A=(1,2) and b=(2, - 1) . Find 4a - 3b
1st carry out the scalar multiplication 4a and -3b
4a =[4(1) , 4(2) ] = (4 , 8)
-3b = [-3(2) . -3(-1)] = (-6 , +3)
4a - 3b = [(4-6) , (8+3)] = (-2 , 11)
A) to get the longest object do a^2 + b^2 =c^2
25^2+25^2=c^2
Then
c^2 +50^2
Square root the answer to get the longest object
B) 10^2+12^2=c^2
Then
c^2+58^2
Square root the answer to get the longest object
C)whichever has the largest answer
Answer:
k=3 z=-6
Step-by-step explanation:
12k=36
k=36/12
k=3
-6z=36
z=36/-6
z=-6
12(3)-6(-6)=36
