Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?
Answers
She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:
2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276
So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.
To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.
- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.
So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.
Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.
Answer:280 in
Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

Tom Brady was wrong the cost of line cost the same amount Platinum cost $20 a month and $60 for reservations as the muscle fitness there's no better deal or Worse still cost the same amount
Answer: A) 80 - 20 = $60 for registration and 15 + 5 = $20 every month. 20x + 60= cost of Muscle Fitness B) Tom's brother is wrong. They cost the same amount. Platinum Gym cost's $20 a month and $60 for registration as well as Muscle Fitness. There is no better deal or worse deal. They cost the same amount.

Answers
Answer:
In the given equations, "m" represents the slope of the line and "b" represents the y-intercept.
Part A includes four different equations, and they all have different values for "m" and "b". However, since there is no information about any changes in the equations or the values of "m" and "b", it is not clear which equation is being referred to in Part B.
Therefore, without additional context, it is impossible to determine whether "m" or "b" will change in the equation.

What is the Inequality for x for this question : 8(x+4)>-8
Answers
Answer: x>-5
because when you distribute it would be 8x+32>-8. You then subtract 32 (8x>-40). And then you divide both sides by 8 to get x>-5
Answer:
x>-5
Step-by-step explanation:
8(x+4)>-8
Multiply the outside (8), with the inside (x+4)
8*x=8x, 8*4=32
8x+32>-8 ----> What it would look like now
Move the +32 to the other side and turn the signs, + will be -, vice versa
8x>-8-32 ----> = -40
8x>-40
Now, divide both sides by 8, 8x/8=x and -40/8=-5
Final Answer: x=-5
Hope this helps! ;)
