Answer:
the first piece of rope would be 4 feet
Step-by-step explanation:
4 + 8 + 9 = 21
I’m guessing C, but I’m not for sure
Answer:
The length between the two points is RT = 1.3 units
Step-by-step explanation:
The coordinates of the point R and T are R(2,1.2) and T(2,2.5).
Now, by DISTANCE FORMULA:
The distance between two coordinates P and Q with coordinate P(a,b) and Q(c,d) is given as:
So, here the distance RT = 
or, RT = 1.3 units
Hence, the length between the two points is RT = 1.3 units
4(5x + 7) = 128
First, I'd do distributive property and get:
20x + 28 = 128
Then, subtract 28 from each side.
20x = 100
Next, I'd divide 100 by 20 = 5
x = 5
4 *(5(5) + 7) = 128
5 * 5 = 25
4 * (25 + 7)
4 * 32 = 128
Therefore, the perimeter = 2l + 2w
l = 4
w = 5x + 7
BUT we know that x = 5
w = 5(5) + 7 = 32
2(4) + 2(32)
8 + 64 = 72
Therefore, the perimeter would be 72 inches.
It depend on where you are working at that isn't a specific question
