Step-by-step explanation:
First, find the vector.
= (4,2) - (-3,5)
= (4-(-3),2-5)
= (7,-3)
And then, find the distance.
= √(7² + (-3)²)
= √(49 + 9)
= √58 ✓
The length of the diagonal is the hypotenuse of the fence
The length of the wood is
yards
<h3>How to determine the length of the wood?</h3>
The dimensions of the fence are:
7 ft by 7 ft
The length (L) of the diagonal is calculated using:

This gives

Express as products

Express as radical

Hence, the length of the wood is
yards

Answer:
Putting the value in x = 2 , y =4 in 2x - 2y we get,
2 × 2 - 4× 2= 4-8 = -4
Putting the value in z = 3 in z - 5 we get,
z - 5 = 3 - 5 = -2
Answer:
13-n=4
Subtract both sides by 13
-n=-9
n=9
Step-by-step explanation:
13 less means - and a number means n that you don’t know. is means = sign. And so we get the answer that I gave you. Thank you
