change = [tex]\frac{356-305}{2019-1998}[/tex]
= [tex]\frac{51}{21} = 2.43[/tex]
So it's around 2 students per year.
