X can be 3 because:
(3+1)(3)=(4)(3)=12
I believe that is the only possible value for x.
Good luck to you!

Answer:
On Blue print 18 centimeters represents <u>3.6 meters</u>.
Step-by-step explanation:
Given:
Scale is 10 cm = 2 m
We need to find the number of actual meters are represented by 18 1818 centimeters on the blue print.
Solution:
Now we know that;
10 cm = 2 m
so 1 cm = Number of meters in 1 cm.
By using Unitary method we get;
Number of meters in 1 cm =
Now we know that;
1 cm = 0.2 m
18 cm = Number of meters in 18 cm.
Again by using Unitary method we get;
Number of meters in 18 cm =
Hence On Blue print 18 centimeters represents <u>3.6 meters</u>.
Answer:
Step-by-step explanation:
Look at the component form of each vector.
Note that vector c is <4,4> and vector d is <-2,-2>
If one imagined the line that contained each vector, the line for both would have a slope of 1, because
Since they have the same slope they are parallel, but since they are in opposite directions, we often call them "anti-parallel" (simply meaning parallel, but in opposite directions).
If two vectors are parallel, one vector can be multiplied by a scalar to result in the other vector. This means that there is some number "k", such that , or equivalently, and .
If and , we just need to substitute known values and solve for k:
Double checking that k works for the y-coordinates as well:
?
So,
