A square has a side length of (x+4). What is the expression that represents the area of the square?
x2+16x squared plus 16
x2+8x+16x squared plus 8 x plus 16
x2+16x+16x squared plus 16 x plus 16
x2+8x+8
The expression x² + 8x + 16 represents the area of the square.
What is the area of the square?The area of the square is defined as the product of the length and width.
Given data as:
A square has a side length of (x+4)
The area of the square = (x+4)(x+4)
The area of the square = (x+4)²
The area of the square = x² + 2(x)(4) + 4²
The area of the square = x² + 8x + 16
Hence, the expression x² + 8x + 16 represents the area of the square.

Which equations would the following absolute value equation produce? (Note: You are NOT solving the equation) |5z| = 40
Answer:
5z = 40 and 5z = -40
Step-by-step explanation:
Since the equation is absolute value it will produce two equations 5z=40 and 5z=-40 since the 5z could be positive or negative, we can't tell with the absolute value bars

} A rectangle has an area of 25 square feet. A similar rectangle has an area of 200 square feet. What is ratio of the areas of these similar rectangles(smaller to larger, order always matter! )?
Answer:
The ratio of smaller rectangle to larger is 1 : 8.
Step-by-step explanation:
Given that:
Area of smaller rectangle = 25 square feet
Area of larger rectangle = 200 square feet
Ratio of areas of these similar rectangles;
Smaller rectangle : Larger rectangle
25 : 200
1 : 8
Hence,
The ratio of smaller rectangle to larger is 1 : 8.

which ordered pair is a solution to the system of inequalities?
Answer:
Option A
Step-by-step explanation:
System of the inequalities is,
y ≥ 2x
y < x + 4
By satisfying these inequalities with the points given in the options we can get the answer.
Option (A). (2, 5)
y ≥ 2x
5 ≥ 2(2)
5 ≥ 4
True.
y < x + 4
5 < 2 + 4
5 < 6
True
Therefore, Option (1) is the answer.
Option (B) (1, 6)
y ≥ 2x
6 ≥ 2(1)
6 ≥ 2
True.
y < x + 4
6 < 1 + 4
6 < 5
False.
Therefore, it's not the solution.
Option (C) (2, 3)
y ≥ 2x
3 ≥ 2(2)
3 ≥ 4
False.
y < x + 4
4 < 2 + 4
4 < 6
True.
Therefore, It's not the solution.
Option (D) (1, 5)
y ≥ 2x
5 ≥ 2(1)
5 ≥ 4
True.
y < x + 4
5 < 1 + 4

A is directly proportional to B and when A = 4 , B = 8 8. Find A when B = 44 . please can I have the working out
Answer:
A = 2
Step-by-step explanation:
If A = 4 when B = 88, we can divide both A and B by 2 to find their values.
88/2 = 44
4/2= 2
We can also check this by dividing 88 by 4 to figure out that A = 1 when B = 22
We can then multiply both the values of A and B to get a proportional relationship of A = 2, B = 44

therefore,
2x+12 = 3x - 22
2x = 3x -22 - 12
2x = 3x - 34
34 = 3x - 2x
34 = x
therefore x = 34

Johnny's inspecting the finished toys in toy factory he found that 4 the toys were damaged and 16 were not based on this data how many of the next 20 toys would you expect to be damaged. Please explain I do not understand
Answer:
4 is expected to be damaged out of the next 20
Step-by-step explanation:
From the observation made, we have that 4 of the toys were damaged and 16 were not damaged
Thus, the probability of having a damaged toy is 4/20 = 1/5
Now, for the next 20; we have 1/5 of them expected to be damaged
So, the expected damaged number out of the next 20 will be:
1/5 * 20 = 4

Bob completed a race in half of an hour. He ran 4 laps. Each lap was ran equally. How much of an hour did bob run on each lap?
Answer:
Time taken for each lap = 3/8 of an hour
Step-by-step explanation:
Given:
Time taken for 4 laps = [tex]1\frac{1}{2}[/tex] = 3/2 hours
Find:
Time taken for each lap
Computation:
Time taken for each lap = Time taken / Number of laps
Time taken for each lap = (3/2) / 4
Time taken for each lap = 3/8 of an hour
