Answer:
the answers Is c. x=4
Step-by-step explanation:
do substitution 2*4+6=14
and 6*4-10=14
Answer:

Step-by-step explanation:
Simply use the fact that the change in x squared + the change in y squared = the distance squared. (The Pythagorean Theorem)
1^2 + 4^2 = d^2
1 + 16 = d^2
17 = d^2
d = √17

Answer:
10
Step-by-step explanation:
Given: 20 yards of ribbon in total. Need to make 2 yards each.
To find out how many yards you need to cut, divide:

So, you need to make 10 cuts for the 20 yards.
Hope this helped.
E^x^2 - 9 = 1
e^x^2 = 1 + 9 = 10
Ln e^x^2 = Ln 10
x^2 = Ln 10
x = sqrt (Ln 10) = 1.517
x = 1.517
Given that x is the number of chains;
7(4+3) = 7 * 7 = 49 feet
