You can write equations for the length (l) and width (w) as
.. l -w = 3
.. 2(l +w) = 14
Divide the second equation by 2 and add the first equation.
.. (2(l +w))/2 +(l -w) = (14)/2 +3
.. 2l = 10
.. l = 5
Then
.. w = l -3 = 2
The length and width are 5 inches and 2 inches, respectively.
You can't simplify 23/67 into a whole number since it is less than one, but you can change it into a decimal by dividing the two numbers.
<span>To catch him in 15 minutes the father must travel 32 miles per hour faster (since 1/4 hr * 32 mph = 8 miles)...
Thus the father must drive at 40 miles per hour. </span>
The graph of vector v with an initial point at (2, 6) and terminal point at
(5, -3). Thus, v = 3i - 9j represents the linear form of v.
<h3>How to find the vector component?</h3>
If we have given a vector v of initial point A and terminal point B
v = ai + bj
then the components form as;
AB = xi + yj
Here, xi and yj are the components of the vector.

Given;
The graph of vector v with an initial point at (2, 6) and terminal point at
(5, -3).
v = (5 - 2)i + (-3 - 6)j
v = (3)i + (-9)j
v = 3i - 9j
Thus, v = 3i - 9j represents the linear form of v.

Answer:
Mixed probabilty
Step-by-step explanation:
What is the probability that the first and second ball chosen are both targets, that is, X1 = 1 X2 = 2?
For this we must study the simple probability of each, for example for the target in that event is 5/13. However for the second chosen but also white in the second event where there is already a total of 12 balls is 4/12.
Thus
In this way is generated for all probabilities
b) In the same way analogous to the past example we can perform all cases of combinations, therefore it would be so
