Using scalar multiplication, it is found that 5u = <10,20>.
<h3>What is scalar multiplication?</h3>
- It is when a vector is multiplied by a constant, and it means that each term of the vector is multiplied by the constant.
In this problem, the vector is:
u = <2,4>
Since each term is multiplied by 5:
5u = <5 x 2, 5 x 4> = <10,20>.

35 is the first answer (BAE ~ DAC)
36. We must divide 20 by 2 to get 10 because all the other sides are 2x the size. 3x-5=10 (Add 5) 3x=15 (Divide by 3) x=5 so the last answer choice is correct.
-3x - 18 = 0
-3x = 18
x = -6
The answer is the third one.
