Number 6 is C, Number 7 is A. Do you need number 8? if so I will edit answer and add pic
Answer:
8X5=40
Step-by-step explanation:
Let the length equal x
Then the width would be 4x + 8 (8 feet more than 4 times the length)
Area = length x width:
5,472 = x * 4x+ 8
Simplify:
5472 = 4x^2 + 8x
Subtract 5472 from both sides:
4 x^2 + 8x - 5472 = 0
Use the quadratic formula to solve for x.
X = 36
Now you know the length is 36 feet
The width = 4(36) + 8 = 152 feet
Now find the perimeter: 152 + 152 + 36 + 36 = 376 feet.
The answer is B. 376
Answer:
y = -x + 2
Step-by-step explanation:
Lines that are parallel have the same slope but different
y-intercepts.
So the slope of the parallel line is -x
We can input the x and y points given to solve for the new y-intercept
- y = -x + b
- 8 = -(-6) + b
- 8 = 6 + b
- b = 2
The new line is y = -x + 2. Since these two lines are the same, they are coinciding lines.

Answer:
10/12 or 5/6
Step-by-step explanation:
1/2 + 1/2 = 1
5/12 + 5/12 = 10/12 or 5/6
