Answer:
If a shape is a square, then it is a quadrilateral
Step-by-step explanation:
Quadrilateral means four sided shape, so automatically, because a square has 4 sides, you know it is a quadrilateral. But not all quadrilaterals are a square, you could have a rectangle which is four sides so you know that this statement is wrong "If a shape is a quadrilateral, then it is a square." Therefore, the answer is "If a shape is a square, then it is a quadrilateral
Answer:
![(4x+1)(-2x^2-3)](https://tex.z-dn.net/?f=%284x%2B1%29%28-2x%5E2-3%29)
Step-by-step explanation:
The given expression is ![-8x^3-2x^2-12x-3](https://tex.z-dn.net/?f=-8x%5E3-2x%5E2-12x-3)
First of all we make groups
![(-8x^3-2x^2)+(-12x-3)](https://tex.z-dn.net/?f=%28-8x%5E3-2x%5E2%29%2B%28-12x-3%29)
Take GCF from each group
![-2x^2(4x+1)-3(4x+1)](https://tex.z-dn.net/?f=-2x%5E2%284x%2B1%29-3%284x%2B1%29)
Now, we can factored out the common term
![(4x+1)(-2x^2-3)](https://tex.z-dn.net/?f=%284x%2B1%29%28-2x%5E2-3%29)
Hence, the resulting expression is
![(4x+1)(-2x^2-3)](https://tex.z-dn.net/?f=%284x%2B1%29%28-2x%5E2-3%29)

Answer:
y = -7; x = 4
Step-by-step explanation:
x - 7y = 53
x = 7y + 53
-4x - 5y = 19
-4(7y + 53) - 5y = 19
-28y - 212 - 5y = 19
-33y = 231
-11y = 77
y = -7
x - 7(-7) = 53
x + 49 = 53
x = 4
Answer:
A. 220 feet
B. 220 feet
C. 5 rolls of ribbon
Step-by-step explanation:
Given.
Number of box ![= 80](https://tex.z-dn.net/?f=%3D%2080)
We need
feet of ribbon for each box wrapping.
Each roll of ribbons is 50 feet.
A.
Estimated value of ribbon for 80 boxes.
= Number of box
ribbon for each box
![= 80\times 2\frac{3}{4}\\](https://tex.z-dn.net/?f=%3D%2080%5Ctimes%202%5Cfrac%7B3%7D%7B4%7D%5C%5C)
![= 80\times \frac{11}{4}](https://tex.z-dn.net/?f=%3D%2080%5Ctimes%20%5Cfrac%7B11%7D%7B4%7D)
![= 20\times 11](https://tex.z-dn.net/?f=%3D%2020%5Ctimes%2011)
![= 220 feet](https://tex.z-dn.net/?f=%3D%20220%20feet)
The estimated number of feet of ribbon for 80 boxes is 220 feet.
B. Exact the number of feet of ribbon for 80 boxes is 220 feet.
C.
Number of rolls for wrapping 80 large boxes.
Each roll of ribbon is 50 feet and we are required 220 feet of ribbons.
rolls of ribbon = total required ribbon divided by how much feet in rolls.
rolls of ribbons = ![\frac{220}{50}](https://tex.z-dn.net/?f=%5Cfrac%7B220%7D%7B50%7D)
rolls of ribbons = ![4.4](https://tex.z-dn.net/?f=4.4)
Therefore, the total required rolls for 220 feet of ribbons is 5
