The length of a rectangle is shown below: On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair 1, 2, and the point B is on ordered pair negative 3, 2. A straight line joins the points A and B. If the area of the rectangle to be drawn is 12 square units, where should points C and D be located, if they lie vertically below the line that connects B and A, to make this rectangle? C(−3, −2), D(1, −2) C(−3, −1), D(1, −1) C(−3, −4), D(1, −4) C(−3, −5), D(1, −5)

Mr. Heath is TRYING to grow his hair out! Currently, his hair is 0.25 inches long. Each month, it grows 0.5 inches. His goal is to have hair that is 2.5 inches long. Let x be the number of months that Mr. Heath grows hair. Which of the equations represents Mr. Heath's hair growth journey? *
Answer: 0.25 + 0.5x = 2.5
Step-by-step explanation:
0.25 = the how long his hair is right now
0.5 = how much it grows each month
X= how many months it takes to reach 2.5 inches of hair
2.5= how long he'd like his hair to be

Given the equation 2x + 4 = 4x - 2, select the reasoning that correctly solves for x.
1) Add 2, subtract 2x, then divide by 2.
2) Add 2, subtract 4x, then divide by -2.
3) Subtract 4, subtract 2x, then divide by-2.
04) Subtract 4, subtract 4x, then divide by 2.
Answer:
04) Subtract 4, subtract 4x, then divide by 2.
Answer:
option A.
Step-by-step explanation:
2x + 2 + 4 = 4x - 2 + 2
2x - 2x + 6 = 4x - 2x
3 = x OR x = 3
PLEASE HELP if 5 more than 3 times a number is -4, what is the number?
Answer:
x = -3
hope it's helpful ❤❤❤
THANK YOU.
Hey there!
The answer to your question is "n = -3"
First, we can start by writing the equation as it says. "3 times a number" represents a number times 3, or "3n"
3n
Next, "5 more" represents addition, so "+ 5"
3n + 5
Finally, "is -4" means it is equal to -4, so "= -4"
3n + 5 = -4
Now that we have our equation, we can solve:
3n + 5 = -4
First, we subtract "5" from both sides of the equal sign:
3n = -9
Lastly, we divide both sides by "3".
n = -3

the figure below is made of two triangular prisms. what is the volume of the figure
Answer:
896 cubic inches
Step-by-step explanation:
V (Δ prism) = 1/2 · height · base · length
V (top prism) = 1/2(6)(12)(14)
V (top prism) = 504 in³
V (bottom prism) = 1/2(7)(8)(14)
V (bottom prism) = 392 in³
504 + 392 = 896

Step-by-step explanation:
Mark wants to make an enclosure for his cows.
He has 44 metres of fencing.
He wants the width to be 8 metres less than the length.
What dimensions should the field have?
?
Answer:
the length and width be 15 meters and 7 meters respectively
Step-by-step explanation:
The computation of the dimension of the field is given below;
Let us assume the fencing be p
Length be x
And, the width be x - 8
So,
P = 44
P = x - 8 + x - 8 + x + x
= 4x - 16
Now
4x - 16 = 44
4x = 44 + 16
4x = 60
x = 15
And, the width be 15 - 8 = 7
So, the length and width be 15 meters and 7 meters respectively
Andre drives a bike for 4 hours covering 160 km. Find the distance covered by him in 7 hours.
Answer:
I think is 280km :))))))
Answer:
Andre covered 280km.
Step-by-step explanation:
I would say make a proportion:
?= distance covered
4 - 160
7 - ?
Solve: 7×160÷4=280.
Sample Response: To find the image after a reflection over the x-axis, I would negate the y-coordinate. To find the image after a reflection over the y-axis, I would negate the x-coordinate. So, reflecting the point (5, 2) over the x- and y-axis, I would get (–5, –2).
Which did you include in your response? Check all that apply.
Negate the y-coordinate.
Negate the x-coordinate.
Get the point (–5, –2).

There are 2 rectangular windows in Ms.
Ridley's dining room. One window is 31 inches
wide and 32 inches tall. The other window is
27 inches wide and 32 inches tall. What is the
difference in the areas of the windows in Ms.
Ridley's dining room?
8 square inches
4 square inches
132 square inches
128 square inches
Answer:
128 square inches
Step-by-step explanation:
Window one's area is 31 times 32 which is 992 in^2
Window two's area is 27 times 32 which is 864 in^2
Subtract 992 from 864 to get the difference

Which equation represents a line which is parallel to the line 7x - y = 4?
Answer:
Step-by-step explanation: step : Place the given line’s equation in slope- intercept form y = mx + b. A line parallel to this line will have the same slope.
7x - y = 4. Yields y = 7 x - 4. Therefore y = 7x - 5 is the correct answer.

$72 game with a 20% discount and 7.5% tax
Answer:
Cost of game after discount = 72 - 20% of 72 = $57.6
Cost after tax = 57.6 + 7.5% of 57.6 = $61.92
So, the required cost is $61.92.
